Heather was Total Drama's first villain. Famously manipulative, Heather knows what she wants and exactly how to get it. Her strategic smarts have proven effective, eliminating a record amount of contestants. She competes with her sights solely on the prize money and not on making friends, using others at her advantage and only being kind when she may ultimately be benefited. This makes it difficult to differentiate her classic mean girl ways from genuine heartfelt moments.
Such an example is in Total Drama, Drama, Drama, Drama Island, when a tearful Heather tells Harold that she doesn't like "being mean all the time" and it's not fun "being the one everyone hates". Hawaiian Punch, in which she becomes ecstatic at the thought of being the "good guy", confirms that there is at least some truth to her lament. However, even romance is not enough to tame Heather's desire for victory as shown with her relationship with Alejandro.
Much to her dismay, Heather learns that she will be spending her summer in a rundown camp and attempts to leave the competition only to find out she couldn't due to the fine print of her contract. Heather is placed on the Screaming Gophers and immediately gets in a conflict with most of her team mates, mainly Leshawna and Gwen. Heather refuses to jump off the cliff in Not So Happy Campers - Part 2, not wanting to ruin her hair. This leads to an argument between her and Leshawna which culminates in the latter throwing her off the cliff. Heather vows to get revenge on Leshawna, but during the final moments of the challenge, she insincerely apologies to her. When Lindsay questions her motives, Heather simply reveals that her intentions were to keep Leshawna's guard down, emphasizing the importance "keeping your friends close, and your enemies closer".
In order to secure her victory, Heather convinces Lindsay and Beth to form an alliance with her in The Big Sleep, under the promise that she will bring them to the final three with her. In reality, she is simply using their naivety in order to further her own goals. During the challenge, Eva accidentally drops her MP3 player, which Heather steals, knowing that Eva would throw a tantrum and turn her teammates against her. The plan works, with Eva trashing the Bass's cabins and get eliminated. With Beth and Lindsay's help, Heather easily takes up leadership over the Gophers, despite being disliked by many. In addition, the two are required to follow all her orders, including doing her chores. Heather, however, has a problem controlling Lindsay's growing attraction to Tyler, and repeatedly scolds her whenever she sees them together. When Lindsay leaves with Tyler for a date during Dodgebrawl, Heather angrily throws a kayak onto Tyler to keep them apart.
Heather's most noted enemy on the island other than Leshawna would be the Goth loner, Gwen. The two had long, complicated rivalry that intensified throughout the series. Gwen is the primary victim of Heather's tormenting, and though the conflict is usually verbal, with Heather calling Gwen "weird Goth girl", they sometimes get physical. Though the two didn't have a good start on their first day, their rivalry begins in Not Quite Famous. After telling Lindsay to distract Gwen, Heather sneaks into the cabin and steals Gwen's diary. During the talent show, Heather would read out the contents of Gwen's diary to the entire world, including of her secret crush on Trent. Her actions disgusts everyone, including Chris and Courtney. After her team loss, Heather knows that she would be the primary target for elimination but is spared by convincing her alliance and bribing Owen with a cake, to vote off Justin instead. Gwen would then get back at Heather by dumping Harold's red ant farm in her bed during the night. In the next episode, Heather vows to eliminate Gwen the next time they lose until she is calm down by Trent.
As Heather continues to run her alliance like a dictator, Beth slowly comes to realize Heather's true intents and begins to rebel against her. After risking her life to steal a bag of chips for Heather in Paintball Deer Hunter, Beth finally loses her patience. She deliberately disobeys Heather's instructions and eats the chips herself. Later, Beth confronts Heather and quits the alliance, causing a massive paintball fight between them and Leshawna. Watching their fight from afar, the Killer Bass use this opportunity to shoot them, leading to the second consecutive loss for the Gophers. Heather chooses to eliminate Beth for her betrayal but she is spared. Still angry over her betrayal, Heather continues to torment Beth in If You Can't Take The Heat... As before, Heather appoints herself as team leader but her constant bossing eventually make Leshawna snap and lock her in the freezer. When her team loses again, Heather discovers about Beth's Tiki idol that she took during their previous trip to Boney Island and realizes that she is responsible for their losing streak. Because of this, Beth is eliminated much to Heather's satisfaction. With Beth leaving the alliance, Lindsay is the only ally of Heather left in the competition.
