Courtney has a polarizing personality, but at her core, she thinks of herself as a born leader, which often leads to her not letting others have a chance to take control. Although she is extremely bossy, competitive, critical and even manipulative at times, she can be genuinely civil and polite to her fellow competitors. Such an example is in Jamaica Me Sweat, when Courtney is the only one to acknowledge the injured Izzy and Owen. As an overachiever, she has a tendency to overreact when things go wrong, and drives herself crazy in order to get what she wants. She has become notorious among the contestants for constantly reminding them of her counselor-in-training experience, resulting in their constant annoyance.
Throughout her four competing seasons, the severity of Courtney's behavior ranges from generally easygoing to extremely antagonistic. When she wants something, she will fight to the death to get it. However, sometimes her determination ultimately leads to her own destruction. Courtney has exceptional athletic abilities and is also capable of lifting amounts of weight much greater than her own. She has displayed in several instances that she values the prize money over even her closest relationships. Her skewed priorities coupled with her harsh tendencies have resulted in her becoming a very disliked contestant among her fellow competitors.
At first, Courtney comes off as quite a friendly person, greeting and comforting several of the other campers. However she leaves a bad impression on her team in the first challenge after refusing to jump off the cliff into shark-infested waters, which devastates her. She is continually plagued with bad luck throughout the challenge: she gets a splinter from the wooden crate and a swollen eye due to a bee-sting allergy. Her team's performance also leads her to take charge and her bossy nature only fuels her team's dislike of her. After her team loses, she is considered for elimination, due to failing to participate in the cliff jumping challenge. Her attempts to promote her valuable leadership skills are mostly futile. In the end, she narrowly escapes elimination through a stroke of pure luck due to Ezekiel carelessly making a couple sexist comments, thus sparing her from elimination.
From here on in, Courtney mostly takes over leadership of the Killer Bass, often bringing up her past counselor-in-training (C.I.T.) experience, though her team rarely listens to her due to her bossy nature. Her fellow teammate, Bridgette, is the closest person she has to a friend, though Courtney often berates her for her clumsiness that almost costs them challenges, including the time when she broke her violin in Not Quite Famous, and damaged their tent in The Sucky Outdoors. In addition, she doesn't seem to be supportive of Bridgette's apparent crush on Geoff, wondering why Bridgette would be interested in a person like him. Courtney harbors a huge dislike for Harold and doesn't seem to view him as a strong contestant despite him helping their team win twice. Courtney's attitude is also known by the Screaming Gophers and it soon develops into conflicts with some of them. She immediately clashes heads with Heather, who commented on her poor leadership, Gwen, whom she accidentally threw gruel at and did not apologize, and Lindsay, for liking her teammate, Tyler, as she believes that Lindsay is acting as a spy to root out information about her team from Tyler.
Her most significant interaction is her love-hate relationship with bad boy Duncan. Early on, the two of them clash on how to lead their team. Despite their arguments, Duncan is shown to take a liking towards her, often flirting with her and giving her pet names. Though Courtney claims that she has no feelings towards him whatsoever, it is clear that she too has feelings for him. This is first shown in Phobia Factor when Courtney helps Duncan in overcoming his fear, and hugging him after he succeeds, but pulls back when she realizes what she is doing. As the season progress, the two of them often find themselves together in challenges, with Courtney mocking Duncan and highlighting his flaws while he counteracts by telling her to admit that she likes him. Although Courtney views Duncan as a delinquent who loves to cause trouble, she realizes that he is actually a nice person in Who Can You Trust?, when she saw him finding a new bunny for DJ, after he became grief-stricken when Geoff loses the first one. Although Duncan denies his actions, Courtney agrees to keep it a secret, though she does end up telling a few people like Bridgette and Leshawna.
