From the beginning of the series, it is evident that Duncan and Courtney are polar opposites, which causes a great deal of conflict between them during the first few episodes of Total Drama Island. In spite of this, they are often paired up together in challenges, which sometimes leads to insinuations that Courtney has feelings for him, which she steadfastly denies. Duncan, on the other hand, never denies that he is attracted to Courtney, and often openly accuses Courtney of wanting him. Despite the fact that she criticizes him at every opportunity, Courtney eventually shows signs of having a secret crush on Duncan, and there are indications of a mutual attraction growing between the two. This romantic tension eventually culminates in the two of them kissing in Basic Straining, with her displaying a more relaxed attitude towards the competition from Duncan's influence. However, any hope of the two competing alongside each other for the rest of the season was dashed when Courtney is voted off in that same episode, due to Harold tampering with the votes, as revenge for Duncan's bullying when he sees the two kissing. Signs of Duncan and Courtney having feelings for each other continue to be shown in many episodes after Courtney's elimination and well into the second season.
Courtney initially did not qualify for Total Drama Action while Duncan does. During Courtney's absence Duncan become good friends with Gwen, but Courtney assume that he is cheating on her. Duncan did show that he misses Courtney as he slept with a picture of her under his pillow and thinks of her when he is stargazing with Gwen. When Courtney returns in Ocean's Eight - Or Nine, the two of them put their relationship aside and become enemies again as they were on different teams. This is also because of Duncan is angry for the unfair advantages Courtney has while Courtney is angry of his and Gwen's friendship. Despite this, Duncan is unable to hold his feelings for her back and he lost to her in several challenges despite his great achievements before her return. Eventually, the two of them made up in Top Dog, but Courtney also imposed a set of overbearing rules on their relationship, expecting Duncan to completely memorize and follow them if they ever want to have a serious relationship. Because of this, Duncan voted Courtney off and they broke up. However, after the season finale, the two of them reconciled as a couple. They were shown in Celebrity Manhunt's Total Drama Action Reunion Special to have broken up again, but they got back together by the end of the episode after a kiss on the bus.
When season three starts, Duncan and Courtney are still a couple although Duncan is slowly losing interest in her due to her bossiness and control over him. At the same time, he starts to develop romantic interest on Gwen. Courtney is also angry at Gwen, thinking she has a crush on Duncan. The argument between both girls is what cause Duncan to quit the season. Despite these initial feelings of distrust, Gwen and Courtney eventually develop a friendship in the absence of Duncan, who quit the season in the first episode. During his absence, Courtney constantly shows signs of missing Duncan, but tries not to let it affect her competitiveness. However, Duncan eventually returns to the competition in I See London..., and Courtney's worst fears are realized when Gwen and Duncan share a kiss at the end of that episode. Courtney remains unaware of the kiss until the end of Greece's Pieces, when Tyler is forced by Alejandro to tell everyone about it, since he was the one who accidentally witnessed the event in the confessional. Courtney is devastated and heartbroken by this news, and it destroys her friendship with Gwen, as well as her relationship with Duncan. Courtney officially breaks up with Duncan in The EX-Files, after she dumps a bowl of spaghetti on his head and kicks him in the groin for cheating on her. He and Gwen will then start a relationship in the same episode. After Courtney is able to eliminate Gwen in Picnic at Hanging Dork, Duncan's hatred for Courtney intensifies and the two of them argue even after Gwen's elimination. Courtney also moves on from her relationship with Duncan, and starts to be attracted to Alejandro and now to Scott. From here on, the two of them return to being fierce enemies.
Duncan and Courtney start out as enemies, as Courtney quickly annoys her team with her militant leadership and frequent mentioning of her C.I.T. experience. Their first interaction is at the beginning of the challenge, when their team is chosen to jump off the cliff first. As they are deciding who will go first within their team, Duncan says "ladies first" while looking at Courtney. During the construction of the hot tub, Duncan continues getting on Courtney's case by nicknaming her a "cyclops" due to her swollen eye from a bug bite. Because she and DJ refuse to jump off the cliff for the first challenge, they are forced to wear chicken hats for the rest of the day; their ineptitude plays a large role in the Killer Bass team ultimately losing the first challenge and having to send someone home that night. Duncan however personally suggests kicking off Courtney, finding DJ's strength and kindness to be more of an asset than Courtney's CIT experience.
Since Duncan was exhausted from the previous episode's challenge, the Awake-A-Thon, he refused to participate for most of the challenge. Courtney is one of the few who initially chews Harold out regarding Duncan's condition for most of the episode, showing concern for him. However, the Bass were put in a tight spot in a best three out of five game and already had two losses on their end. Courtney suggested they needed someone mean and fierce enough to give the team the strength to win, at which point everyone looked at the sleeping Duncan.
Courtney was the least afraid to wake Duncan up, as Duncan had made a death threat to the others before passing out on the bench. She collectively organized them all to awaken him with a stick, with Harold being used as a scapegoat towards his wrath. When the enraged Duncan woke up, Courtney came forward to explain their situation. When Duncan asked why he should help them, (calling Courtney "darling" in the process), Courtney responded by saying if he refused to participate in the game, she would personally guarantee that he would be the one voted off the island if their team lost again, sarcastically calling him "darling" in return. The threat was enough to force Duncan into playing, which won the Killer Bass the challenge.
Duncan and Courtney fought over leadership of the team during the Wilderness Survival Challenge. When the map and compass are given to Duncan, Courtney snatches them away almost instantly and shoots him a dirty look. While Courtney is pitching a tent, Duncan walks up to her and mockingly asks her what's for dinner, calling her "woman" in a derogatory manner. Courtney is disgusted with this, and refuses to dignify Duncan's question with a response.
Later on, Duncan scares the majority of his team with a horror story and a fake hook. Courtney especially is rattled, but pretends to reject her fear by yelling at Duncan. She later calls him vile and asks if his parents even like him, to which he casually responds that he doesn't know, as he hasn't asked them lately. He also calls her "Jumpy McChicken," which further aggravates Courtney. A sudden wolf cry frightens Courtney, and she automatically runs into Duncan's arms, which Geoff gives a thumbs-up towards.
While the team sleeps in their tent, Bridgette has to leave briefly to urinate. Being clumsy in nature, she accidentally kicks up an ember from their bonfire onto the tent after being blinded by a bat, which instantly incinerates their tent and leaves the Killer Bass with no shelter to sleep under. Courtney makes a big deal out of it, but Duncan tries to calm her down, saying it was no big deal and things were cool. Courtney shouts back that things could not possibly get worse, but right after saying that, it begins to rain. Courtney screams in frustration while Duncan smirks at her. The Killer Bass are forced to endure the thunderstorm with a mere leaf as shelter. By morning, it is revealed that Courtney had subconsciously cuddled with Duncan in her sleep. When she wakes up, she is disgusted by what has happened. Courtney blames Duncan for it, but Duncan casually says he made no moves whatsoever, and all of the cuddling was her doing. In the confessional, Courtney states that since she was not conscious at the time of the "alleged cuddling," it should not be counted as making a move on Duncan, and pretends it never happened.The Killer Bass lost the challenge because Katie and Sadie were separated from the group and arrived after everyone else did. After the campfire ceremony, Courtney is sitting outside her cabin, swatting away the gnats and mosquitoes, until Duncan shows up and sits next to her. She angrily asks what he wants, and Duncan apologizes for scaring her with the horror story from the previous night. Courtney argues that she was not scared at all, but screams in terror when Duncan brings out his fake hook out of nowhere again, proving her wrong. Enraged, she stands up and stomps off, telling Duncan that she hates him. However, an amused Duncan tells the audience that he is certain that she doesn't mean what she says.
