Duncan and Gwen

The Gwen-Duncan Relationship, also known as "Gwuncan" by Sierra and fans, is the romantic relationship between Gwen and Duncan. This friendship/relationship became quite popular since the beginning of Total Drama Action, and was strongly hinted at being a full-on relationship throughout Total Drama World Tour. The relationship was confirmed to be romantic in I See London.... They officially became a couple in The Ex-Files.

Overview
Before Total Drama World Tour, the relationship between Gwen and Duncan was viewed as an unofficial relationship. They have a lot in common, and seemed to be very close friends in Total Drama Action. Although both of them initially denied attraction to each other, Gwen and Duncan know some personal details about each other, and it has not been explained to viewers how they know these details. Also, their friendship has caused jealousy to arise in their respective romantic partners, Trent and Courtney, which has led to unpleasant punishments in these relationships (especially in the case of Trent). Around the time Total Drama World Tour started, Duncan had clearly begun a romantic interest in Gwen while she also had some feelings for him. The mutual understanding in this began with their first kiss in I See London.... However, there are several complications in the attraction. Gwen is still confused and unsure about a relationship with Duncan, and Duncan is still dating Courtney. Duncan, however, appears to have lost interest in Courtney, choosing to pursue a romance with Gwen instead. In Greece's Pieces, Gwen admitted that she thought that the kiss was great, and didn't care much for Courtney's feelings; her only concern was that both of them would undoubtedly be voted out soon due to the scandal. In The Ex-Files, after Duncan officially broke up with Courtney, Gwen was still suspicious that Duncan was bothered by Tyler and Courtney flirting, even though he wasn't. However, following a second kiss between the two, Gwen settles on middle ground, saying that they will let things happen without plans, and he seems to agree and tells her that's the reason why he likes her. Despite her elimination in Picnic at Hanging Dork, along with the fact that she noticeably seemed upset by Duncan's sad reaction to Courtney and Alejando flirting (even though Duncan was pretending to just to fool Courtney), she and Duncan still remained a couple, with Gwe reminding Courtney about this moments before she fell. Duncan did not forget about her when she left; he carved a picture of her face on the side of one of the first-class seats in Sweden Sour. For the rest of the season, save for several tirades and mentions of the fiasco by Courtney, the relationship wasn't referred to again, thus leaving it assumed that they stayed together.

Not So Happy Campers - Part 1
When Tyler said "At least you don't have to sleep next to him," Gwen looks intimidated by him. Gwen was impressed when Duncan slices a cockroach in half using an axe.

The Big Sleep
Gwen and Duncan are the remaining two campers out of twenty-one who remain awake during the Awake-a-Thon. After Chris McLean offers a bathroom break, Duncan assures Gwen he can hold it all day and calls her "sweetheart" (though this may not mean much, as he uses terms of endearment such as this on most girls). Gwen asks Duncan if he could hold it after another ten chapters of a Canadian history book, and this challenge makes Duncan surrender and use the bathroom, where he later fell asleep.

Who Can You Trust?
During the rock climb challenge, Heather pulls a prank on Gwen that causes her to lose her skirt while climbing the mountain, leaving Gwen with her panties fully viewable to everyone watching the challenge. Duncan is notably seen commenting on the scene and seems very satisfied with what he sees, with Chris agreeing with him. Despite this, there is no reaction shown from Trent.

No Pain, No Game
Gwen showed particular horror in Duncan being forced to defend himself against snapping turtles that Trent had to snap her out of it and apologize for what had happened in Phobia Factor between the two of them.

X-Treme Torture
When trying to figure out with Bridgette who wrote the haiku while assuming it could have been for her, Gwen immediately rules Duncan out because he has Courtney, but this could have merely been an assumption due to the events of the previous episode.

Hide and Be Sneaky
When Bridgette suggests they vote off Duncan and LeShawna says that she doesn't trust him, Gwen nodded her head and agreed.