Throughout Basic Straining, Courtney has to scold Duncan for making fun of Harold or angering Chef. Although she claims that she doesn't want the team to be at a disadvantage, Duncan persists that she is actually doing this out of concern, much to her frustration. After Duncan is sent to the boathouse, Courtney paid him a visit. After a talking for some time, Duncan finally convinces Courtney to break some rules, and the two of them steal junk food from Chef's kitchen for themselves and their fellow campers. Soon, Courtney become hyperactive from the experience and couldn't stop laughing. After another private moment with Duncan, Courtney pulls Duncan and kisses him for the first time. Unfortunately, their time together is short as Courtney is eliminated after their team loss. This shocks everyone and Courtney demands a recount but Chris denies it and he and Chef drag her to the Boat of Losers. Courtney exclaims that she does not concede defeat, and how she was her team's only hope. As the boat sails off, Courtney and Duncan bids each other goodbye with Duncan giving her a farewell gift, a wooden skull that he carved. It is later revealed that Harold tampered with the votes in order to get back at Duncan for bullying him.
By Haute Camp-ture, Courtney has found out about Harold's actions and spends most of the episode hunting him down. She also reveals that she is attempting to sue the show for her unfair elimination, with the other contestants backing her up as her witnesses. However, no one seems to care of her ranting and simply ignores her. Ezekiel and Noah even tell her to stop complaining but she knocks the former with a lamppost and throws her drink at the latter. Lindsay on the other hand, tells her that she would had been voted off eventually since nobody likes her, shocking Courtney in disbelief. After she finds Harold, Courtney proceeds to beat up him and ends up tying him up with the lamppost. She reveals that she is supporting Duncan, but tries to hide her feelings. However, Izzy points out to her that everyone knows that "she is all over him" and Noah even compares her infatuation for Duncan with his dog "drooling over a rib-eye steak."
In the finale, Courtney is among those who side with Owen even before he announces the party he is going to throw if he wins. While the final two are crossing a ravine, she and Duncan argue about Gwen and Owen's current situation, with Courtney worrying about them while Duncan simply states that it will raise the show's ratings. After a while, the two begin to make out while denying their feelings for each other.
In Total Drama, Drama, Drama, Drama Island, Courtney is shown to be feeling despondent about losing her lawsuit against the show's producers for wrongful termination. However, after Chris announces the million dollar challenge, her mood improves drastically and immediately pulls Duncan into helping her by kissing him. Courtney displays a great change in personality in this episode, being more ruthless and obsessed with winning the money. Even after Duncan fought an alligator for her in order to retrieve the briefcase, Courtney abandons him when he sprains his ankle and is unable to continue. However, she loses the money to Izzy's group and gives chase until she slams into a large backdrop. To Courtney's surprise, she discovered that they are not really away from civilization after all. Chris then sent an intern to stop her but Courtney manages to steal the intern's hot air balloon. She soon catches Owen, Tyler, DJ, and Cody (who had the case at the time) on a dangling microphone, demanding the case in exchange for their safety. She threatens that she would let them fall to their deaths if they refused. Eventually, all five of them have to jump off the balloon, landing on the diving board with Bridgette, Geoff, Katie and Sadie. As the contestants fight over the briefcase, the plane piloted by Justin crashes into the board's support beams, sending Courtney and a few others into the pool of green jelly that she failed to enter earlier in the season. Ultimately, Courtney is among those who are not qualified for season two, which frustrates her greatly. Before the season ends, Courtney makes a final confessional about her plans for the show for scamming her out of the million dollars again.
[[File:DuncanIsGonnaPay.png|thumb|left|220px|Starting off in the aftermath shows, Courtney grows suspicious over Gwen and Duncan's relationship. Courtney initially does not compete in Total Drama Action, but, as seen in The Aftermath: I, she is trying to file another lawsuit over her elimination from Basic Straining. Courtney initially sides with Gwen in the Gwen-Trent debacle because she thinks that Trent is a "loser by choice," but after Trent explains his obsession with the number nine, she switches to Trent's side. Come the next aftermath she is under the belief that Gwen is trying to steal Duncan from her, even after Gwen insists that they are "just friends." When Geoff shows an exclusive clip, although Courtney is initially relieved to see that Duncan is still thinking about her, a later scene in the clip that shows the two playfully wrestling and almost kissing angers her further, even though Gwen insists that it was a mistake.
