Sierra has a huge crush on Cody, to the point that it is considered to be an obsession. Throughout the third season, Sierra continuously annoys Cody while he is asleep, stealing his belongings and refusing to leave him alone. Sierra is also extremely jealous of any girl (Gwen in particular) getting close to Cody, and will not hesitate to attack anyone who hurts or is rude to him. Cody, on the other hand, rejects her due to him having a huge crush on Gwen since the first season, and finding her creepy due to her constant stalking of him. However, by the end of the season, Cody is much more warm towards her, even referring to them as best friends.
Cody never participates in Total Drama All-Stars while Sierra does. As a running gag, Sierra will often mention him several times or pretend that Cody is around. She also develops a crush on Cameron, believing that he is Cody.
In this episode, Sierra is introduced for the first time. While she has an interest in the Total Drama series in general, and has a website for all of the contestants, she appears to have a specific interest in Cody. Sierra was seen spying on Cody and The Drama Brothers party, as well as being fascinated with them and the rest of the Total Drama cast. She and Cody first interact on the red carpet when Alejandro pushes Cody down and Sierra shouts his name in a concerned way. At the end of the episode, when Sierra is in the confessional, she says she is excited to be in the next season because all her Cody blog questions will be answered. These questions included "How many freckles does he have on his back?," "What kind of deodorant does he use?," "How many times does Cody sleep facing west?," and "What song does he sing in the shower?" At the mention of the last question, she starts giggling uncontrollably, eventually saying that the last question "will definitely be a six-month analysis." The special foreshadows further interaction between the two in season three.
On the Cartoon Network site, it reveals that Cody's favorite place is "away from Sierra," and Sierra's favorite cast member is Cody.
In the opening sequence for this season, Cody falls off of the Statue of Liberty, and lands in Sierra's arms. Sierra smiles, and Cody looks blankly up at her. Sierra then hugs him awkwardly, shocking him, and making him unable to breathe. Later, when the contestants parachute off the human pyramid they made, Sierra is shown to be holding Cody bridal style as they land on the ground.
The very moment Sierra gets off the bus, she starts hyperventilating when she notices Cody. She rushes over to him and tells him that she had dreamed of meeting him for so long, except that he was shirtless, which he seems quite scared by. She later tells him on the plane his full name and his birthday, although he does not reply to the comments. When singing Come Fly With Us, Sierra and Cody sung together. In the "Pyramid Over Under" challenge, Sierra goes with Heather, but Sierra carries Cody out of the pyramid when they make it out and she is happy that they found him.

Sierra and Izzy then switch teams so that Sierra can be with Cody and Izzy can be with Owen.Before We Die, she says she wants to marry Cody and hugs him. When Sierra and Cody found out that they were paired up in the pinball challenge, she tackles him in delight.

In the second challenge after Team Amazon was arguing, Cody and Sierra decide to make their own video, which won the challenge. Sierra decided to have a group hug, but she wouldn't allow the other girls to hug Cody, possibly due to either them not helping, or because she's crazy about Cody. While Chris signs off the show, and shows a picture of Team Amazon, Sierra is shown hugging Cody's head.
Sierra is massaging Cody's feet during the flight to their next destination. Cody does not really want his feet to be touched, but Sierra ignores him and presses a pressure point to paralyze him. Once everyone arrives at the Yukon, Cody tries to cuddle Gwen for warmth, but she rejects him and Sierra hugs him instead. Later, as a polar bear tries to eat Owen and Cody, she throws chunks of ice at it, claiming she will not write an obituary for her Cody blog. She then grabs a large fish from the water and uses it as an oar and the ice she's standing on as a boat and rescues Cody. Due to him freezing, she spends most of the second half of the episode carrying him.
While on the flight, Sierra tries to warm up Cody by rubbing his legs, saying that whenever he has cold feet he'll think of her. To this he replies by saying "no kidding" in a disgusted tone. When climbing up the Statue of Liberty, Sierra wanted Cody to go before her so she could stare at his butt, saying it's, "The best view in New York" and purrs, to which Cody groans embarrassingly and tries to cover up.