For the next few episodes, Heather's suffers from misfortune during the challenges. In Who Can You Trust?, she fails the second part of the challenge she participates in due to Lindsay, which lands her in the infirmary. In Basic Straining, she is the among the last three members of her team left during the challenge but quits in order to escape from Owen's gas, only for Owen to fall on her moments after she landed. In X-Treme Torture, Heather volunteers to drive the jet ski for the Bass. Heather tries many attempts to shake Harold off, but the latter manage to grab all the flags despite losing his skis. As they slowly approach the finish line, Heather try one final attempt to make sure the Bass didn't win. She attempts to cut the rope Harold is holding onto, but a tree branch snags her top and leaves her completely topless. Despite the humiliation, Harold still fails to reach the finish line after being entranced by Heather's breasts.
When the teams are divided into boys and girls in Brunch of Disgustingness, Heather attempts to pull Bridgette, the sole female Killer Bass remaining, to join her alliance but her attempts are thwarted by Leshawna. Heather tries to act friendly towards Bridgette throughout the episode, including sharing her make-up but ultimately, Bridgette decides to side with Gwen and Leshawna. Soon, the teams are merged and Heather faced a returning foe, Eva. Fortunately for Heather, Eva has not discovered of her actions that lead to Eva's earlier elimination. Heather initially decides to vote for Leshawna but since she has immunity, she decides to vote off Eva again due to her temper.
In Search and Do Not Destroy, Heather has trouble getting her key as it is located inside Chef's freezer, guarded by Chef Hatchet himself. Nevertheless, Heather manage to retrieve her key with Lindsay's help. Later, Heather spots Gwen and Trent sharing a kiss and consider this a start of an alliance. In order to break them up, she enlists Lindsay's help to organize a situation where Gwen would find Heather kissing Trent on the Dock of Shame after telling numerous lies to Trent about Gwen. This incident breaks Gwen's heart and Leshawna would rally the others to vote off either Heather or Trent. Since Heather had invincibility, Trent is eliminated instead.
Lindsay continues to help Heather in many of the post-merge challenges and still believes that Heather is her friend. Heather however continue to use Lindsay to ensure her own safety. In Hide and Be Sneaky, although Lindsay is the one who discovers DJ and Owen's hiding place, Heather claims invincibility for herself and refuse to share with her. In That's Off the Chain!, Heather is able to trick Lindsay into building a fast bicycle for her and during the race, she instructs her to clear a path through the obstacle courses, allowing Heather to reach the finish line first with Lindsay coming in second. However, since they are the only contestants to cross the finish line, Lindsay is technically the last one to cross and is eliminated. Heather finally reveals she does not care for Lindsay, never intending to keep her promise and was using her the entire time. This revelation causes Lindsay to snap, giving Heather a hate speech including a string of expletives, along with a middle finger gesture.
With Lindsay's elimination, Heather has lost all her allies and struggles in all subsequent challenges. By ignoring Gwen's advice in Hook, Line, and Screamer, she is easily captured by Chef while she is about to take a shower. In Wawanakwa Gone Wild!, she had the hardest animal to capture, a bear, as oppose to the others who had to capture small animals. Duncan offers to help her but she initially refuses. By the end of the challenge, not only she fails to complete her challenge, she is shot by Izzy with a tranquilizer dart, putting her in a state of paralysis for the remainder of the episode. She is partnered with Owen in Trial by Tri-Armed Triathlon, who is probably the only person left on the island who still treats her nicely but after insulting Izzy in front of him, Owen snaps at her. Despite these disadvantages, Heather manage to survive to the final four due to others being eliminated as a result of poor performance in challenges, being too popular and accidentally been voted off by the eliminated campers and a parrot.