[[File:Vhd.png|thumb|220px|Courtney debuts onto the competition, shocking Duncan.]] Courtney ends up winning her lawsuit against the show and debuts into the competition in Ocean's Eight - Or Nine, playing the role as the bank teller. After she rewards the loot to the Screaming Gaffers, Chris places her on the Killer Grips as a consolation prize. Even though she immediately takes leadership of her team, none of them get along with her due her bossiness and likewise, she thinks that they are a team of duds. To further solidify her team's dislike of her, they all voted for her despite her immunity. As a result, only Courtney's vote counts and Owen is eliminated.
During her stay, Courtney takes over Justin's role of the antagonist of the season. While she is still bossy and doesn't like not being in the leadership role, she is more ruthless and mean compared to the previous season and makes only enemies, partially due to her unfair advantages. Her main advantage is through her PDA, which she uses to keep contact with the outside world and threaten Chris into getting what she wants. Even though she had already earned the hatred of her team with her bossiness, the other team also quickly grew to dislike her for similar reasons, including Duncan. While they still show a mutual attraction to each other, because neither are on the same team at any point, Courtney is far more focused on the competition than the relationship, sometimes taking advantage of this fact. An example of this is in One Million Bucks, B.C., where when the two seem like they are about to kiss, Courtney knocks him off of the pillar by hitting him in the groin with the bone provided in the challenge, which let her team win their first challenge since The Chefshank Redemption. When they are pitted against each other again in the next episode, Courtney almost has no issues defeating Duncan at all in the Greco-Roman wrestling match.
Despite having very few allies after the merge, which happens shortly after her return, she still performs well in the majority of challenges, and manages to avoid elimination by repeatedly getting immunity. Although most of the contestants have their fair share of issues during the first post-merge challenge, Courtney easily maneuvers through the lasers and gets the reward by doing a flying kick in order to break the glass. When Chris reveals that the first reward will be used in order to escape the building, Courtney refuses to share her reward with the other contestants unless they give her something for it, much to the disbelief of the others. Although they are all reluctant to do so, they eventually agree to split the money with her 50-50, although this deal is cancelled later on when the contestants refuse to make room for her in the tomato soup (which was used to get the smell of the stink bombs off) unless she undoes the deal.
Her most noted enemy for most of her return is arguably Lindsay, who she openly dislikes. From the beginning, the two did not get along due to Courtney quickly taking the leadership role from her, and Courtney tends to get very frustrated by her lack of competence. An example of this is after both win a section of the challenge in Dial M for Merger, she outright states she doesn't like her and tries to get out of the Lame-o-sine in order to avoid going to a local cheese factory with her. She still does not get along with her in the following episode, and appears quite jealous towards her when she performs better in the first challenge. Despite this, she manages to win the next part challenge in order to receive immunity. From the discussion from the other contestants, it is likely that, had she not won the challenge, she would have been voted off by everyone except for Duncan. She begins to become impatient with her at the beginning of The Princess Pride when they both are trying out for the role of the princess, but Courtney is the one that ends up getting the role. Because of this, she doesn't have to do most of the challenge, but she manages to win over Justin after she sings. Despite Justin's attraction to her, however, Courtney manages to defeat him in the sword fight at the end, admitting that she was never actually attracted to him at all once he was eliminated.