Starting off from the point where the last episode ended, the Gopher team arrives with gifts from their Tuck Shop party. This inadvertently spurs a conversation between both teams about their greatest fears. Courtney adamantly claims that she isn't afraid of anything, but no one - especially Duncan - believes her, as he reminds her about how badly he scared her last night. Courtney is quick to tell him to shut up, but also makes fun of Duncan when he reveals his worst fear: Céline Dion music store standees.The challenge of this episode happens to be based on every camper facing his or her worst fear, earning points for every individual fear conquered. When Duncan has to face his fear by hugging an actual standee of Céline Dion, Courtney suddenly acts empathetic towards him and takes his hand, sweetly saying it's okay if he can't do it (which greatly contrasts to previous incidents in the episode where Courtney pressures her other teammates, especially DJ, to conquer their fear to earn them the win). This assurance seems to greatly aid Duncan as he manages to conquer his fear and hug the standee. Courtney cheers and calls Duncan awesome. Duncan is amazed that he managed to pull it off while Courtney hugs him, only to quickly let go when the others gather around to congratulate him. It is eventually revealed that Courtney does indeed have a phobia: green jelly. Duncan chastises Courtney for it, and she is quick to tell him to shut up and explaining that it's only because green jelly is like jiggly, sugary snot. The Killer Bass are desperate for Courtney to conquer her fear, as it is the only way for them to win the challenge. While Courtney is climbing the ladder to dive into the green jelly, Duncan yells out, "That's it! Keep climbin'!" However, returning the favor from earlier, Duncan tells Courtney that it's okay if she can't do it, even though it'll result in a loss for their team and an elimination. Courtney is unable to face her fear, causing the Killer Bass to lose the challenge.
Duncan and Courtney are designated as deer to be hunted for this episode's challenge, and they spend most of the episode apart from each other. Near the end of the episode, Courtney crosses paths with Duncan on her way back to Camp Wawanakwa. Following an argument about which way the campsite was, Duncan and Courtney's antler caps tangle together when they pass by each other making a heart shape in the antlers, foreshadowing the relationship. The two struggle to break free from each others' grasp (in a confessional, Duncan admits that he actually liked it and points out that they did not simply remove the antler hats because he suspected Courtney would tattle to Chris and have their team disqualified), but they remain stuck. After giving up, Courtney angrily asks what they're supposed to do next and Duncan asks if she wants to make out with him. Courtney's face suddenly goes blank, suggesting her "answer" as a no-go.
The two eventually make it back to camp, still attached to each other, where everyone is waiting. After Gwen and Owen make comments on the compromising position between the two, Duncan slyly claims that the girl can't keep her antlers off him. In response, Courtney kicks him in the crotch. Due to the fact that they were stuck together at the time, Duncan is especially reeling in pain since he can't even bend over.
During the cooking challenge, Duncan and Courtney are paired for making the dessert of their Italian-themed three-course dinner: the cannoli. Duncan happily complies while looking suggestively at Courtney, while Courtney refuses to participate if she has to work with Duncan. Geoff, the Head Chef, tries to appeal to Courtney as he and Duncan give her an innocent, pleading look, which causes Courtney to reluctantly accept. However, the confessional stalls reveal Courtney almost obsessively complaining about Duncan and all of his traits that annoy her. She talks about him so much that the production staff actually fast-forward through bits of her ranting. What can be gleaned from her tirade is that she finds him unmotivated, hates that he never washes his hands, finds him to be a delusional poser, and hates the style of his hair.
After a couple of minor insults while making the pastry and custard, Duncan tells Courtney that she would be much more fun to be with if she weren't so uptight. Courtney argues that she is the most easy-going person she knows. Duncan mocks her and sprays custard on her face. She is taken aback, but then responds by throwing the whole bowl of custard over his head, covering his face. She giggles and triumphantly wipes a fingertip of custard from Duncan's face, licks it off, and smirks at his "defeat." Duncan doesn't retaliate; he simply stares at her, annoyed.
Following the argument, another series of confessionals come up with Duncan admitting that Courtney creases him... but surprisingly, he is attracted to that trait of hers. Another Courtney confessional follows, this time about Courtney ranting about the unlikelihood of the two ever becoming a couple. She is interrupted by Leshawna from outside, who wishes to vent her own feelings (showing that Courtney has been hogging the confessional stall for most of the episode), but Courtney continues to say that a relationship with Duncan and her won't happen.
Afterward, it is time for both teams to have their courses judged by Chris. As he samples the cannoli from Duncan and Courtney, Courtney is shown to be a little anxious as she awaits the results. Duncan's eyes do not leave the judging table, but he puts a reassuring hand over Courtney's shoulder (somewhat similar to Courtney's reassuring gestures in Phobia Factor), after which the two look at each other and smile. The two are downtrodden when Chris gives them a mediocre grade of six out of ten points. However, the Killer Bass ultimately win the challenge, Duncan wraps his arms around Courtney's back and lifts her up to celebrate with the others. Courtney goes along with it for a short time, but then demands Duncan to put her down. Embarrassed by his sudden actions, Duncan does so.
As the campers are having breakfast, Duncan steals an extra coffee mug while getting a drink. Just as he turns around, Courtney is there, watching him like a hawk and tells him that she saw the whole thing. She asks how he could just go about stealing mugs; Duncan explains that they were cool-looking and he simply wanted one for himself. Courtney warns Duncan that he might get kicked off the island for stealing camp property. Flattered, Duncan tells Courtney that he didn't know she cared so much for his welfare. Courtney denies that, saying she simply does not want her team to lose another member. Duncan brushes it off, saying he knows she really likes him deep down. Courtney simply walks away then, too frustrated to argue with him any longer.
When Chris introduces the trust challenge for the day, he mentions the rivalries in the Screaming Gophers team, as well as something strange going on with certain Killer Bass campers. Duncan elbows Courtney suggestively (believing Chris is talking about the two of them), which results in her pushing him down.
Courtney is knocked unconscious during the Blind William Tell challenge when Sadie repeatedly and unintentionally pelts her with crab apples. She wakes up in the infirmary tent and spots Duncan luring over a rabbit with a carrot. She wonders what Duncan's up to and investigates. Eventually, Courtney learns that Duncan was finding a new rabbit for DJ, whose first rabbit was eaten alive by a snake while it was under Geoff's care.
Courtney was witness to the whole thing and despite her initial belief, she realized that Duncan was actually a nice guy deep down and told him so. Duncan tried to brush it off, claiming the rabbit followed him, but broke down when Courtney cornered him with the truth that he could not deny. While he didn't say why, he admitted to it and made Courtney promise not to tell anyone about what he did, not wanting the other campers to get the idea that he was a nice guy. Courtney assured Duncan that his secret was safe with her, though later on, she would end up telling other people about it anyway.Chef Hatchet's grueling challenges. Again, Duncan teases Courtney by saying she must really like him to be so insistent on him following the rules, but Courtney uses the same rebuttal as before: she simply doesn't want her team to lose the challenge. When Duncan and the other guys prank Harold, she calls them immature, but Duncan blows it off by accusing Courtney that she actually likes him and everyone knows. He says that he might even let her kiss him if she wants. Due to this, Courtney comes close to spilling Duncan's secret from the previous episode, but takes it back and assures Duncan's peers that he's every bit as nasty and mean as he wants others to believe.
After the essay challenge, Duncan comments that Chef "missed a spot" when wiping saliva from his neck. Chef threatens Duncan for teasing authority, and at this Courtney quickly grabs Duncan's shoulders and pulls him away, denying Chef's offer to have him run laps around camp. She takes Duncan aside, asking him what he was trying to do. Duncan shoots back that he "Didn't know she cared." Courtney angrily replies that she doesn't, and again uses the worn out excuse of "I don't want to lose another challenge." She kindly asks him to stop being such a mistake for his team, and walks away. Duncan doesn't take note to this, and smiles, again claiming that Courtney wants him. Geoff then agrees with him.
During the obstacle course challenge, Duncan angers Chef to the point where Duncan is punished harshly: solitary confinement in the boathouse. The others are fearful, but Duncan doesn't understand what the big deal is until he's actually inside, surrounded by several sharp and spooky objects. While eating her meal, Courtney becomes concerned for Duncan and decides to go check on him. Geoff accuses Courtney of liking him, which she vehemently disagrees with. She lists all of his annoying qualities in an attempt to prove to Geoff that she can't stand Duncan, but after she leaves to go check on him, Geoff is shown in the confessional stall, still believing that Courtney is attracted to Duncan.