When sliding down the thirty story fire pole, Sierra screamed Cody's name. Later, in Central Park, when Sierra picked up the large apple with her head in turtle pond, the Amazons cheered for her, while Cody replies "You're so weird!".
While in the Total Drama Jumbo Jet, Cody places a net with a bell system around him to alert him if Sierra is trying to rub his feet again as he sleeps. She instead lets him suck her thumb and watches him as he sleeps. When he awakens, they both scream until Sierra laughs at how cute Cody is when he's terrified, squeezing his cheek. Cody is then seen in the confessional scrubbing his tongue with a toothbrush, wondering if Sierra keeps her thumbs in her armpits when no one's looking. Sierra is seen in the confessional right afterward, saying Cody was into her (while having her thumbs stuck under her armpits). Later, Sierra makes a raw meat snowman of Cody, called "Meat Cody." This results in there not being enough meat for Team Amazon to win the challenge. During the dancing challenge, Cody, not wanting to wear lederhosen in front of Gwen, tells Sierra she'd look hot in it. This makes her want it really badly however Chris doesn't give it to her as a result, and makes Cody wear it instead. Sierra then sings a song on the dance platform about how much she loves Cody. When Cody later gets knocked off the dance platform during the challenge, Sierra shouts out his name and then angrily kicks DJ off the platform out of her worry for Cody. When Team Amazon wins the challenge, Sierra squeezes Cody in victory.Zing-Zings by Chef, Cody was bitten by a red ant, and had run out of the medication due to Gwen's accidental injection. Sierra offered to help by sucking the poison out of his thumb, which repulsed Cody, although he made no attempt to stop her. Later, when Team Amazon lost and had to vote someone off, Sierra voted with Gwen and Courtney and voted for Heather, but only if (seeing Gwen as competition) Gwen stopped being nice to Cody. At the Barf Bag Ceremony, Chris revealed the voting process, and it turned out that Cody voted for Sierra, frightened by her stalker-like behavior. This left Sierra heartbroken and confused, as she states in the Confessional that even after she gave him foot-rubs and kept "hair collections," he still voted for her. This implies that Sierra may lose some of her attraction, if not respect, for Cody.

He even has all of her favorite foods which he later states that they're his favorites, but knows Sierra eats off his plate. She states that she knows he isn't doing this because he wants to. Near the episode's end, Cody eventually tries harder to get through to her. He tells her to stop crying, and that he is starting to prefer her always annoying him instead of crying over him. Cody says that obsessed Sierra was like being "slapped in the face," while upset Sierra was like being "kicked in the chestnuts." Sierra accepted this and hugs him. In the confessional, she happily claimed that she loved the attention he finally gave her, and that she wasn't that mad at Cody, just playing hard-to-get to get him to pay more attention to her.
Throughout the episode, Sierra is constantly flirting with Cody. While relaxing in the first class section, Heather finds a toothbrush in the vent, which apparently belongs to Cody. Sierra states that she has been looking for it, and brushed her teeth with it, much to Cody's dismay since it was his last one. Later, when the contestants get thrown out of the plane into the water, Sierra is shown embracing Cody. During Sea Shanty Mix, Sierra and Cody were rowing and singing together. While Gwen and Courtney were climbing up a rock due to seeing a certain rock formation, which created an illusion that appeared to be Duncan, Sierra appears to be glad to be alone with Cody at last in the boat, in which she complimented how he smelled like toothpaste, which causes Cody to back up and fall into the water. After Gwen and Courtney were coming down from the rock, Sierra tells them a story about how much people want to see others, in which Cody wanted to end the story. She stated the before she even knew Cody, she saw him out her bedroom window on a white horse.

Later during the fighting challenge between Team Chris Is Really Really Really Hot and Team Amazon, Cody tries to help Courtney and Sierra, but Courtney calls Cody a pipsqueak and tells him to stay out of the fight. This infuriates Sierra to the point that she stops strangling Owen and attacks Courtney. While holding Courtney in a head-lock position, she tells Courtney to respect Cody. Cody tries to get both of his teammates to stop fighting, but Courtney slaps him away, which is enough for Sierra to tighten her grip and knock both herself and Courtney out.

While in Gwen's face boat, Sierra tried to make him happy. He started to vomit, but she embraced him anyway. When Team Chris Is Really Really Really Really Hot threw their cannon ball, Sierra saved Cody from it, getting hurt in her stomach in the process. He thanks her for this, making her happy. Once again in the confessional, she tells that she will absolutely have to do a surgery and will have to go through months of therapy. But when asking if it was worth it, she said that it was definitely worth it.
When all the contestants were on the boats in the river, just before they were about to go into the waterfall, Cody announced that he would let Sierra kiss him if they made it out alive, as "Like [they're] going to make it". Sierra hears this, and ties both the boats together and paddles incredibly fast. When they indeed make it onto land, Sierra kisses Cody. Cody, however, is repulsed, and brushes his teeth repeatedly. He even throws up in the bathroom confessional. Sierra was so excited that there is a possibility of "marrying" Cody as a challenge that she starts to hyperventilate.