Courtney's first post-merge loss comes at the hands of Lindsay in Get a Clue. She becomes impatient over getting rewards during the challenge, she demands a prize after doing more than necessary for the challenge. Chris eventually gives her cheese puffs in order to shut her up. During the actual challenge, while most of the other contestants begin to panic over Chris's alleged murder, Courtney insists it is all a set-up and tries to get other contestants to help prove her point. Even after Duncan proves to her that it was, in fact, a real train, Courtney focuses on stopping the train rather than solving the murder mystery. While she is correct in her conclusion that the murder didn't actually happen, Lindsay reasons that Courtney was the murderer, which Chris decided was true. Despite this, Courtney's win streak isn't broken for long, as she ends up winning invincibility once again in Rock n' Rule. Courtney tries very hard in the guitar playing challenge, but Chris states she was trying "too hard", and that Duncan played more like a real rock star would. While in the second challenge she mistakenly avoids the paparazzi when the goal was to let them get photo shoots, so Lindsay ends up winning. This causes her to go ballistic during the last challenge, and completely destroys the set for the hotel room, so that when Lindsay's extra seconds she won from the last challenge starts, there is nothing left for her to destroy.
Due to Lindsay's elimination, Courtney tries to get the only other female left, Beth, in an alliance with her. While Beth is aware that Courtney is trying to do this, Courtney is also aware that she will have to do anything to get in an alliance with her. As a result, when the two are forced to cook the "seven deadliest species of fish known to man," Courtney lets Beth use her PDA to call Brady while she did all of the hard work, something that manages to create an alliance between the two by the end of the episode. This alliance, however, didn't make it through the next episode when Courtney refuses to listen to her warning that going last in the Vomit Comet would prove to be a bad idea when Beth refuses to forfeit the challenge alongside her once it was filled with barf. After an intense argument, the two end their alliance, and Courtney's immunity streak is broken for good.
Courtney and Duncan finally go back to being a couple in Top Dog when Courtney writes a 32 page letter outlining his faults, something that she is very insistent on Duncan following. During the challenge, Courtney had a lot of issues dealing with her animal buddy, which was a shark, especially after Owen caused it to go crazy by making it see blood. She continues to fight it during the second challenge, along with a few more sharks, and ends up losing her PDA, which is not returned to her until she returns to the film lot two days later. Courtney ends up getting voted off that night, not only by Beth but Duncan as well, with his reason being that her popularity was declining and he didn't want her dragging him down along with the aforementioned letter. This causes her to terminate their relationship once again. In the exclusive clip, Courtney reveals that she will get fifty percent of the prize money if Duncan wins due to the contract he signed. She attempts to call her lawyers only to find out that they are not available and angrily throws her PDA out of the window. Courtney however, is confident that she can go through without her lawyers as she still has her documents that "holds her entire future." Suddenly, a breeze blows the documents out of the window, causing Courtney to scream in agony.
Despite her frustration with him, Courtney is still Duncan's biggest supporter in The Aftermath: IV, attempting to advocate things such as an "unbiased" quiz to determine the winner. Due to time constraints, she is unable to ask a question to either of the finalists, but ends up voting for Duncan regardless. Regardless of who wins the season, she ends up getting back together with Duncan, but come the events of Celebrity Manhunt's Total Drama Action Reunion Special, they broke up again due to a fight they had at dinner and a custody fight over a pet raccoon they owned. Courtney was the one that drove the bus when the cast chases down the Total Drama Dirtbags bus, but when Duncan and Courtney began to make out after suddenly getting back together again, she loses her focus and drives the bus off a cliff. She is among the contestants that are saved behind and eventually saved by Chris, letting her qualify for Total Drama World Tour. In her final confessional of the season, she states her goal is to keep a much closer eye on Gwen, still feeling suspicious about her feelings towards Duncan.
Courtney is introduced with the rest of the cast in Walk Like An Egyptian - Part 1. She and Duncan have apparently gotten back together, but she is still wary of Duncan and Gwen's rather flirtatious relationship. Courtney is thrilled to be able to sing in front of the show's massive viewing audience, unlike her fellow contestants. She later prepares a belay for her and Duncan so they can complete the "Pyramid Over Under" challenge. Gwen ends up joining the group, much to Courtney's dismay. The girls' constant bickering pushes Duncan to his limit. He quits the show and storms back to the plane to await a ride home. Courtney and Gwen stare at him, mouths agape, but neither actually go after him. Courtney then joins her team with Gwen, Heather, Cody, and Izzy, which they name Team Amazon. In the next episode, she and Heather clash automatically over leadership. They are later on the same page as they engage in taunting Team Chris Is Really Really Really Really Hot while the teams travel to the Nile River. Courtney states her loyalty to Duncan despite his rash decision. However, she does stop to consider Alejandro's question of if he even appreciates her.