Heather and Gwen continue to be on each others throat in Camp Castaways, with Duncan getting caught in between. The three of them struggle to survive on a deserted island together until Owen returns and convince them to get along. In Are We There Yeti?, Heather reluctantly teams up with Gwen in order to defeat Owen and Duncan. Using deceptive tactics, such as pretending to be weak, helpless girls, Heather and Gwen win invincibility and Duncan is voted off. Unfortunately for Heather, her luck runs out in I Triple Dog Dare You! as Gwen and Owen teams up in order to eliminate her by forcing her to compete in every challenges they throw at her. Heather endures them all, until she is faced with a challenge given by Lindsay. At first, Heather believes that Lindsay would not be smart enough to come up with a tough challenge, only for her to realize that she is required to get her head shaved off by Chef. Heather is torn between what to decide on as Chef inches closer with the razor blade, and kicks it out of Chef's hands before making a decision. The razor blade ends up landing on top of Heather and shaves most of her hair off anyway, leaving Heather's head a disfigured mess. Since she does not actually accept the dare, Heather is then eliminated. Frustrated over her defeat, Heather leaves the island and threatens to sue the show.
Now wearing a wig to cover her bald head, Heather chose to support Owen in the finale. Heather would go through great lengths to ensure Gwen doesn't win though most of her attempts would ended up backfired including the laxative-laced muffin that she gave to Gwen before the challenge which Owen ate. Heather's pride is lost when Leshawna takes matters into her own hands and locks Heather in the confessional after Owen uses it and she remains there even after one of the finalist has reached the finish line. As the boys prepare to throw Chef into the lake after doing the same to Chris earlier, Heather and Gwen had a friendly banter with each other which ended with Gwen teasing Heather of her foul stench.
In Total Drama, Drama, Drama, Drama Island, Heather's past actions throughout the season has made everyone refuse to ally with her and she resorts to forming a team with Harold. After retrieving the briefcase, Heather betrays Harold and uses the hang-glider he built to fly to the Dock of Shame but it falls apart and sends Heather head-first into a beaver dam. In the process, the case falls out of her hands and into the water. Later, a beaten-up Heather, having finally escaped the angry beavers, encounters Harold yet again, as he pulls up alongside her by the river in a canoe. She at first doesn't want to be with him, as she is angry at her misfortune throughout the episode. But Harold is determined to help her, thus having a heart-to-heart talk with her to which Harold seems to understand. Harold forgives Heather and allows her to join him again, even offering to be her friend once they are done. However, Heather stares at the camera with a mean demeanor look on her face, showing that she is lying again. In the end, the two ended up in the lake with several other contestants and are qualified for the next season.
Heather is forced to suffer the consequences of her antagonistic behavior in the previous season. She is still hated by the majority of the cast, with virtually nobody trusting her, with the only exception being Harold. And to add to her suffering, she spends the entire season bald, losing her beauty and vanity from last season. Jokes are made at her expense, she is endlessly hated by her peers, and Heather learns a thing or two about humility. Heather, along with the rest of the cast, debuts to Total Drama Action in Monster Cash, with the same wig she has in The Very Last Episode, Really!. As soon as she steps off the bus, she immediately is at odds with Gwen, who she had a strong rivalry with her last season. Everyone shows that they have not forgiven Heather for her actions last season, as she is forced to work alone during the challenge. When the monster catches her and throws her in the bounce house, her wig comes off. This becomes a running gag. Later, no one wants to share a bunk with her at the end of the episode. When the girls draw Lindsay's makeup brushes, they decide that the one who draws the shortest brush has to share a bunk with Heather. However, they have their math off, and Heather ends up getting a bunk all to herself.
In Alien Resurr-eggtion, Heather still has no allies, especially due to the lack of teams. Once again, Heather has to participate in the challenge alone, since no one else wants to be with her. Lindsay and Beth also discuss Heather in the confessional, and how much they distrust her due to her manipulation of her last season. She ends up grouping up with Owen, Izzy and Harold. She is separated from them when they encounter Chef Hatchet, and Izzy tells them to make a run for it, as Izzy herself confronts Chef. Afterward, Heather is looking around when Chef ambushes and chases her, claiming that he is getting revenge on her for putting laxatives in his food in last season's finale. Heather is shot and her wig falls off and through the grates in the floor, becoming upset that her precious wig is lost forever. In the confessional, Heather talks about how, back home, she has tried many methods to grow her hair back. She talks about how she tried "traditional Burmese medicine", but spits it out, yelling "Loser Shaman!" At that night's Awards Ceremony, Heather receives her first Gilded Chris Award.
