These two characters are complete opposites in appearance and personality. Geoff is an upbeat guy in bright, revealing clothes with light, naturally-colored hair who likes to party. In contrast, Gwen is serious in nature, prefers to be left in solitude and dresses in dark, non-revealing clothing complete with matching dark, dyed hair. Towards the beginning, Gwen is rather unkind to Geoff. However, towards the end of Total Drama Island, Gwen grows to appreciate Geoff and see him as a friend, as opposed to her previous perception of him as a mindless party animal. Their interaction in Trial by Tri-Armed Triathlon, is an important turning point in Gwen's life, when Geoff helps her realize that she doesn't have to be anyone but herself. She understands that being Gwen doesn't have to mean being miserable all the time, and that it can also mean having fun, being crazy, being loose, and taking chances, which behind Gwen's reserved façade, is a side of herself she has, but is often too afraid to show. This may also hint that Gwen won't always be goth, because in truth, her heart is just not into it, and more into being herself, without a stereotype to limit her.
Since this episode, Gwen becomes notably annoyed with Geoff's relaxed attitude, especially disliking his "abuse" of words such as "dude" and "man", even commenting that if Geoff or Chris repeated those words, she'd puke.
Gwen and Geoff are the final two contestants from their respective teams that survive Chef Hatchet's boot camp. Their final challenge is to hang upside-down from a tree for as long as possible without falling off. As their teammates cheered them on, Gwen claims she could hang on the tree all day long, to which Geoff enthusiastically shouts, "Rock on, sister!" being rather friendly about the competition even though it had come down to just the two of them. Despite claiming to "live for the head-rush" that comes with hanging upside-down, Geoff passes out soon afterwards and Gwen wins the challenge for her team.
While talking to Bridgette, Gwen recollects Geoff trying to showoff to Bridgette but ends up crashing into the dock. After the girls find a love letter in the form of a haiku, Gwen jokes Geoff can't be the writer since he probably couldn't even spell haiku. However, this angers Bridgette and leads to the girls having a minor feud, where the two try to find out who wrote the love letter. Gwen considers Geoff as a "skater flake" and does not believe he is very intelligent. Gwen's suspicions are confirmed when Bridgette discovers Geoff doesn't even know what a haiku is.
When Gwen wins the reward, Geoff, along with Leshawna, angrily stares at her and Gwen states that they are just jealous.
It is revealed that Geoff feels that both Duncan and Gwen are gloomy and too serious. Gwen still finds Geoff too cheerful, even claiming that he was the camper annoying her the most on the island at that point, possibly even more than Heather, due to his upbeat, partying attitude, saying that he's always happy. Geoff and Gwen are then paired together for that episode's challenge. Geoff begins telling her a tale of when he and his friend Jay were causing shenanigans during a party and received the longest detention in his school's history, though Gwen tells him numerous times that she doesn't care about what he says.
When they get to the island, Duncan and Leshawna begin wrestling over her weight and Geoff comments on how they are like milk and grape juice on how they contradict each other. When Gwen begins yelling at him of how they were in the middle of the challenge, Geoff motions to his back and lets Gwen ride, to Gwen's surprise and pleasure. Later, Gwen snaps at him for not taking the challenge seriously, throwing his camera into the lake. Geoff reveals that he always wanted to befriend Gwen, but felt that she was not the type who would be interested in partying, though he assured her that if they went to the same high school, he would have invited her to all of his parties. Gwen admits that she sometimes wished she could be more cheerful and "normal" like other girls, and also sadly states she had never attended a party, to Geoff's horror. She shrugs it off as the whole thing not being part of her DNA until Geoff corrects her, saying partying and being upbeat is more like a state of mind. When Geoff manages to open Gwen's eyes to a new way of looking at life, she slowly warms up to him.
After they win the second challenge, Gwen was successfully shouting out in victory like Geoff. Though they lost the third challenge, Gwen has fully warmed up to Geoff and genuinely has fun with him. This leads to Gwen becoming upset when Geoff gets voted off in the same episode, solely because he was too nice, and the other contestants considered his popularity a threat. Geoff, however, took his loss in stride. He is stopped by Gwen before boarding the Boat of Losers, where she gave back his camera that she had thrown into the lake earlier that day. She admits she went back to Boney Island to retrieve it and thanked Geoff for all he did for her. Geoff catches Gwen in the moment and snapped a picture of the two of them at the very end of the episode, seeming to symbolize that the two had made peace with each other.
Gwen lists off the five "sane" people on the show she actually liked, Geoff is not one of them. Gwen calls Geoff a "party-obsessed jerk" even though they had become friends a few episodes prior. Geoff was on Owen's side from the very beginning which may have been due to his love for parties.
In a bizarre contrast to the previous Aftermath, Geoff now openly criticizes Gwen for breaking up with Trent, even more than Bridgette to boost the ratings. Gwen tries to drive away from the subject, but Geoff presses on. He goes so far as showing a clip of Gwen and Duncan allegedly almost kiss, because the video features Duncan playfully wrestling her to the ground a short distance away from her lips.
This infuriates Courtney and makes Gwen look bad, even as she struggles to explain that they are nothing more than friends. The events of this episode force Gwen herself to question her friendship with Geoff. She even asks him about it, to which he responds that his new gig 'trumps' the times that he and Gwen made s'mores. Later, Geoff tries to force Gwen to sit in a dunk tank full of piranhas just for his own amusement. This brazen act is only stopped by Trent sticking up for Gwen and Izzy causing Chef to fall in instead.
Gwen is angry at Geoff for wanting to put Owen in the electric chair.
Throughout the episode, Geoff repeatedly stops Courtney from singing her hateful song about Gwen and Duncan.
As seen in the unfinished prototype version of Total Drama Island, Gwen and Geoff were originally supposed to be love interests to each other, rather than platonic friends. However, this was eventually cut. Gwen is seen sleeping on Geoff's chest while the two sit on a lounge chair by the docks in the Camp TV promo. Additionally, Geoff has his hand around her waist on the promotional poster.