Throughout the next few episodes, Courtney continues to lock horns with Heather and Gwen. Her distaste for the former especially intensifies. This is due to Heather's constant bossing around of her teammates and desperation to prove that she is valuable, along with whipping Courtney in Anything Yukon Do, I Can Do Better and her lack of consideration for the team's reward in Broadway, Baby! Courtney makes an agreement with Gwen to vote Heather off the first time they are sent to an elimination ceremony, which they try, but fail. Now with some common ground, the two finally begin to develop a camaraderie.
In Newf Kids on the Rock, Courtney leads Cody and Sierra in rowing Team Amazon's boat to shore. She and Gwen stop their team's boat after seeing what they think is Duncan, but is only a rock formation. Sierra explains when they get down from climbing that Courtney thought she saw Duncan because she misses him. Courtney accepts this, but her suspicions of Gwen and Duncan return as she wonders what reason the former had to see him as well. When Team Amazon finally catch up the everyone else, Heather blames Courtney for the failure. Gwen, however, volunteers to take responsibility herself, which surprises Courtney.
In the next episode, Courtney and Heather are paired up to do the bobsled challenge together. Courtney tells the latter that her lawyers have ensured that she is protected from deadly stunts. In Heather's case, however, she isn't sure. Before Heather can object, Courtney launches them into the challenge. In I See London..., she and Gwen spend the episode getting to know each other and using their shared skills and knowledge to work through the challenges. Courtney admits in the confessional that she is, indeed, growing fond of Gwen. However, she is still timid about having a friendship with her. When Gwen complains about her sunburn, Courtney gives her a remedy made out of bat guano, which helps. Later in the episode, Gwen and Courtney arrive at a punk club where they find Duncan and capture him, which causes Team Amazon to win the challenge. Before the elimination ceremony, Courtney scolds Duncan for "abandoning" her. She then hugs him and clarifies that she isn't mad, she just missed him.
In Greece's Pieces, Courtney continues her friendly interactions with Gwen, as well as her belief that there is something going on between Gwen and Duncan. Gwen is feeling guilty for having kissed Duncan behind her back, but plays along with Courtney's excitement uncomfortably. Courtney shows her a list of things that she intends to change about Duncan, so he can be perfect. Prior to the tie-breaking challenge, Tyler is forced by Alejandro to admit that he saw Duncan and Gwen kissing. Courtney lashes out at Gwen for betraying her trust. She then orders Cody to throw the challenge so the team can vote Gwen out. Cody's devotion to Gwen makes him do otherwise, and Team Amazon wins. Afterwards, Courtney sobs to Heather's attempts at comfort. In the next episode, Courtney has far from forgiven Gwen and Duncan for their actions. She breaks up with him, tries flirting with Tyler to make him jealous, and is determined to lose the challenge so Gwen can be eliminated. She leads the episode's song about her betrayal, Boyfriend Kisser. Courtney constantly tries to sabotage her team's progress so that Team Amazon loses and she can have Gwen voted off. Near the end of the challenge, Courtney trips Gwen in order to break the device Gwen is holding but to no avail. At the end of the episode, enraged that not only Gwen is safe but Duncan as well, Courtney tosses Tyler out of the plane. She makes it her mission to throw the challenge to vote off Gwen through the entirety of Picnic at Hanging Dork, to the chagrin of Heather. When they finally lose the challenge, the votes are a tie between her and Gwen, which lead to them to compete in a tiebreaker, which Courtney won, and Gwen lost.