When the time comes to choose the teams in Riot On Set, and Gwen and Trent are in charge of picking the teams, Heather believes that she will be picked very soon. To her shock, she is not. She begins to lose hope that she won't be the last one picked. Gwen, not sure who to pick, is reminded by Leshawna to "keep her enemies close", and tells Gwen to choose Heather instead of Izzy, which she does, much to Heather's surprise. She is placed on the Screaming Gaffers. When the challenge begins, Heather believes that they should hand each other the supplies in relay fashion. Her team disagrees, and get her to be quiet. Harold comforts Heather, telling her to write down all her ideas and discuss them in the next team meeting, but Heather treats him rather harshly, calling him "trout lips" and telling him to jump in a lake. When her team fails to get their trailer to the top of the hill, Heather wonders how they are going to do makeup without proper vanity lightning. She ends up getting stuck on the cable of a light, and Harold helps her down. Heather considers forming an alliance with Harold.
In Beach Blanket Bogus, Heather continues to be shunned by her fellow castmates, bar Harold, who is the only one who attempts to reach out to her. Despite this, Heather coldly rejects Harold. She takes her breakfast, and smiles at Lindsay and Beth. However, they give her the cold shoulder, which forces her to find a new place to sit. Later, as Duncan bullies Trent, Trent throws some salt back to get rid of any bad luck. This salt ends up getting in Heather's eyes, becoming temporarily blinded. She then sneezes uncontrollably when she gets pepper up her nose, running away screaming. While she is not seen participating in the surfing challenge, Heather is seen working hard in the sand castle building challenge, and even admiring Harold's work, the "Taj MaHarold". After her team loses and Chris forces the castmates to find firewood, Heather is the only one to question why they had to do so in the first place when Chris already had fire, only for Chris to show Heather his manicured hands.
In 3:10 to Crazytown, Heather is bogged down by the intense heat, just like everyone else, and shares an umbrella with Leshawna for shade. Heather and Leshawna end up having to break the tie for their team. Both climb the ladder to jump onto the horse while insulting each other. One of the insulting topics thrown between each other is Heather mocking Leshawna for her weave, which poofs up due to the humidity. They also insult each other's fashion choices while climbing up the ladder. In anger, Leshawna pushes Heather off and is pulled down too because Heather grabs hold of her arm, but they both land on a roof ornament and hang by their pants. Leshawna's pants rip on the weather vane and she falls off, but she still misses the horse, while Heather is left hanging off the plank. Both teams are then tied with three points each. During the second challenge, Beth manages to successfully rope Heather when the Killer Grips play as the cowboys, and the Screaming Gaffers play the cows. After the challenge, when the castmates bathe in the barrels, Heather glares at Owen when he implies that he wants to use the bathroom inside the barrel before she bathes in it.
Heather is brought up a few times in The Aftermath: I, during Geoff and Bridgette's argument. As they discuss the Gwen and Trent drama, Bridgette states that Gwen stabbed Trent in the back and had him voted off to cover her own butt, and Geoff brings up Trent kissing Heather in Search and Do Not Destroy. Bridgette says that Heather tricked Trent into doing so, and Geoff calls Heather the "hottest girl" on the show, and claims that Trent would not have to be tricked into kissing her for that reason. Sadie brings it up again, when she states her reason for switching to "Team Gwen". In The Chefshank Redemption, Heather, among the rest of the girls, is surprised to find out that they are locked in their trailer. After Heather complains that the trailer is "as small as the space in between Lindsay's ears," she then gets talked into slipping through the roof by Gwen, who uses one of Heather's weaknesses: Shameless flattery, saying only someone as thin as a toothpick could fit through. She says that "surely the most athletic of us would want to show off her natural sleekness!"