Courtney arrives at the boathouse with a bowl of mush for Duncan to eat, saying even pigs deserve a meal after Duncan asks if she's come to claim the kiss. Duncan respectfully declines the offer while Courtney explains that it's all Chef would serve them. She then asks Duncan why he insists on egging on Chef when he knows he'll only get in trouble. Duncan rebuts by asking Courtney why she has to be so uptight all the time, accusing her of always following the rules. Courtney counters by accusing Duncan of always having to break the rules, but he says he only breaks the rules he chooses to. Courtney admits that she does follow the rules and asks Duncan if he sees her as a loser because of that. Duncan gives her a simple "maybe" answer (which irritates her), then asks Courtney why she does follow the rules all the time. Angrily, Courtney explains that not following the rules results in suffering consequences such as being locked in solitary confinement in a fish cabin. Duncan notes that he is in the fish cabin, but with her. They both smile suggestively at each other as Duncan asks Courtney if she'd like to ditch the boathouse with him to get some real food. The exhausted and starved Courtney says she would love to, but brings up the fact that Chef would never give it to them. Duncan points out that that's the flaw with her thinking, and she shouldn't ask for it in the first place. Courtney asks if Duncan has any of Chef's food, which he says he doesn't, but happens to know where to find some. He warns Courtney that it will involve breaking some rules, but after a moment of consideration, Courtney agrees to work with Duncan.
A new side of Courtney is awakened when they successfully sneak into Chef's refrigerator and steal an abundance of food for themselves and all of the other campers to share. To stick it to Chef, Courtney leaves behind a dead fish in the fridge after gathering the food, considering it a little "present" from the Killer Bass. Impressed with her methods, Duncan compliments her and they both manage to sneak out back to their cabins with an abundance of food, bringing relief and sustenance to all of their fellow contestants from both teams. Caught up in the moment, Courtney eats too much and ends up vomiting. Duncan is witness to this, noticing the "Princess" has a "dark side" to her. Courtney admits to Duncan that doing something bad was so invigorating for her that she just wanted more and more. Duncan brings up the kiss offer again, saying that would be bad. Courtney teases Duncan by saying he still isn't her type and hopes he will enjoy prison, but after that, Courtney suddenly steals a kiss from Duncan, which Duncan happily complies to.
Duncan's fellow men congratulate him on finally winning Courtney over, with Duncan casually saying he knew all along that Courtney wanted him. Harold was also witness to this scene and became enraged, but was interrupted by Chef's announcement of the next level of training beginning in a few hours. The final test was to hang upside-down from a tree as long as one possibly could. As Chef began to describe the pain and torment the body goes through after being held upside-down for so long, Duncan falls out of the tree in a daze, making Courtney call for him out of concern. However, Bridgette checked on him and he turned out to be alright. Soon after, Courtney started to laugh hysterically at the sight of Owen falling on Heather, and fell out of the tree as she was unable to control her laughter. She tells Chef to take a chill pill before joining Duncan arm-in-arm, shocking everyone else, but her romantic interest. However, when it came down to the final two, Geoff is unable to outlast Gwen, making the Killer Bass the losers of the night.
At the Campfire Ceremony, Courtney and Duncan look at each other with adoring eyes as Chris explains the elimination progress and hands out the marshmallows. The final two are Harold and Courtney; Courtney looks rather confident, but is outraged when the last marshmallow goes to Harold instead of her. As Harold claims it, Duncan, Geoff, and DJ look on, dumbfounded. All three of them did not vote Courtney off, and Courtney did not vote for herself (resulting in at least four out of six votes in her favor), making it mathematically impossible for Courtney to be eliminated. Duncan and the others try to appeal, but Chris and Chef ignore it and toss Courtney onto the Boat of Losers. Duncan angrily complains that the situation sucks, but manages to throw a present over to Courtney before the boat takes her too far away. It's a carved wooden skull, which Courtney finds weird and creepy. Regardless, she loves it, and waves goodbye to Duncan; she promises she would never forget him.
At the end of the episode, it was revealed that Harold tampered with the votes to get back at Duncan, who had pranked and tormented him several times throughout the series. He figured the best way to get back at Duncan would be to mess with his love life. Duncan himself would not find out who caused Courtney's elimination until much later on.
Though most campers voted Eva off the island right after her surprise return, Duncan was one of the few who did not. He voted for Heather instead, suspecting her being the one behind Courtney's elimination. He gives her a shout-out afterward, saying he misses her and calls her "babe." However, he pinned the blame on the wrong person, as Heather had nothing to do with Courtney's elimination, both in being on the other team and not doing any intentional manipulation of the game to eliminate her.
The final six campers are paired up in three groups of two and handcuffed together. Duncan is handcuffed to Leshawna, and the two do not mesh very well. Leshawna eventually corners Duncan about his hidden softer side, which Duncan vehemently denies. Leshawna brings up his relationship with Courtney, which Duncan scoffs at, saying that meant nothing because he simply thinks she's hot. However, Leshawna mentions that Courtney told her about the situation with DJ's bunny (something Courtney originally promised to keep a secret), leaving Duncan with no choice, but to explain his reasoning and his softer side.
During the last challenge, the campers had to make a totem pole using carved wooden heads of all the past losers from the beginning to the present day and stack them in order from the first camper eliminated to the most recent camper eliminated. Duncan panics when Chris takes a wooden head of Courtney, which Duncan carved a heart with "D+C" inscribed within it on the back of the wooden head. Chris makes fun of Duncan for it and calls him soft, but Leshawna knocks out Chris with another wooden head (which was shown to be Sadie's wooden head) in Duncan's defense, saying there's no need to be tough all the time.
Courtney admits to the cameramen that she hoped Duncan would win the competition and that she really likes him; something that everyone else overhears and teases Courtney for, considering that she went so long denying her feelings for him. Courtney also forces Harold to vote for Duncan to win (though it is obvious he doesn't plan on doing so). Harold says "I vote for Duncan. Not!"
Duncan and Courtney side with Owen during the final competition and sit next to each other. They, along with a couple of other Owen-supporters, follow Gwen and Owen as they race through highly-dangerous obstacles. Duncan compliments Chris on his idea for Owen and Gwen having to fight off angry eagle parents while carrying eagle eggs from a steep cliff, and Courtney asks why he likes it so much. In the confessional stall, she says that boys are stupid to like death and bodily functions, but then confesses that she thinks danger is hot, and they kiss after Courtney tells Duncan that he still isn't her type. Duncan retorts by telling Courtney that she makes him sick before they kiss once more.
During the celebration at Playa Des Losers, Courtney is embarrassed at Duncan's horrible dancing moves and tells him to stop. Duncan wonders why she's in such a bad mood, and Courtney explains how she lost the competition and the lawsuit she filed against the producers for unfair termination of competition and now just wants to go home to study for her LSATs and work her class president campaign. Duncan calls her a downer and tells her to relax since the crazy adventure is almost over, and Courtney angrily yells that she is happy (though she certainly doesn't look happy).
Suddenly, Chris comes by with an offer for all campers to compete for a million dollars (ten times the amount Owen had won in the previous episode) if Owen would forfeit his prize money. He does so, and the game is on. Courtney's mood greatly improves, saying that things just got interesting again. Courtney teams up with Duncan to win the million dollars and split it 50/50. Pumped up and enthusiastic, Courtney pulls Duncan over to her and kisses him deeply. Duncan is amazed with Courtney's revived spirit and happily goes along with her. Throughout the episode, they call each other pet names such as "honey" and "hot stuff."