Alejandro begins flirting with Courtney as part of his and Duncan's plan to turn the girls against each other. Courtney is taken aback by his sudden interest, and becomes smitten with him. In Sweden Sour, Courtney begins responding to Alejandro's advances, and seems to have actually fallen for him, as their flirting takes place away from Duncan. Alejandro notes that manipulating Courtney normally would be a lot harder, but her skewed emotions have given him the edge. He then states that he plans to eventually betray her. Later, after Courtney tries unsuccessfully to fish an apology from Duncan, Alejandro plots with her so they can "drive Duncan crazy." She clashes with Heather throughout the episode's challenges as they compete for team leader, and because both have an infatuation with Alejandro. Team Amazon take another loss, and Courtney's teammates decide unanimously to vote her off, but as it is a fake ceremony, Courtney is safe, much to the disapproval of her teammates.
In the next episode, Courtney and Duncan are at odds once again as they are paired for the wedding challenge. She even considers of teaming up with the bear that she originally chose. Duncan purposely directs her off course during the first challenge leading her to trip or bump into every obstacles. Despite this, Duncan and Courtney easily pass customs after everyone else falls into the water and win immunity. In Chinese Fake-Out, Courtney begins ignoring Duncan for the most part. During the first part of the challenge, a race around the great wall, she ends up owing Alejandro a favor, after he assists her when her tricycle gets stuck. He later figures out how she can repay her debt just before the eating challenge, when she reveals that she has a strong stomach. Alejandro slips Courtney the disgusting food underneath the table until Heather and Duncan inform Chris of the cheating. He forces Courtney to wear a lion dancer's mask to prevent her from eating anymore. When Chris states that the final vote is a tie between Courtney and Blaineley, she is ready for any tie-breaker challenge he throws at her. Due to the budget, Chris simply eliminates them both. In the exclusive clip, Courtney complains about her elimination during her drop. But she then states that she is happy to get rid of Blaineley and be far away from Duncan. Courtney soon realizes she is too close to the ground and tries to pull her parachute, but it doesn't release and she crashes into an elderly Chinese woman's roof. Angered, the old woman throws a hammer at Courtney right before the clip ends.
In Hawaiian Style, along with continuing to express her hatred for Duncan and Gwen, Courtney supports Alejandro to win. She performs in the challenge in order to gain a special advantage for him. She surfs against Harold and Blaineley and wins first place, her garland falling around the neck of Alejandro's spirit animal, a jaguar, after she wipes out. Alejandro earns a wheelbarrow, which Bridgette and Geoff clarify will be useful in the final challenge. In Hawaiian Punch, Alejandro chooses her to assist him in the volcano challenge. She and Lindsay help to build his dummy and hinder Heather's helpers, Cody and Harold. At one point, she accidentally traps Alejandro due to any lack of indication which trap is which. She is the only one visibly unhappy by Heather's win in her ending. Once the volcano erupts, she follows the cast down the path and into the water, where they frantically swim to safety.
In Bigger! Badder! Brutal-er!, Courtney appears on the yacht with the other veterans. While Alejandro (still in the Drama Machine) has Heather in his arms nearby, she glares angrily at them from behind Geoff and Bridgette.
Courtney returns to Total Drama All-Stars as one of the seven original campers, and picks up her conflict with Gwen and Duncan from third season. Despite having multiple villainous deeds from her previous seasons, she is still placed on the Heroic Hamsters. However, she shows very little heroic qualities while she is on the team. She quickly starts a conflict with most of her teammates, mostly by bossing them around, taking credit for many of their ideas, and being frustrated due to getting along with each other so well. She often plans to eliminate her team members such as Zoey rather early on and often threatens them when they are not doing very well in challenges. Saving Private Leechball eventually becomes her undoing, as she stays back with Sam in order to not participate in the challenge. She uses the excuse that since she didn't bring any breakfast to him, she would make up for it by protecting him. In reality, she simply wanted to lay back and let the "foot soldiers take leeches to the face". When Jo eventually finds their hiding spot, she uses him as a human shield in order to defend herself, making the excuse that anyone would do the same. Due to this act of cowardice, Chris makes her switch teams with Duncan to become a part of the Villainous Vultures.