Once the first challenge ends, Lindsay reminds Gwen that she should have allowed the Grips to win. Heather, seeing Gwen talk to Lindsay, immediately confronts Gwen, and suspiciously asks what she was talking about to Lindsay. Gwen shoves aside Heather's suspicions and walks away, leaving Heather still very much suspicious. Gwen arouses more suspicions from Heather as she insists on pushing the cart for her team, followed by a wink to the Grips, signaling to them that she will be helping them win the challenge. Once the Grips pass up the Gaffers several seconds later, Heather's suspicions rise high enough for her to begin suspiciously questioning Gwen about why she had stopped and why the Grips kept mentioning Trent's name. In an effort to convince her team that she had stopped for a legitimate reason, Gwen attempts to fake a cramp. Heather, still suspicious, then tells Gwen to keep moving, despite her "cramp", and Gwen complies. Duncan and Leshawna give Heather flack for this, with Duncan stating that "if she's got a cramp, then she's got a cramp. We humans get them." Heather insists that she has "just the thing for cramps", and makes Gwen keep moving. When Gwen asks Leshawna to slow down her digging in the later challenge, Heather suspiciously asks Gwen why she is not being supportive of her team and questions whether she wishes to win the challenge at all. Gwen denies Heather's assumptions, saying she is only concerned for the well-being of her teammates.
Before the end of the challenge, Heather begins to get excited about winning again. When Izzy arrives, she tells the Gaffers to follow her to the finish line, as she knows a "shortcut", which makes Gwen nervous. Heather, noticing Gwen's nervousness, provokingly tells Gwen how great it is that they had found a short-cut, knowing that she didn't want them to win. At the Gaffers' table, Heather taunts Gwen, saying that she will be voted off, to which Gwen asks her how she is so sure. Heather replies, saying that she had seen through Gwen's "stunt", assuring her that she knew that she threw the challenge. DJ then brings Gwen a dish of food, in order to "keep her strength up". Gwen then thanks DJ, and Heather looks on angrily. Later, the Screaming Gaffers are shown at the Gilded Chris Ceremony. At the ceremony, Duncan, Leshawna, DJ and Harold all receive awards, while Heather and Gwen continuously glare at each other. Chris then announces that Heather receives the last Gilded Chris. Heather then, excitedly, takes Chris's place at the podium by pushing him down, telling Gwen that she is not a winner and is, therefore, a loser, to which Gwen only glares. Heather is shown declaring that with the three votes for Gwen she knew of (her own vote, plus Harold's and Leshawna's), Gwen would easily be eliminated.
In One Flu Over the Cuckoos, Heather is the only castmate on her team who is not surprised about Gwen being a traitor, having known the truth all along. Heather can't believe Izzy returned, which ruined the Gaffers' number advantage, stating it is the only advantage they had. When Chris arrives and explains the challenge to everyone, Heather then protests that it is already very late, to which Chris just begins to talk about how "no medical school all-nighter is complete without pizza". When Duncan says that the pizza tastes good, Heather wonders how that is possible. As the Screaming Gaffers study in the crafts services tent, Heather becomes suspicious and wonders where DJ is after Harold tells Duncan to save some pizza for him. However, DJ manages to save himself by showing up just in time. Duncan and Leshawna decide to go to sleep, believing they do not have to win since it is a reward challenge. In the confessional, Heather is then shown talking about how she could have forced them to stay, but claimed that they couldn't help the team win unless the challenge was about piercings or plus-sized shopping.
Leshawna discusses the prospect of an alliance with Heather, to get Heather off her back. She also believes they should watch their backs around her. When Chris asks the castmates if they are prepared for the challenge the next day, Heather claims that some are more ready than others, indicating Leshawna. Leshawna responds by saying that she made had own choice, while Chris grows excited over the tension between them, calling it his "favorite". When Chris reveals that only one castmate can enjoy the reward of the challenge, Duncan asks who "the one" will be. Heather says it will be "the person who most directly contributes to the win". In the confessional, Heather is shown talking about how she will be the one who will receive the reward. Heather performs well in the Visiting Hours challenge, working especially well with DJ. When Justin identifies symptoms of a disease in the textbooks, Beth says is "Mortatistical Crumples Disease" which she recalls is fatal.