That's Off the Chain!
Duncan and Gwen were playing catch with a frisbee in the beginning. Then, when Duncan goes to check on Geoff, Gwen says, "Since when did he have a heart?", implying she was noticing his soft side without knowing about DJ's bunny.

Hook, Line, and Screamer
Both Duncan and Gwen enjoy the gory movie that the other campers seemed horrified to watch, excluding Izzy, talking with one another about their favorite gore scenes from other slasher flicks. Heather insults both of them, saying they actually have more in common than "bad fashion sense". Their knowledge in slasher movies allow them to be the final two campers remaining in the contest, although Duncan appears to trick Gwen into leaving the campfire so that he could face the killer and win. Gwen, however, did seem to be interested in why Duncan went to Juvenile Hall.

Duncan is the first one to be terrified when he saw that Gwen was facing the real psycho killer, and like everyone else, rushed to warn her of the danger. He congratulated her with a high five when she successfully fought off the killer. When DJ was eliminated, Gwen and Duncan were standing next to each other, and Gwen had her arm draped over Duncan's back.

Camp Castaways
When it comes down to the final four, Duncan takes delight in watching Gwen and Heather fight. Duncan said in the confessional that he said it was great to be stuck on an island with two hot chicks (Heather and Gwen) but he then backed it up by saying that they were both "completely insane. They spend most of the episode arguing over what to do when they are suddenly stranded on a deserted island. Eventually, Gwen makes a raft so she can get herself off the island, but has no food. Duncan, meanwhile, had food, but no way out of the island. Duncan traded Gwen his egg to hitch a ride with her, as they both happily left Heather behind. They argue a bit while paddling across the lake, with Duncan insisting that Gwen had no idea where she was going (which was proven to be true when Gwen accidentally paddled back to the same island they just left, only in a different area). Duncan takes his egg back as he runs off from Gwen, but is soon attacked by the monstrous mother bird (somewhat resembling a Canadian Goose) that wants the egg. After a brief moment where they try to give the egg back to each other, Duncan is carried off by the mother bird. Gwen actually uses a rope in an attempt to save Duncan, but ends up getting pulled up into the air as well, and they both ride haphazardly on the bird until they meet back up with Heather and Owen. Also when the snake fell on them all four campers were terrified and ran up to the tree house.

At the suggestion of Owen, all four campers sat in the tree house and confessed their sins. It was at this point that Gwen finally found out why Duncan went to Juvenile Hall, but the exact details are unknown to the viewer.

Are We There Yeti?
After Duncan is eliminated, Gwen tells him that he played the game well, and that she was sorry he had to lose over something as trivial as sticky buns (which was actually Owen's fault). They bump knuckles as a sign of their friendship. Even though they spent most of this episode playing tricks on each other (due to being on different teams), it appears that it was this episode where Duncan and Gwen officially respected each other as competitors and decent people. Gwen was the only one of the three who parted with Duncan on a good note.

The Very Last Episode, Really!
Gwen did not consider Duncan as one of the sane people, calling Duncan psychotic, though not to his face. Duncan was on Owen's side from the beginning rather than Gwen's, even before Owen announced his plans for the party. Also, when Gwen was crossing the beam and the eagle attacked her, Duncan laughed and said that Gwen's near death was awesome TV action. However, his intentions seemed more to annoy/impress Courtney than to criticize Gwen.

Alien Resurr-eggtion
Trent starts to grow jealous of Duncan due to Duncan and Gwen's budding friendship. Gwen tells Duncan he is skinny in her own way at breakfast by saying that he could use the extra carbs when Duncan tries to offer Gwen his toast. Though having almost no history of conflict with him before, Trent is quick to say nasty things behind Duncan's back in the confessional stall when he becomes wary of Duncan and Gwen getting along too well for his liking. Trent attempts to fit in with Duncan and Gwen's conversations about obscure alien movies, but both of them see right through him. They also seem eager to take the alien down together, with Trent trailing behind. However, near the end of the episode, Duncan is eliminated in the challenge. Gwen pokes fun at him for losing, which Duncan laughs off (Trent liked to view the exchange as more malicious on Gwen's end than it really was). When Trent is forced to choose to save either one of the last alien eggs or Gwen's lucky necklace, he chooses the necklace. Duncan admits he would have gone for the egg. When Gwen gives Trent her necklace for good luck, Duncan subtly makes fun of Trent's sensitivity, being somewhat of hypocrite, since he had given Courtney a sappy gift.