Unfortunately for Duncan, Courtney is shown to be more interested in winning the money than anything else, since she is quick to abandon Duncan after he injures his ankle after tripping over a rock, using the excuse that she can't have him slowing her down (even though he just wrestled an alligator for her moments ago) even if he does mean the world to her. After she runs off, Noah appears, metaphorically kicking Duncan while he's down as he mocks him due to Courtney's betrayal. An enraged Duncan is still able to rip Noah's pants off in retaliation. As Courtney ran off with the money, Izzy lands on her out of nowhere and takes the money. Courtney screams and runs after Izzy and her teammates, declaring that no one will steal the money that she stole, prompting Duncan to casually remark that he "loves that woman" and seems not offended that she left him.
Later, Courtney steals the case in a hot air balloon and sees Duncan fending off a moose that attempted to chase him. Admiring his bravery, she cheers him on, but Duncan responded that he would come for her next in an almost-threatening and vengeful tone. By the end of the episode, a fourteen-way tie is made after a shark eats the suitcase with the money. The fourteen-campers in the tie are the ones who get to participate in the show's second season. However, while Duncan qualified, Courtney did not.
In the Total Drama Action version of the opening sequence, Courtney first scowls at Duncan for shooting Harold with seagulls, but then makes out with him, and pulls away grinning deviously at Harold's misfortune while Duncan appears both happy and surprised.
It is revealed by Gwen that Duncan keeps a picture of Courtney under his pillow, strongly indicating that he still has feelings for her.
Duncan mentions that the reason he continues to relentlessly pick on Harold this season is because Harold is the reason Courtney was sent home in the last season, meaning Duncan has finally found out why Courtney was voted off in Basic Straining, and hates Harold because of that. He also says she has beautiful brown hair and that she can "tear anybody limb from limb."
Courtney grows jealous when Trent reveals that Gwen and Duncan have been hanging out. Trent has had similar feelings, directing his anger at Duncan, but at this point, Courtney seems to also be angry at Duncan rather than Gwen. However, this quickly changes by the next Aftermath.
Courtney was shown to be booing and glaring at Gwen from the moment she enters the stage, obviously angry at her for hanging out with Duncan. She shows her anger the most when Gwen pointed out that Duncan didn't vote her off; Courtney immediately stands up and yells that the only reason Duncan didn't vote Gwen off was because Gwen had her "goth girl hooks" into him. Gwen then explained that her and Duncan are only friends. Geoff then showed a never before seen clip of Duncan and Gwen looking at the stars. Gwen tells Duncan that she sees a constellation that looks like Harold's butt, but Duncan is completely oblivious to what she said. Duncan just sits there with a dreamy look on his face and then asks Gwen if she thinks Courtney is looking at the stars. Geoff pauses the clip and Courtney has a happy look on her face and Gwen tells her that Duncan always thinks about her. Geoff then resumes playing the clip. Then in the clip, Gwen comments Duncan's question and the two wrestle. They both fall onto the ground, Duncan landing on top of her, and both give each other a blank stare. Geoff points out how close Gwen and Duncan's lips are from each other. Courtney gives Gwen an angry look and says she's calling her lawyer. Notably, throughout all of Gwen's remarks about her and Duncan being just friends, and everything else she told Courtney, the anvil, which was a part of the game "Truth Or Anvil" in which the anvil would fall if someone told a lie, never fell. This implies that everything Gwen said was truthful.
Courtney returned in this episode due to a successful lawsuit against the producers. When the Gaffers got to the bank, Duncan commented on the teller (who was Courtney in disguise), saying she had a "great set of legs" and "lovely hands." After asking him if he needed anything else, Courtney took off her blonde wig, which made Duncan faint upon seeing her, and was in awe when Chris announced that Courtney was back in the game.
Chris gives her the option of who deserved to win the bank money as first prize, and she said that the Gaffers (preferably Duncan) deserved it for getting to the bank first and happily gave Duncan the money. Duncan seemed extremely nervous when she gave it to him.
He nervously said in a squeaky voice "Thank you," while he made a nervous face (see picture to the left). While assembling their go-cart, Duncan stared at Courtney constantly, and he ended up hurting his hand since he wasn't paying attention to what he was doing. When the Gaffers completed their kart and started to drive off, Duncan stopped in front of Courtney and teased her by saying, "Hey Courtney, maybe you'll get to see more than just the back of me when the teams merge!" Courtney, who was frustrated with her team for not working on the challenge, says that she would take it at this point. Heather referred to Duncan as "Casanova" when he was teasing Courtney.
In this episode, despite the fact that they still care about each other, Duncan and Courtney seem to have developed a competitive/hateful attitude toward each other. In the beginning of the episode, while Justin was fixing his hair, Duncan mentions that Courtney has beautiful hair but he quickly tries to cover it up by saying that it wasn't that he noticed and it was back when he used to care (though it's obvious he still does). After Chris tells the castmates about "Courtney's rules" Duncan calls Courtney a spoiled princess and says she didn't waste her time hooking herself up. Courtney retorts, saying he didn't waste any time hooking up with Gwen while she was gone. He teases her back saying he was touched that she was "obviously still hot" for him, but his relationships were none of her business. She snaps back, saying they were on television and it was everyone's business. Duncan continues to tease her, asking her if she didn't think she could win the contest fair and square and playfully points his finger at her. Courtney then smacks his hand away, saying she could kick his two-timing butt with her eyes closed and both hands tied behind her back. Duncan then snaps and says that it would be hard to eat lobster that way, and then they start to growl at each other with their teeth bared.
After Chris explains the theme of the challenge, he tells them they'll have to wear loin cloths. Courtney smirks at Duncan and tells him that he'll look perfect since he was "already a total Neanderthal," and walks away. Duncan then looks like he was about to say something back, but a loin cloth was thrown in his face before he could say anything.
During the first challenge, Courtney brings up her C.I.T. experience again, and Duncan calls her a drama queen. Courtney first asks him why, and then angrily adds on if it's because she thinks Duncan's a dog for hooking up with Gwen. Duncan is then shown in the confessional stating that he didn't hook up with Gwen and that having Courtney back reminded him how much she drives him crazy. He then repeats that she drives him crazy, but with a dreamy look on his face and a tone of adoration in his voice. Then Courtney is shown in the confessional, saying that she watches the show and knows what she saw between Duncan and Gwen, and ending her confession stating that nothing gets past her.
Not long afterward, the fire starting challenge begins. Heather encourages Duncan on, and he starts hitting the flints together. Beth and Lindsay start to cheer on Courtney, and she follows Duncan's actions with her flints, giving him a glare. Chris then comments that he "loves it when sparks fly." Duncan smacks the flints together again and then glares at Courtney, while she does the same. While Courtney continues to smack the flints together, Duncan secretly takes out his lighter, and flames rise in the Gaffers pit. Courtney then looks in surprise as the Gaffers cheer by their fire. Duncan then looks towards the Grips and shouts, "I make fire!" and thumps his fists against his chest in a cocky sort of way.
Before the second challenge begins, Courtney mocks Duncan, saying in a sarcastic tone that it was a big surprise that he cheated. He just smiled at her and said that he had many more for her, and then calls her "sweetheart," to which she growled at.
Duncan and Courtney are then seen on top of the same column, with Courtney holding onto Duncan to not lose her balance. Duncan laughs and tells her to stop trying to make out with him. Courtney just glares at him and tells him that only thing he'll be kissing was the end of her bone, and threatens it in his face. Chris then sounds the horn, and the two raise their bones to start the fight. However, they end up leaning back too far and start to fall backwards. Courtney grabs Duncan's wrist to re-gain balance, which causes them to hoist back up so fast, they accidentally kiss each other. Courtney has a look of shock on her face, while Duncan happily shouts "That's the stuff!”. Duncan is then seen in the confessional, and he says that it was like there were two Courtney's up there. The nut-job he wanted to knock into the tar pit, and the "hottie in the fur bikini." Then Courtney is shown in the confessional, and she admits that Duncan has this "primal, animal magnetism," but he also makes her want to hit him where it hurts.