Adding to the fear and shock already in place from this news, Heather adds that is it also highly contagious. After the castmates find a sore on Owen, Heather then spots another sore on DJ. As Owen scrambles around the hospital set in his bubble, Heather calls him a "deranged pinball of death". Heather becomes victim to Mortatistical Crumples Disease, and suffers seasickness. Heather, writing her will, leaves all her awards and recognitions to her mother, having to vomit frequently. She continues her will, leaving nothing for her siblings, telling them to earn it themselves, referring to them as "lazy slackers". After Leshawna and Duncan win the challenge, she brings up the prospect of an alliance to Duncan and Harold again, saying she only wants to get Heather out of her face. When Chris shows the reward, Heather's mother is seen. When Leshawna starts crying crocodile tears in order to win the reward, Heather comments on how Leshawna truly does have a heart, sympathizes with her, and agrees with the rest of the team to let Leshawna have the reward.
In The Sand Witch Project, Heather stops trying to befriend Lindsay and Beth, and insults them. She calls them "spineless followers", which causes Lindsay to take leadership of her team. Heather is part of the second part of the horror movie challenge. In her challenge, she is forced to kiss Duncan. Both are extremely disgusted by this. They pull apart quick after their kiss, and Heather says that Duncan "tastes like street", and says that her lips may never recover. When the "killer" finally arrives, Heather is too disgusted by the kiss to scream properly. After Chef Hatchet's interference in the challenge, DJ faints, and Heather slaps him to wake him up. After DJ says he needs to see Chef, Heather slaps him again, stating that he is still "talking crazy". In the second part of the challenge, according to the plan, Heather has to dress up as a police officer. Harold suspends Heather over the Grips, who manages to scare all of them, except for Lindsay (who is later scared by DJ's interference). Once the Killer Grips are gone, DJ walks toward the hanging Heather and sees the "conscience momma" telling him that he did a bad thing and she would never forgive him. At the end of the episode, she is shocked when she finds out that DJ was in an alliance with Chef all along.
In Masters of Disasters, Heather is surprised to find out that Beth has a boyfriend, and points out that Beth never mentioned she had any boyfriend before. When Harold talks about his surgical kidney swap and says he is a "rare case", Heather agrees, but in an insulting fashion. When she sees Owen devour the food, Heather states her theory that Owen's taste buds packed up and moved to France years ago. Heather performs well in the first challenge, being one of the only three castmates (the others being Duncan and Leshawna) to complete it. During the second challenge, as the water rises in the submarine, Heather, annoyed, mocks Leshawna's poofy hair, again, making a "big girl" joke about her, and the two get into a slap fight. Duncan manages to pull them apart. Heather becomes scared. She holds onto Duncan, which Duncan seems to enjoy. Heather is disgusted by this, and splashes water on him. When she finds out that Leshawna was crying crocodile tears to win the reward in One Flu Over the Cuckoos, she becomes furious, and exclaims "You're gonna pay for this, big, loud and proud!" After the castmates escape and Chris tells the Gaffers their reward for winning, Heather talks about her disdain of it on the confessional. In Full Metal Drama, Heather tries very hard to make sure that the Killer Grips don't hear Leshawna's farts during the challenge, singing "Hush little baby, don't you cry, if you do, we'll surely die."
In Ocean's Eight - Or Nine, Heather watches Duncan carve pictures into the table of the crafts service tent with his knife, and calls him a vandal. Then, she turns to Harold and, frustrated, calls him a nerd. Harold replies by blowing a raspberry at her. After Leshawna tries to get everyone to get along, Heather gives her the cold shoulder with the rest of her team. Before the challenge could be started, Justin tells Chris that their team is missing a player right before Heather says the same, in an disinterested tone, that they are missing one, but they don't care. At the Gaffers' vault, Harold tries to unlock the vault, but Heather starts an argument with him by telling him that she needs to do it. Harold uses facts as to why he needs to be the one to unlock the vault, as he gained experience from being a captain of Picky Steve's Lock Picking Camp. However, Heather slaps his hands so she can try. He then slaps her hand away, and they both get into a slap fight over who's the better lock-picker, forgetting all about the actual experienced criminal, much to his annoyance and somewhat also insult. Harold, seen brutally beaten, still seems to be trying to unlock their team's vault. Heather begins getting impatient and starts to tap her foot, as Harold says he needs silence.