Riot On Set
When choosing teams, Gwen chose Duncan first, which upset Trent, and pleases Duncan. After Gwen picks Duncan and LeShawna while Trent picks Lindsay and Justin, Gwen says, "Oh, pick all the good looking people!" Duncan and LeShawna glare at her. Here she openly says that Duncan is not good looking. However, this could also be taken to mean that Gwen thinks Trent is picking the most attractive people. Throughout the episode, Trent shows disapproval for every time the two interact, such as when Duncan catches Gwen when she falls. On the set of the challenge, Gwen motivates Duncan to do the challenge by telling him that he is 'hot, sexy, and stud-like'. At the end of the episode, Gwen tells Trent not to worry about Duncan, assuring him that Duncan is "no Trent." She also mentions that Duncan still has a picture of Courtney under his pillow, though it is unknown how she would know something so personal, as Duncan is known for being reserved and going out of his way to hide anything that trivializes his rough and tough exterior.

Beach Blanket Bogus
At the beginning of the episode, Duncan laughs after his successful prank, in which Trent's saltshaker spills onto his eggs, resulting in an angry slap from Gwen calling him a third-grader. Later, at the surf board balance challenge, the two share a laugh over Harold's rant about his butt.

When Duncan wins the challenge for the Screaming Gaffers, they slap fists, then share a brief friendly hug, which makes Trent call the team a "ticking time bomb of betrayal". After they return to Camp Wawanakwa, Gwen and Duncan sneak off together during the sand castle challenge in order to take apart the bus they used to get there so they could sleep in the cabins.

Later, while Gwen is stressing over Trent's sudden strange actions and believing she's to blame for them, Duncan tells her that she is giving herself too much credit, though he later points out that Trent's mild insanity over his obsession with the number nine could very well be the fact that the four letters in Gwen's name plus five in Trent's equal nine overall. While this later turns out not to be the case, it makes enough sense for Gwen to take to heart, especially when the theory is backed up by Harold who testifies that the obsession was apparent right around the time Trent first started to like her. However, Harold was also poorly informed, and only fueled to the fire.

The Aftermath: I
Trent explains to his audience during Total Drama Action Aftermath that one of the reasons for his failed relationship with Gwen was because Duncan and Gwen's budding friendship. Courtney, who was present on the set, shows vehement disapproval of this friendship. Although, unlike Trent, she seems angry with Duncan himself rather than Gwen. Trent also places full blame on Duncan for ruining his and Gwen's relationship, even if that was not Duncan's intention, as Trent explains that Duncan's reasoning for the number nine obsession was completely inaccurate and actually never had anything to do with Gwen, and therefore Duncan made Gwen panic over a nonexistent issue.

3:10 to Crazytown
Right after everyone (including Duncan) encouraged Gwen when she goes to jump onto the horse for the challenge, he said that they'll need a new captain. Gwen angrily said that she heard that while getting ready to jump.

The Chefshank Redemption
While most of the Screaming Gaffers are suspicious of Gwen's behavior (due to her guilt over the nature of Trent's elimination and subtly trying to throw the challenge for her team in this episode), Duncan is surprisingly one of the few who is not suspicious of her at all and stands up for her. At the end of the episode, Gwen is eliminated, but Duncan is one of the two, along with DJ, who did not vote her off. As she is handcuffed by Chef Hatchet and taken to the Lame-o-sine, Duncan stops them to offer himself in her place, as a way of saying that he really wants to be out of the competition (this may also be interpreted as his standing up for her and sacrificing himself for her), but quickly assures them that he was kidding as soon as Chef attempts to actually take Duncan instead. Gwen tells him that he won't get out of the competition that easily and wishes him good luck. Duncan smiles while he watches her leave.