Courtney and Duncan are then seen on the column, right where they left off. Courtney is giving Duncan an angry glare, while he looks at her with wide eyes. The mood then suddenly lightens, and they smile at each other. They start to lean in for another kiss, when Courtney suddenly screams, raises her bone, and hits Duncan hard in his groin. He shouts in pain, and Courtney lets go of his wrist as he falls into the tar pit below with a look of satisfaction on her face.
At the end of the episode Courtney is shown in the confessional again with a plate of lobster, and she simply states Duncan had what was coming to him as she takes a bite of her dish. Duncan is then shown in the confessional right afterward. He squeals in pain again and says in a shaky voice, "Why do they always go for the kiwis? Why?!".
When Harold and Lindsay were up against each other in a round of boxing, Lindsay started to eat Harold's glove (which was made of marshmallow). Courtney shouts at her to not eat it and encourages her to "get dirtier." She then hears Duncan chuckle and then sees him gazing at her with dreamy eyes. When she questions him, he happily replies that he likes it when she talks like that.
Later, everyone is able to see what Leshawna secretly said about all of the contestants while she was on her spa day with Leshaniqua on Courtney's PDA. In the video, after Leshawna first insults Heather, Lindsay and Justin, she then said that Duncan acted like a tough guy, but when Courtney was there, she "practically dragged him by his eyebrow ring," and then continues to insult the others. After hearing those words, both Duncan and Courtney become angered at Leshawna, along with the other contestants when they finally know what she really thought about all of them.
Later, in the third challenge, Chris announces that Duncan and Courtney have to wrestle in a ball pit. It then shows Courtney in the confessional, and she happily says her heart "can't be swayed by just any tattooed bad boy oozing danger out of every pore," but then she gets serious and says she's a "fit and well-coiffed little package of pure competition." This confessional makes it even more obvious that she still has strong feelings for Duncan and his bad boy charms, but won't admit it, and definitely won't let it get in the way of the competition. Then we see Duncan in the confessional, and said that Courtney was a "fit, well-coiffed little package" but wasn't going to go there, even if he could, reminding the audience of Gwen and Trent's relationship, and how it got ugly between them when they were stuck on opposite teams, meaning he doesn't want what wrecked Gwen and Trent's relationship to happen to him and Courtney as well.
Before the challenge starts, Duncan repeats to himself to "just compete." Chris then sounds the horn and the two dive into the ball pit. They come back up to the surface with Courtney on Duncan's back with her arms around his head, and she teases him by asking him if he couldn't swim. Duncan then sees something sticking out of a pile of balls and mistakes it for a shark, but Courtney picks it up and reveals it to be a dirty diaper. She then sticks it in his mouth, shouts "C'mon tough man!" and they fall back into the pit while the other contestants laugh on the sidelines. Duncan then comes back up, spits out the diaper, and states that there was no more "Mr. Nice Guy," and Courtney kicks him in the chest and tackles him down again, and the others gasp. Courtney is then seen on top of Duncan on a pile of balls.
He reminds himself of Gwen and Trent in a mutter, and pushes Courtney off of him. She lands on the other side of the pit and he dives after her, while their teammates gasp again. Duncan comes back up with a baby bottle in his hand, and then asks if there was an entire day care center in there. Right after he finishes his sentence, he then accidentally picks up some little kid from the bottom of the pit who calls him "Mama" and is quickly taken away by Chef Hatchet. Courtney then tackles Duncan once again, and pulls him up with her arms around his neck. He then painfully cries out "Uncle!" in defeat, and the Grips cheer for Courtney and her win. She then stands, takes a few deep breathes, and cheerfully shouts in victory at Duncan. Duncan is then seen in the confessional again, saying that the little kid called him "Mama" and it threw is A-game. A crew member is heard laughing the background, and Duncan then threatens him by telling him to laugh to his face.
The Grips later won the tie-breaking challenge with their Chris kiss-up cheer, and the Gaffers are pronounced the losers of the day. At the Gilded Chris ceremony, Chris pokes fun at Duncan for losing to a girl in a match of wrestling. Duncan then states that she wasn't "a girl," she was Courtney, and it was a whole other thing.
The episode begins with the contestants in front of the trailers. When Lindsay tried going into the girls' trailer, she was denied access inside, and was sent into a pit below. Duncan runs to the side of the pit in surprise, and is suddenly hit with a tranquilizer dart and faints into the pit. Courtney immediately rushed to his side in worry, and called him by the affectionate term, "Dunky." Harold and Leshawna both notice this as odd. After all the contestants were dragged into a hidden cave, Duncan is seen checking Courtney out. Later, when Courtney was finding a way out of the cave using the GPS that was programmed into her PDA, Duncan indirectly says that he would follow her despite Leshawna's warning to him that it would lead to "heartbreak and tears on [his] pillow."
The first challenge of the day was to reach a case with a small bag inside without getting hit by the many lasers guarding it. Courtney amazed Duncan by using martial art skills to make her way through the lasers, saying that if he was a wolf he would howl; he decided to howl, despite. When Courtney was seen crouching to slide herself under the lasers, Duncan seemed to be staring at her butt, moving his eyebrows and smiling mischievously. When Courtney reached the case, Duncan gave her advice to getting it open by grabbing something and smashing the glass, while Harold told her to just stay away from it in case it was booby-trapped. Courtney then started to walk away, but then turned and started running towards the case and broke it open with a karate-kick, causing the other contestants' jaws to drop in surprise. Duncan is then seen in the confessional saying that nothing grips his wheel more than "a chick with a furious, spin-heel, flying jump kick." He then says that after her mixed martial arts display, Courtney shot way up on his "you're all right" meter, ending his confessional with a flirty wink.
After Courtney reveals the bag's contents, a grappling hook gun and pliers, Leshawna remembers that Chris mentioned about a building that's about to blow. Chris suddenly appears on the monitor and starts a countdown. As the contestants start to scream and hug each other, Courtney immediately hugs Duncan in fear while Duncan looks at her with a worried expression. Chris then started to laugh, saying it was just a joke. Duncan starts to complain at him, when Courtney notices she still had her arms around Duncan. She then quickly lets go of him and pushes him over. Courtney is then showed in the confessional saying that, for the record, what she gave Duncan would properly be classified as a "pity hug," saying that he was clearly scared out of his mind and would've died of fright if she hadn't wrapped her arms around him. Her tone suddenly becomes more dreamy-like, and she mentions how his "little heart was beating so fast," putting her hands to her own heart, closing her eyes and smiling happily. She then snaps herself out of it, calling it a pity hug once more, plain and simple. The confessional then shows Duncan, and he says that Courtney was this close to begging him to take her back.
When Chris begins another countdown, Courtney refused to let Duncan, as well as the others, escape with her unless they split the prize money with her if they won the competition. Courtney later drops the deal so she could join the others in a tomato juice bath at the end of the episode. When Justin asked how everyone was going to escape on only one line, Courtney grabs Harold's belt and tells Duncan to grab on. He replies that he "thought she'd never ask." As the group is seen sliding down the line with Harold's belt, Duncan's arms are seen around Courtney's waist. When everyone reaches the end of the line, they fall to the ground. Duncan lands on his front side, and Courtney then lands on his back, her eyes tightly closed.
In the recap, Chris wonders if Duncan will win back Courtney. While trying to decide who they should vote off Justin mentions they should vote off Courtney since she is the biggest threat. Duncan then becomes a little worried, but then reminds the guys that Courtney has invincibility and they should vote off Leshawna. The girls wanted to vote off Duncan because he was strong and even though Courtney would never admit it, it would drive her crazy. Duncan visits Courtney when she is alone in the girl's cabin. He whistles and she comes to her window, seeming to be familiar with his call, indicating that this may have been an off-screen event occurring in Total Drama Island.
In the recap, Chris wonders if Duncan will finally hook up with Courtney. In the first scene, Duncan was hosting a biggest-burrito competition and he wonders if Courtney thinks he is a good host. When Courtney sings a brief ballad in the second challenge, Duncan is entranced and agrees with Justin calling her the "most beautiful girl ever." But then he gets mad when he realizes that Justin is falling for Courtney. Justin and Duncan try to be the "perfect prince" according to Courtney's song. Later, when Justin is flirting with Courtney, Duncan calls him "Sir Suck-Up" and Courtney says that he could learn from Justin that it's nice to get a compliment every once in a while.