Due to the team transfer, she attempts to find an ally in Food Fright. She finds Scott to be a potential alliance member and learns that Gwen actually does want to be friends with her again, despite Courtney's beliefs that she was faking it due to all of the times in earlier episodes in which Gwen would accidentally injure Courtney. Despite the knowledge of Gwen's true intentions, she still despises her, making a deal with Heather to vote her off if they lose the challenge. Things only seem to get worse in Moon Madness, in which Courtney seems to have no qualms if Gwen dies, barely showing any appreciation when she saves her from being attacked by a deer. Once Gwen tells Courtney that she had broken up with Duncan, however, Courtney accepts her apology and they manage to get along once again. However in Suckers Punched, Chris rigs the challenge to have her and Gwen fight each other. Although both girls initially refuse to fight each other, Chris motivates Courtney by showing some videos of Duncan and Gwen kissing from Sierra's blog, leading her to angrily attack Gwen. By the end of the match it appears that the two had vented out all their anger, causing their friendship to officially be renewed and letting their team win the challenge. The two willingly pair up in You Regatta Be Kidding Me despite Chris saying that only one person could win immunity for it, acting unusually friendly towards each other as well as promising to take each other to the finale.
Even though things started off a bit rocky with Gwen before getting better, things with Scott start out much smoother. Despite Courtney not seeing anything in him initially past the alliance, both of them quickly develop feelings towards each other when Scott shows attraction towards her bossiness. This ordeal happens rather quickly, as the two are already shown to have a mutual attraction towards one another, starting in the very episode that they meet. While Scott is exiled to Boney Island for the night, Courtney is seen saddened by his absence. She is concerned about his well being and relieves herself of worry once he arrives unscathed. The two of them work together during the challenge in No One Eggspects The Spanish Opposition. They then eventually share a kiss in Zeek And Ye Shall Find and start an official relationship, but it does not last very long due to "Mike's" interference, as he persuades Cameron to kiss Courtney. Even though this was all set up by the two with no intentions from Courtney, Scott is under the impression that the opposite had happened. This results in their break-up a mere two hours after agreeing to a relationship. They continue to quarrel even after they are captured by Ezekiel.
After seeing Scott heartbroken over recent events, Courtney demands that they get back together in The Obsta-Kill Kourse, to which he agrees. While Scott gets quite a bit of help from Courtney during the challenge, she still constantly ridicules him whenever he needs help or messes up. As for the kiss with Cameron, Courtney accidentally tells Gwen herself, whilst warning Zoey not to do so. This upsets her due to hypocrisy on Courtney's part, but she doesn't seem to hold too much of a grudge against her for it. Courtney still promises to take Gwen to the finale, but in actuality, she plans to eliminate her, Zoey, and Mike, and bring Scott instead. This is not due to her feelings for him, but because she thinks that he will eventually throw the challenge for her, securing Courtney's victory for the season. She outlines this plan on a chart for her own convenience. However, Courtney was apparently rather careless with it, because Mal exposes this chart to Gwen, Zoey and Scott in Sundae Muddy Sundae, causing them to turn against her. While she gives almost no sympathy for Scott whatsoever during the challenge, she still tries to rekindle her friendship with Gwen, who only wants to do so if Courtney decides to vote herself off. She is behind for a large portion of the challenge, but she manages to cross the finish line first, under the impression that the interns would be hungry enough to eat her sundae, which had been covered in burnt chocolate and bird vomit. Chris then changes the rules to having to be the first one to eat their own sundae, which she fails to do. She ends up being eliminated that night in a 3-2 vote, but whether she listened to Gwen's request and voted herself off or not is unknown. In the exclusive clip, Courtney ends up somewhere in the sea close to a beach and is surrounded by two sharks. She tries to offer her sundae to them but they are disgusted by its stench and vomit on her. In The Final Wreck-ening, Courtney is seen inside one of the balloons, though she floats away with the others before an intern can get her down.
The teenage Courtney makes a cameo appearance in Sharing is Caring in an imagine spot when her younger self explains her plan to sell her rare toy in the future.