Heather begins to think strategically as to what the code might be, as she thinks Chris was the one who made the combination. She believes that the combination could be about something that he loves; himself. First, she tries his birthday. Getting it incorrect, Harold makes a buzzer noise, as if they were on a game show. Heather then tries Chris' measurements, incorrectly, and gets another buzzer noise from Harold. Before she could even get her third suggestion in, the bar code number on Chris' favorite hair gel, Harold makes the buzzer noise, much to her anger, as she tells Harold angrily to stop making the noises. Heather comes up with another idea, using a bobby pin, which doesn't work. Eventually, Duncan and Heather decide to leave Leshawna. Duncan, Harold, and Heather then arrive at the bank robbing site and actually beat the Grips, on account of Owen's hunger slowing them down. At the car site, Duncan, Harold, and Heather are seen working on the now-seen-to-be go-karts. When the Screaming Gaffers win the reward, they head back to the trailers, and Duncan dumps out the money, thinking that it's really money. Heather reads out that it is "non-negotiable Chris cash, accepted only in the Total Drama Action craft services tent towards the purchase of tap water".
Heather's inner conflict concerning her hair makes a return in One Million Bucks, B.C.. She becomes upset that Lindsay has hair, and she does not, when it is Lindsay's fault that she is bald in the first place. Meanwhile, she and Leshawna start fighting due to Heather leaving Leshawna in the vault in the previous episode, which she does not regret. When Lindsay gets a knot tied in her hair, Heather volunteers to brush it out, and does so very roughly, hurting Lindsay. At this point, Heather has become desperate for hair, but believes she is too smart to be "Lindsay blonde", and does not want "Leshawna's gross weave", or "Beth's pathetic ponytail". When Courtney enters, Heather sees Courtney's hair, and she becomes very interested in it. She holds and admires some of Courtney's hair while telling Courtney that it's great to have her "hair", but corrects herself with "here". Before the challenge, Heather asks Chris if he has any wigs. Chris then tells the castmates to dress up in loincloths, and gives Heather a Flintstones-like wig. When the contestants line up, Courtney finds a claw in her loincloth. Heather, in an attempt to clip off some of her hair, is caught by Courtney and snips off the claw to cover it up. While Courtney is in the confessional, Heather manages to snip off some of her hair when she is not looking. In her own confessional, Heather laughs happily that she finally got a lock of Courtney's hair. She turns to the camera and says "I'm not crazy. I'm just bald."
In the second round of the challenge, Heather fights against Beth. While Heather throws random strikes, a giant Monster Loon snatches her new wig, and makes her fall forward, only to clings onto Beth's bone. Beth lets go of the bone, and Heather falls into the tar pit. When the Giant Loon comes back for its egg, Heather beats it up, and gets her wig back. Chris gets the last word in confessions, apologizing for the lack of plot development regarding Heather stealing Courtney's hair, explaining that due to Courtney's litigious nature; they literally "can't harm a hair on her head". In the exclusive clip of the episode, Heather, covered in tar, complains about how she thinks reward challenges are "such a waste of time", and that she really needs a makeover. She then excitedly pulls out the lock of hair she stole from Courtney earlier and sticks it to her head. However, a cameraman comes into the confessional and wrestles the hair from Heather. After he leaves, Heather puts on her red wig. She then realizes that the wig will not come off, and is excited because she finally has "hair".
In Million Dollar Babies, Heather refuses to participate in the first part of the challenge, but Leshawna forces her into helping. The next challenge pits Beth against Heather in a game of badminton. Heather begins pummeling Beth, and it looks as though all hope is lost for the Grips. The Gaffers start trash-talking Beth, and Leshawna tells her that her "chances of winning are about as real as your boyfriend". Her comment sparks fury in Beth, and she transfers her anger into the game, easily defeating Heather for the second time in a row. When Courtney reveals all the bad things that Leshawna said about everyone during her trip the spa, everyone becomes angry at her. Everyone except Heather, who says that she does the same thing, and wonders why everyone is so angry, despite Leshawna saying Heather is "mean, just for the sake of being mean." During Justin's slam dunk, he steals Heather's wig and dunks it. Leshawna returns the wig to its rightful place, on Heather's head. Before the cheerleading tiebreaker, Heather suggests that they make a cheer about her. In the actual cheer, Leshawna calls Heather "queen of mean", but says she has a "nice scalp for a groovin' teen."