When Courtney is "kidnapped" by Chef, she says she wanted Justin to rescue her. Duncan gets jealous and tries to give her a compliment, saying that he likes Courtney's face. Courtney, however, ignores him.
When Courtney is in the tower, she gives each knight an air-kiss (not to mention Courtney seemed less than enthusiastic about having to send Duncan an air kiss in the first place). Duncan stole Harold's kiss, and then Justin stole his. Duncan and Justin then compete again to rescue Courtney, but Justin wins by taking advantage of Harold. When Chris said Justin and Courtney couldn't kiss, Duncan is relieved. When Chris jokingly says that Duncan got eliminated, a distressed Courtney yells at him to tell him to change the votes; but Chris then reveals that it was all just a joke and that Justin got eliminated. When Duncan saw how nervous Courtney got upon his phony elimination, his interest for her grows. Courtney then states in the confessional that she was distressed because she wanted to get Justin voted off, not because she was sad that Duncan almost got eliminated, even though her body language says otherwise.
After finding a flash drive in Harold's breakfast Duncan took Courtney's PDA. Courtney protested but Duncan asked her if she wanted to win. Duncan was amazed with Courtney's deductive skills when she found Chris in the safe. In this episode, Courtney openly flirts with Duncan twice; however, she does so mostly to take advantage of him for the sake of winning the challenge for herself. The first time she did it was to get a sample of his DNA by treating Duncan, which she did by treating him to a steak dinner and stroking his hair (much to his delight). The second time she did it was to get him to climb over the top of the train for the second part of the challenge, which she did by cooing words of encouragement into his ear. He smirked at her after the second time though, apparently impressed at her coaxing skills; Courtney subsequently acknowledges that she knows she's "good" at it.
Later, Harold, Beth, and Lindsay think Duncan killed Chris on Courtney's behalf. When Duncan was handcuffed, Courtney was the only one to show concern. Lindsay ultimately wins the episode's challenge, and as her reward, she gets to enjoy a night out at the movies with a friend of her choice. In retaliation for Courtney's bossy attitude towards her, Lindsay chooses Duncan as her date for the movies in order to make Courtney jealous. When Lindsay chose Duncan, Courtney gasped in shock. Duncan noticed this and smirked deviously; the audience is left to presume that he willingly went along with Lindsay's plan, jumping at the opportunity to make Courtney jealous. Indeed, Lindsay's plan succeeded; in the confessional afterward, Courtney breaks down with nervousness, almost near tears, and feebly attempts to deny her feelings, a display which Beth enjoys watching. Ultimately, Courtney's worries were unnecessary, since the "date" was shown to go very awkwardly, with Duncan and Lindsay barely talking to each other.
After Lindsay comes into the girls' trailer singing, Courtney complains that she is singing the wrong lyrics to the song and continues to rant about how she picked Duncan to go to the movies with her as retaliation. Later, when they are given their guitar-playing challenge, Courtney and Duncan are left as the final two. Courtney plays skillfully, even behind her head, on her knees, and with her teeth, while Duncan only hits every other note and then smashes his guitar on the stage. Duncan ends up winning because Chris says Courtney tried too hard.After Courtney's complaints, Duncan tells her to "watch and learn, baby doll." Courtney responds by hitting him in the crotch with her guitar and emphasizes her reply with "baby doll." At the next challenge, the cast must compete in a paparazzi obstacle course. Courtney finishes her's first, and Duncan comes after her. From winning the first challenge, Duncan gets to start halfway. He smashes his way through the paparazzi, but stops to write his number on the cardboard groupie, which Courtney rolls her eyes at. Their third challenge is to trash a hotel room. Courtney goes wild and smashes her way through everything in sight, even hurling a dresser out the window and picking up a bed with Lindsay on it. Duncan makes a point to talk about it in the confessional, saying that "nothing sharpens his dog collar more than a girl with a ton of attitude." When Beth, Lindsay, Harold, and Owen meet to talk about who to eliminate, they all (excluding Owen) agree to vote off Duncan. Lindsay says that even though she'd deny it, Courtney would crack if he was eliminated. In the Gilded Chris Awards, Courtney sees how Harold was voting for Duncan, and she glares at him.
Courtney and Duncan don't interact much during this episode. During the training challenge, both try to put heavier and heavier weights on Harold and Beth to see who is the toughest trainer. Courtney does, however, spare Duncan from eating the food she and Beth had sabotaged while they were on kitchen duty for losing the first challenge. Also, they are seen glaring at each other during the kung-fu challenge while controlling both Beth's and Harold's robots. They struggled to push their trainees further in the competition, and Courtney ends up breaking her joystick, which lets Duncan claim the win.
During the first challenge, Courtney is jealous when Duncan gives his pillow to his pet spider, Scruffy, rather than give it to her; but by the last challenge, when Scruffy is accidentally crushed and killed by Harold, Courtney tries to console a heartbroken Duncan by patting him on the back and saying that Scruffy is "in a better place." She then adds that it is certainly a better place than the film lot. It is later revealed in the confessional that Courtney is happy that Scruffy is gone, because now, Duncan can focus more on someone with "less hairy legs" (meaning her), something which clearly shows her recomposing endearment for Duncan.
After Duncan went crazy from being in the woods too long, Courtney's kiss snapped him out of it. Duncan, irritated by the thirty-two page letter, and stating that he is not willing to give up a million dollars for her, votes Courtney off. Courtney tells Duncan that their relationship is over when she is being taken to the Lame-O-Sine. Before Owen is pushed into the Lame-O-Sine after her, Courtney could be heard calling Duncan a "moronic, back-stabbing, no good traitor."
When Beth mentioned at the beginning of the episode that she was everyone's friend, Duncan denied that she was Courtney's friend, proving that Duncan and Courtney have spoken about Courtney's feelings towards Beth off-camera.
Later in the episode, Beth and Duncan had to correctly answer a trivia question about Courtney in order to avoid the final challenge. Duncan was relieved, stating in the confessional that while he may not remember details about every castmate, he does know a lot about Courtney due to their history and their relationship. The question Chris posed to Beth was to say the name of Courtney's all-girl rock band that she first mentioned in a confessional back in Rock n' Rule. Beth was unable to answer the question, and instead launched into an emotionally-charged tirade against Courtney. Duncan subsequently gave the correct answer ("The Type-A Psychotic Crazies"). However, Chris tells Duncan that the question he answered was Beth's question. Duncan's question about Courtney was to tell what color she was thinking of at that very moment. Duncan, though indignant at the ridiculous question, took a shot at answering it anyway, and guessed the wrong color (blue). Courtney herself was then shown watching from the Aftermath studio, annoyed that he did not know that the color was burnt sienna. For a brief moment before she spoke, Courtney was smiling at Duncan's appearance on-screen, implying that she still held feelings for him and hoped that he would prove that he indeed does knows a lot about her.
Despite having broken up with him in Top Dog, Courtney is shown to be Duncan's biggest supporter in this episode, indicating that she still has feelings for him and wants him to do well. When Courtney suggests that the tie should be broken by an "unbiased" quiz she designed, she winks at Duncan, implying that she intended for the quiz to be biased towards him. When Beth and Duncan were competing in Harold's "Hole In The Wall" idea, Courtney was shown cheering for him. While he and Beth were answering Trent's question, Duncan states that he wouldn't be caught doing what some chick told him to do in the first place. As the crowd and peanut gallery laugh at him for the obvious falsehood of his statement (knowing of his history with Courtney), Courtney is seen glaring at him. When Chris was shown to be perplexed by Courtney's ink-splattered ballot, she glares at him for even questioning who she'd vote for, and Chris subsequently counts the ballot as a vote for Duncan. After Duncan won, Courtney ran up to him and hugged him, stating that they are rich. Duncan hesitates at first, saying he never said he'd share his money with her. However, Courtney then kisses him and tells him that "every king needs a queen"; Duncan is shown to be grinning dreamily following the kiss, and he eagerly complies to Courtney's suggestion, happy that he won the money and the girl as he stated that he wanted back in Top Dog. They proceed to make out as the episode ends.