One Flu Over the Cuckoos
When the team is talking about the side-deal Gwen had with the Killer Grips, Duncan said he still couldn't believe it and he "didn't know she had it in her," appearing to be more amused and/or impressed by her actions rather than embittered and/or betrayed.

The Aftermath: II
Gwen and Duncan's relationship was one of the major topics in this episode when Gwen appeared as a guest speaker. When Geoff told Gwen that her former teammates may not like her anymore, Gwen points out that Duncan didn't vote her off. Geoff and Bridgette showed a never-before-seen clip of Gwen and Duncan stargazing. After Gwen made fun of Duncan for openly gushing over Courtney, Duncan compensated with friendly roughhousing, which resulted in Duncan accidentally knocking Gwen to the ground, with Duncan soon landing on top of her and he said 'ooh' in a way that may have meant he liked it or that he had won. The two laugh, but then awkwardly pause and stare at each other as the video is paused and no further footage is shown. It is noted by Geoff that their lips were in very close proximity at the time, as if they were about to kiss at any moment. She then says that nothing happened afterward, and that they picked themselves up, stole everyone's underwear and strung it up the flagpole together. This infuriated Courtney, but Gwen insisted that nothing happened and that she and Duncan are still just friends. It is worth something that the anvil did not fall on Gwen after saying this, and it wasn't simply forgotten as Geoff brought the anvil to the audience's attention.

One Million Bucks, B.C.
Duncan and Gwen's friendship has been brought up again when the recently returned Courtney accused Duncan twice of cheating on her for Gwen during the prehistoric challenge. Duncan said his relationships are none of her business. Later in a confessional, Duncan truthfully says that he and Gwen are just friends, saying that Courtney "drives him crazy" in a frustrated tone, and then that she "drives him craaaazy" in a dreamy romantic tone.

Million Dollar Babies
Right before battling Courtney in the ball pit, Duncan said in the confessional that he knows or feels sorry about what happened to Trent and Gwen, calling it ugly. While in the ball pit, Courtney pins Duncan down. Duncan needs to make himself not throw any challenges for Courtney so he repeats "Trent and Gwen...Trent and Gwen...", not wanting his relationship with Courtney to end, like what happened to Trent and Gwen.

Mutiny on the Soundstage
Duncan reveals that he knows many things about Gwen, including her favorite band, what kind of car she wants, and what kind of guitar her brother has, knowing some details about her except what was required. Gwen's pet lizards' name is the question Duncan didn't know.

The Aftermath: IV
Gwen asks both Duncan and Beth a question on what they would do to help the environment. Duncan says he'd give it to Green Peace. Gwen is impressed with his answer. She also most likely voted for him to win.

Celebrity Manhunt's Total Drama Action Reunion Special
At the beginning of this special it showed that Duncan and Courtney broke up at the beginning of the episode and they didn't want to even look at each other on the red carpet. During the blogging between Heather and Gwen, Heather made a comment dressed in a Gwen wig saying "I wish Duncan was here so I could kiss him, even though I'm too scared to tell him I love him because I'm too cool." She also later said Gwen was sticking up for her boyfriend showing that Heather is one of the many people who think Duncan and Gwen are together. Meanwhile during her blog Gwen is getting tons of letters and emails asking if she liked Duncan, that they would make a great couple, and also that Courtney didn't deserve him. Gwen denies it and says that he has a girlfriend not knowing that Duncan and Courtney broke up. Then the two hosts of Celebrity Manhunt show her blog after she found out about the break-up. Gwen commented that she couldn't believe that Courtney let a guy like Duncan go. She then said that he was the greatest thing that ever happened to Courtney and said he was totally hot. Then nervously said that he was for perfect and hot for Courtney, saying that Courtney wasn't paying attention to how much she and him like each other... this may prove that Gwen is a little attracted to Duncan. Later in the confessional Courtney says that she'll have to keep a close eye on Gwen in season three, and called her a "boyfriend stealer."