However, despite her and her team's efforts, the Screaming Gaffers lose. In the Awards Ceremony, Chris reviews everyone's reason for possibly going home, and Heather's is that she lost the badminton game to Beth. To Heather's major shock, she is voted off instead of Leshawna, as Duncan and Harold liked and accepted Leshawna's apology. At the end of the episode, Leshawna goes with Heather on the Walk of Shame, to the Lame-o-sine, telling her she can consider themselves friends. Heather then gives Leshawna her wig from the past episode as a farewell gift, so that Leshawna can use it when her real hair looks "as bad as it does today". In her exclusive clip, Heather surprisingly isn't mad at her elimination like last time, stating that she can now have the time to to grow her hair back. She mentions that with her father being cheap, she might end up having a pony tail. Heather then comes up of a plan to cut her mother's hair while she is asleep and claim it as her own as her mother's hair has a nice volume. She ends the video saying the possibilities of how she will get a new set of hair are endless now that the show is over for her.
Heather makes an appearance in the Total Drama Aftermath in The Aftermath: III. She appears with a new wig this time, an afro wig.

When the Blue Harvest Moon appears, Heather becomes her polar opposite, a bubbly, kind, and happy-go-lucky person who hugs the animals and cares about everyone. Her sudden change in personality creeps her teammates. However, it turns out that she is only pretending to be under the effects of the moon in order to play with Alejandro's mind. Once the moon returns to normal, Heather stops her act and returns to her usual mean self.
Upon seeing that Gwen easily bonded with their new teammate, Cameron, Heather realizes that her and Alejandro are the odd ones out, and offers him to join a temporary alliance in No One Eggspects The Spanish Opposition, which he agrees to. This however, turns out to be it's actually just a ploy to gain his trust and to get him eliminated, since she still does not trust him. As the challenge proceeds, she convinces her team to vote him off, lying that he is trying to vote off either Scott or Cameron. At one point, Heather discovers the McLean-Brand Chris Head and hid it behind a rock until the challenge is over. After the challenge ends, Heather soon returns to get her idol, only to find out that it is gone and immediately accuse Chris for stealing it. Regardless, Heather believes with everyone's help, Alejandro's elimination is guaranteed. However, Alejandro not only reveals to her that his legs had recovered long ago, he is the one who took the Idol. Since Alejandro is immune, his sole vote against Heather is the only one that counts, devastating Heather. As Heather is placed into the Flush of Shame, Alejandro suggest that they should resume their relationship but Heather rejects him and push him off the giant toilet before she is flushed. The exclusive clip shows that Heather ended up in the Yukon and was attacked by a polar bear, after she ends up being stuck to a pole similar to Bridgette.
In the season finale, The Final Wreck-ening, Heather, along with Alejandro, is chosen by Mal to help him win the finale against Zoey. It turns out that after her and Alejandro's respective eliminations, they have finally become a couple and spend most of their time making out, much to the disgust of Chris. At one point, Mal attempts to throw Heather into the toxic waste but is stopped by Alejandro, who comes up with an alternate plan. She and Alejandro finally get across using a canoe. Near the end, Chris became frustrated with all the contestants kissing each other in some way and proclaims that anyone is capable of winning the million dollars if they pull out the sword first. Upon hearing this, Heather and Alejandro start fighting again, not wanting to lose a chance to get the prize money. After laughing at Alejandro being chased by Fang, Heather is hit in the head by Gwen. Eventually, either one of the original finalists still manages to pull the sword out first, frustrating Heather. However, pulling out the sword also leads to the destruction of the island. Heather is angry that she is cheated out of the million dollars again, and sarcastically calls the consolation prize of Alejandro "great". Her and Alejandro are last seen being chased by Fang.