In Beth's ending, Duncan offers a hand to a visibly disappointed Courtney sitting on the couch and asks her out to dinner. Courtney looks at his hand with a slight look of surprise, but then gives him a slight glare and then turns her head with her arms crossed and eyes closed, pouting; she then haughtily states that she doesn't "usually eat with losers." Duncan grins at this and says the same thing about her. She smiles and takes his hand, accepting his invitation. As they leave, they tease each other. Courtney pulls out her PDA and calls her lawyers, telling Duncan that the two of them need to work out a strategy with her lawyers and sue the show for "election fraud," since she believes that he should have won. Courtney grabs Duncan's hand and leads him out, while Duncan gives the camera a humorous look of resignation at the situation.
On the Celebrity Manhunt show, it is revealed that Duncan and Courtney continued to date following the conclusion of Total Drama Action. Their fame from the Total Drama reality series led to them being described as a celebrity "power couple" that the entertainment media dubbed "Duncney," with paparazzi following their every move. They even got matching heart tattoos on their arms, as well as a pet raccoon that they named Brittany. However, their personalities soon began to clash with each other once again, and they broke up following a particularly nasty fight over dinner at a fancy restaurant one night. A press conference was held with the two of them; Courtney kept ranting about all the disagreeable traits she found with Duncan (which seemed to mostly concern his eating habits), but Duncan declined to take part in the press conference and simply kept replying with "no comment." Josh, one of the Celebrity Manhunt hosts, subsequently revealed that Courtney is currently suing Duncan over custody of Brittany.
At the Gemmies, when Sierra questions them on the break-up, they simultaneously reply that their lawyers have advised them to decline comment at this time. Courtney is then shown to be astonished that Duncan acquired a lawyer of his own. When Courtney breaks the TV outside the awards show off its base in anger and tosses it away, Duncan is shown grinning and dreamily remarking on how much he "misses that girl." Later, as Courtney is driving the tour bus away from the bus containing the "Total Drama Dirtbags" cast, she and Duncan get into a heated argument about who should drive. However, they eventually stop arguing to stare into each other's eyes, and suddenly begin kissing, unable to deny their feelings for each other any longer. Unfortunately, since Courtney happened to be driving the bus at the time, the bus veers off the road towards a cliff. She realizes this before they reach the edge of the cliff, but is unable to prevent the bus from toppling over. As they are falling, Courtney and Duncan embrace each other in fear; the entire cast survives due to Leshawna's stretching bra and a lucky break, though. As most of the cast is shown sleeping while they await rescue, Courtney is seen snuggling with Duncan. They both qualify for Total Drama World Tour. Courtney is shown in the confessional near the end of the episode; she expresses distrust for Gwen, worried that she'll be a "boyfriend stealer" and try to steal Duncan away from her. Courtney states that she'll keep an eye on her in the third season.
In the Total Drama World Tour opening sequence, Duncan and Courtney are seen together on a boat. Duncan throws an oar at Harold (who was posing on the roof of the boat) and knocks him out. Duncan laughs hysterically at Harold's misfortune, while Courtney smiles at Duncan. They then crash into an inflatable raft carrying Gwen. Duncan grins at Gwen until he notices that her raft is sinking. He then looks down with a look of worry at Gwen, then turns around and sheepishly grins at a glaring Courtney.
As Chris introduces the third season's contestants at the beginning of the episode, Courtney is introduced first, followed immediately by Duncan. Duncan is seen carrying Courtney's backpack for her, and seems to have no objections to doing so. However, after Gwen smiles at Duncan because of a joke he made about Heather, Duncan grins back at Gwen, causing Courtney to glare at Duncan disapprovingly. During the Come Fly With Us musical number, Duncan is shown to be extremely reluctant to participate. Courtney begs him to do it though, since she doesn't want to see him be eliminated so early. Due to Courtney's sincere pleading, he gives in and sings the final line of the musical number.
Later, in the "Pyramid Over Under" challenge, Courtney pairs up with Duncan. She prepares a belay for her and Duncan, stating that rock climbing was the team-building challenge when she was a C.I.T., and that her "superior belay skills" will assure victory for the two of them. However, after Duncan sees Gwen having trouble scaling the pyramid by herself, Duncan tries to get Courtney to invite her into the team, which Courtney reluctantly agrees to, citing that a "three-person belay is stronger.” While climbing the pyramid, Courtney comments on Gwen's "appalling" form of rock climbing, which Gwen sarcastically thanks her for noticing. The two girls bicker the entire time while climbing, much to Duncan's annoyance. Once the trio gets to the top of the pyramid, Courtney and Gwen get into another argument over whether they should untie themselves or not. After Chris shouts at them that the three of them have to sing a reprieve of their earlier musical number due to not finishing in time, Duncan snaps and angrily goes down the pyramid, dragging Courtney and Gwen down with him. When Duncan quits, Courtney gasps in shock, clearly disappointed that he's not going to be by her side for the rest of the competition.
At the beginning of the episode, the girls of Team Amazon were discussing Duncan's disqualification in the previous episode. After Heather expresses her belief that Duncan "can't sing,” Courtney is quick to stand up for him, stating that Duncan "can do anything he sets his mind to.” She then shows compassion about his current well-being, worried that he's feeling miserable due to being stuck on the airplane waiting for a ride home. As she does so, she calls him "poor thing" in an endearing manner. Moments later, Sierra makes an offhanded remark to Izzy about how Duncan and Courtney are the most popular couple on the show, according to the readers of her Total Drama fansite.
Later in the episode, during the race to the Nile, Alejandro tries to get on the good side of the girls of Team Amazon, referring to them as "fiercely intelligent women" after they toss some insults towards his team. Courtney dismisses his attempts at flattery, quickly pointing out to him that she's with Duncan. Alejandro persists though, and replies that it's a pity that she's given herself to a "quitter who doesn't deserve her.” This catches Courtney off-guard, and she stammers as she tries to respond, implying that she perhaps believes at least some of what Alejandro is saying. Wanting to escape the situation, she yells to the camel she's on to go faster.
During Sea Shanty Mix, Courtney is pointed by Gwen towards seeing something that looks like Duncan on a rock sailing to the Newfoundland coast. When they head there, Courtney appears to be happy to have found him until discovering it's merely a rock that looks like Duncan. When Sierra implies that Courtney depicted a strangely-shaped rock as Duncan because when a person misses someone a lot they start seeing them even though they aren't there for real. Courtney agrees that she misses him a lot, but also states that this doesn't make any sense since Gwen "saw him" too. In the confessional she said she was mad at him for "abandoning" her. She then states that she messed up (something Courtney would never do) but catches this and tries to get the tape back.Changing Guard Mix, Courtney says she can't strip the guard down due to the possibility of Duncan freaking out. Then at the end of the episode, after Duncan returns to the competition, Courtney scolds Duncan for "abandoning" her, greatly annoying him. But then, she hugs him and tells him that she isn't really mad; she just missed him. Duncan's feelings appear to no longer be mutual, as he looks directly at Gwen (who was standing behind Courtney), saying "Every time I ran from the cops, I thought of you." Courtney naturally believed that Duncan said this to her, not seeing Duncan's attentions fixated elsewhere. Soon after, Duncan barges in on Gwen in the confessional and they start kissing; their actions setting the stage for a vicious love triangle scenario in the near future. Greek Mix, Courtney finds that Duncan indeed has a great singing voice and swoons over it, ironically being too far away to make out the lyrics, which pertain to the love triangle going on that she is unaware of still. After Duncan and Gwen's challenge is over, Courtney becomes deeply concerned about Duncan, constantly asking where he is and if he is okay, because she has not seen him since the beginning of his and Gwen's challenge. When Alejandro forces Tyler (the sole witness to Duncan and Gwen's kiss) to reveal to everyone what he's seen, Courtney is devastated, but at this point more enraged than anything else. She screams at Gwen for her betrayal, admitting that they were actually becoming "friend-ish." Back on the plane in first class, Courtney is seen being comforted by Heather as she breaks down and cries over her loss.