Sierra is smiling at Cody while Cody is panicking in the loser cabin because they are supposedly married. During the race portion Sierra got Cody a donkey and later, while Cody was trying to tell her that he likes her as a friend, Sierra misunderstands thinking he meant he actually "like likes" her. After the donkey kicked her off the Great Wall, Sierra landed in an old lady's house who gave her some love tea. The tea is supposed to make one attractive to their crush just by drinking it. Cody desperately pleaded to Chris to ring the bell so Sierra would not be able to continue, but he was too late. During the eating challenge, Cody and Sierra were sitting next to each other while Sierra drank her love tea. When Chris said that whoever the winner of the eating challenge was allowed to have a guest, Sierra immediately thought about Cody. Sierra won and chose Cody as her guest. In first class Sierra poured tea over herself and leaned over to Cody. It turns out that Cody is allergic to the tea, but Sierra saved him by jabbing an EpiPen into him.
Sierra gives Cody more of the Love-Me Tea, which causes him to be put into a comatose state and even hallucinates, imagining Sierra to be a polar bear, which terrifies him.

Sierra forgives him, but it was a fake elimination, so Sierra stays in the game.elimination ceremony, Sierra put a hand on Cody's shoulder when he seemed nervous. Before the final choice was made, Sierra wanted to get Cody's cake so she could celebrate his birthday.

Sierra was upset that her chocolate cake for Cody was destroyed. After Chris eliminates Sierra out of anger for destroying his plane, Sierra tells Cody that he must win for both of them.
Cody digs up Sierra from the rubble and Sierra says she had a dream like that once. When he puts her down in the wheelchair, he says his opinion for her changed. He says at first he thought she was nothing more than a crazy fan, but now sees that she is a true friend. Sierra seems disappointed and asks Cody if they are possibly more than friends. Cody says that they are "best" friends, which Sierra accepts. When Cody was searching the debris in order to find some way of getting to Hawaii, Sierra asks if she could search with him, which Cody thinks about, but lets her. She inadvertently gave Cody an idea for a hot air balloon and wanted Cody to take her wheelchair, and to leave without her, which meant she would be left behind. Cody says that he will take Sierra with him because she helped him get to the final three. During the flight they helped each other and argued which Sierra pointed out that they are like an old married couple which left Cody horrified.

This allows Alejandro to push him into the water, eliminating him from the competition.

In the confessional, Cody admits that he misses Sierra and wished she was still there in the game when he was fighting with Alejandro in the tie-breaker.
When the old cast appears on a yacht, Sierra is clutching Cody tightly against her chest and grinning, while Cody, who used to be disturbed by this action before, is now smiling.
Throughout the episode, Sierra mentions Cody several times despite him not competing. These events occur when she yells "For Cody!" when she jumps off the helicopter and later the cliff and when Sierra picks a key that's shaped like Cody's head. Sierra even compares Gwen and Duncan's relationship to her's and Cody's saying "love is love".

She also begins referring to him as Cody, which disturbs him.someone had broke her phone as it contains her top 500 pictures of Cody in it. When Sam suggests to imagine Cody in her mind, she starts to hallucinate her teammates as having Cody's head. She eventually focuses her hallucinations on Cameron due to him somewhat resembling Cody, and thus starts referring to him either as Cody, or some combination of their names.
Before the challenge, Sierra is sobbing in her bunk bed as she is devastated that Cameron, who she still thinks is Cody, has been transferred to the other team. Zoey tries to console her but Sierra becomes severely agitated when she points out that she keeps calling Cameron "Codycam", and subsequently runs out of the cabin sobbing hysterically. During the challenge among the mutated wildlife, Sierra tries to get "Camdy" to team up with her in finding the eggs despite them being on two different teams, and begins panting over him like a dog before Gwen pulls him away, sending her into an emotional breakdown. She tries to partner with Duncan and ask whether can she call him Cody to no avail. Sierra later retrieves a mutated egg that hatches into a two-headed rat, who she adopts as her own and names "Cody 1" and "Cody 2", greatly disturbing everybody including Chris and Chef.
Sierra continues to care for "Cody 1" and "Cody 2", having made herself their adoptive mother despite their feral behavior. Later during the boxing challenge, Chris pits Sierra against the twins' real mother, much to her horror. Fearing the outcome, she entrusts the mutant twins to "Camdy", still thinking Cameron is Cody and then tells him he's breaking up with her and that it wouldn't have lasted. However, Sierra comes out of the match in one piece and once again leeches onto Cameron, taking back what she said before the match and still thinking him to be Cody. She also mentions how glad she'll be to be side by side with "Camdy" again when the merge comes about, much to Cameron's horror. The Heroes ultimately lose the challenge and the Villains are told to vote off one of the Heroes as a result. They all agree to vote off Sierra in part due to some strong insistence from Cameron, who tells Sierra that she has a real Cody back home who needs her.