At the beginning of the episode, Courtney is shown making a list which includes getting back at Duncan and Gwen. In the confessional, she reveals that she still feels betrayed by Gwen, and that she apparently broke up with Duncan on "her terms," saying that it felt empowering. It is then revealed that she broke up with him by dumping a bowl of spaghetti on his head. She then breaks down crying in front of him and the other contestants, kicking and sobbing on the floor, while Duncan looks at her with a face that looked as though he felt guilty. She then calls him and a "stupid jerk-face" and other words that weren't heard because of her crying. Duncan tries to apologize to her, but she interrupts him by kicking him hard in the groin. Courtney's confessional is then continued, in which she says in a cracked voice that she at least still had her pride, before finally breaking down and beginning to cry. Later, Courtney gets angry when Duncan openly flirts with Gwen, so Alejandro confronted her, saying she should flirt with someone else to make Duncan jealous. She decided to flirt with Tyler, which Duncan didn't seem to like too much. When Courtney later "flirted" with Tyler again, Duncan seemed surprised and possibly a bit upset, later revealing that he knew Courtney hated him, but he didn't think that she hated him that much. When she sees Duncan getting zapped by aliens just before crossing over into Area 51, Courtney laughs hysterically at his misfortune. Later, when Tyler was eliminated instead of Duncan, Courtney gets angry and whacks Tyler out of the plane. Courtney told Duncan that she'd get revenge on him and his new girlfriend, which he just smirked at.
Still obsessed with getting revenge on Gwen and Duncan, Courtney starts flirting with Alejandro, not knowing Duncan and Alejandro agreed to prank Courtney, letting her believe Duncan is getting jealous. As Duncan pretends to be hurt, not only Courtney believes it, also Gwen does. During the second part of the challenge, Alejandro and Duncan take the strategy to the next level, while Alejandro is surprised after learning Courtney indeed wants to lose the challenge. After Team Chris Is Really Really Really Really Hot wins, Courtney celebrates the results, while Duncan is late to realize their win meant the possibility of Gwen's elimination, as Courtney has planned. After the voting and the tie-breaker, Courtney manages to get rid of Gwen, and now she plans on getting back at Duncan too.
Courtney demands an apology from Duncan. He acts like he doesn't know what to apologize for, and refuses to apologize for kissing Gwen, which just makes Courtney angrier. Courtney tries to flirt with Alejandro to make Duncan jealous, but he apparently didn't care much.bear instead. After the bear attacked her, Duncan and Courtney were paired for the wedding challenge even though both did not want each other (Duncan actually tried going back into the machine). Courtney was even considering trying working with the bear. They fought constantly, stating each other's flaws. Although they were paired together, Duncan purposely gave Courtney wrong directions to taunt her. At the tight rope challenge, Duncan carried Courtney and they both passed customs. They both argued with each other, Courtney saying that Duncan was an insensitive jerk and mocking about his piercings while Duncan says she could use some mouthwash. When Chris says that they've won the challenge and that they have to share first class, they both angrily glare at him. Immediately after this, Courtney demands a divorce while Duncan sarcastically replies that he wanted to "stay married to your sunshiney-self forever."
They are seen together in first class, but do not seem to enjoy each others' presence. Duncan admits he likes the silent treatment, but feels he needs to have Courtney in an alliance in order to overthrow Alejandro. He tries to talk to her and even calls her "ex-wifey" and "Court." Still holding a grudge against him, Courtney throws him into the cake. During the race challenge, Duncan stops and laughs at Courtney when her bike got stuck in a crack. When Alejandro asks Duncan about winning Courtney's loyalty, he replies that she hasn't got any of that, saying that he had already tried, relating to when Duncan tried to get Courtney to team up with him against Alejandro, but completely backfired. They continue arguing when Duncan mocks Alejandro for helping Courtney, saying that "Miss C.I.T." was now "Miss I Can't Do It Myself." Later in the race challenge, Courtney angrily says to Duncan that he was a loser because of his insults towards her. When Chris was on his phone, Duncan asked him if it was Courtney wanting him to say to her that she was a loser. Duncan also noticed that she was eating something during the food challenge. After it was revealed she was helping Alejandro cheat, Courtney was eliminated along with Blaineley in a double elimination. She tells Duncan that she is planning a defamation lawsuit against him. Duncan, however, doesn't seem to mind, as he sarcastically says goodbye to her instead, noticeably with a satisfied smile on his face. In a deleted clip, Courtney calls Duncan the Lover of the Goths and is happy now that she is away from him.
Alejandro comments that Duncan is as happy as ever, and he nods, saying that "it's as if all of his problems were pushed off a plane," obviously referring to Courtney. Duncan also noted that his romance with her is a failure.
Courtney displays dislike towards Duncan when he stood next to her, calling him "Jerk-face." Throughout the episode, Courtney wanted to sing a song she wrote that is basically a hate-song expressing her dislike for Duncan and Gwen. She tried to sing it on several occasions, but was interrupted by something else. Her first attempt was during Who You Gonna Root For?, and she sang that Gwen was a boyfriend stealer and that Duncan was a dead man, but Geoff stopped her. She started to sing her song again, with the first line mentioning that Duncan never used soap, just before the song I'm Winning This began. Also, in a deleted scene from the episode, Courtney tries to sing the song for a third time, while she is standing next to Gwen and Duncan (who are relaxing on the beach in lounge chairs, alongside other couples). When Courtney starts singing again, Duncan finally gets so fed up that he throws a sandal at her face, knocking her down.
Courtney is seen fighting Duncan and Gwen with a burning jousting stick while she glares at them menacingly.
Duncan is annoyed by Gwen sighing over being labelled a villain, saying he "might as well be dating Courtney". Later, Courtney glares a few times at Gwen, still clearly upset over the events of Total Drama World Tour. When Gwen complains to Duncan about Courtney's glaring, Duncan offers to glare back at Courtney on behalf of Gwen, which he does. However, Courtney ignores him. Duncan tries to get Courtney's attention, but she continues to ignore him. In a confessional, Duncan seems to feel hurt that Courtney is completely ignoring him now, but he shrugs this off.
Following Duncan's confessional, Lindsay tells Courtney that Duncan may want to be yelled at for old times' sake. However, Courtney states that it'd be pointless, since Duncan "never listens". Furthermore, Courtney seems to have accepted that things are finally over between her and Duncan, stating that things probably wouldn't have lasted anyway due to him being a "bad boy".
Duncan believes that Courtney is pretending to be interested to Scott in order to make him jealous which he pretended to not be bothered. Throughout the episode, Duncan constantly asked Gwen whether or not Courtney is talking about him. This, along with several events in the previous episodes, is the breaking point for Gwen and she ends her relationship with him.
Gwen and Courtney routinely mock Duncan through the boxing challenge, both taking amusement in seeing him unable to fight the bird he had been unable to bring harm to in the previous episode as the two of them rebuild their friendship. However, when Chris pits the two girls against each other in a fight they both refuse, prompting Chris to pull out a montage of clips from Sierra's blog of all the time Gwen and Duncan kissed in World Tour. This clipshow infuriates Courtney once more, and she hammers Gwen with blows as she vents her anger over her kissing her former boyfriend. Duncan sees this and is pleased to see the girls fighting over him, bragging to Alejandro as he watches. However, when the girls exhaust themselves in their fight, Gwen admits she only wanted to make things better with Courtney, and Courtney responds that she had gotten over Duncan and never truly missed him after season three but had actually missed Gwen, much to Duncan's shock and dismay.
Duncan wanted to be in an alliance with Courtney and Gwen. Duncan says he could protect them from Mike but since Mike is one of the nicest people in the competition they laugh at Duncan and refuse his alliance offer.