Theme Song
In the theme song, Duncan and Courtney are seen together on a boat, and their paddles are then eaten by crocodiles. When the screen goes back to them, Duncan finds out that he had crashed into Gwen standing in an inflatable raft. Duncan is smiling at Gwen before he realizes she is sinking. While she starts to sink into the water, she looks up at Duncan sadly. Duncan, with a concerned look on his face, immediately leans over to help pull her out of the water, only to stop when he realizes that Courtney is glaring at him from behind. In the section where everyone makes a pyramid, they are seen next to each other.

Walk Like An Egyptian - Part 1
When they walk off the bus, Gwen makes a snide remark about Heather's "pony hair" hair extensions, which causes Heather to snap back at Gwen that her extensions are made from human hair. Duncan then retaliates that "you learn something new every day", and Gwen laughs. Gwen looks at him with a friendly smile, and he smirks back flirtatiously (which Courtney does not approve of). Gwen and Duncan were the only contestants that didn't want to sing during Come Fly With Us, until they were convinced by Chris' rules that unless they wanted to be instantly disqualified, all contestants MUST sing in each show. During the pyramid climbing challenge, Duncan suggested that Gwen could use a hand on climbing over the pyramid, something that Courtney wasn't very happy about but conceded to because, as she put it, "a three-person belay is better than a two-person one". While climbing the pyramid, Duncan is annoyed by both Courtney and Gwen, mainly because of their constant bickering. Later, when Chris rings the bell, Duncan is angry, saying that he was tired of listening to Gwen and Courtney's fighting and, after refusing to sing, quits, much to Courtney and Gwen's discontent. In a close up, Gwen looked shocked and sad about Duncan's decision.

Walk Like An Egyptian - Part 2
At the beginning of the episode, Gwen says that she still couldn't believe that Duncan quit the competition and showed some sorrow for his elimination.

Newf Kids on the Rock
In the confessional, Gwen states that being in a relationship with Duncan last season caused her to lose focus. She realizes her slip-up, corrects herself as meaning Trent, but then demands the confessional tape. Later during the episode she, along with Courtney, mistake a formation of rocks for Duncan, which Sierra claims only happens if you really really like someone. Courtney says she does, but Gwen denies this in a very nervous way, as if she was lying. This causes her team to lose the boat race.

I See London...


Gwen and Courtney capture Duncan against his will, at a punk rock club. When he is first let out of the bag, he doesn't even acknowledge Gwen or Courtney and is angry that they brought him back onto the plane.

Later in the episode, after trying to capture "Jack the Ripper," Gwen and Courtney walk into a punk club, where they see Duncan and capture him. When they bring him to Chris, Gwen apologizes to him for bringing him back on the plane. After Duncan returns to the competition, he begins hugging Courtney, but smiles romantically at Gwen as he says "Every time I ran from the cops, I thought of you." Gwen knows that the comment was directed at her, but walks away uncomfortably. Later, in the confessional, Gwen tells the audience that she is still confused and "fuzzy" about her feelings towards Duncan and his return. Suddenly, Duncan walks in on Gwen's confessional. Gwen is shocked that she didn't lock the door, but Duncan states that the lock was busted anyway. They then talk a little bit about Gwen's burn hand, and how Gwen is "so glad" Duncan was there to mock her about it. Duncan comes closer, grabbing her hand, and responds that he is too. She then smiles a bit and says "Hey." After a moment of silence, Duncan pulls Gwen in and they end up kissing. Tyler randomly comes in with an astonished look on his face and quickly leaves, shocked at the moment. Afterward, Chris mentions the kiss "as a great way to start a drama" while a freeze frame of them kissing is still displayed on a small TV in the cockpit.

Greece's Pieces
Gwen admits in the confessional that she liked kissing Duncan and would do it again. In the cafeteria, Duncan and Gwen stare flirtatiously at each other, which makes Courtney concerned. When Courtney notices they were staring at each other she pulled Gwen aside to find out why she was staring at Duncan. Gwen's replied by saying: "You've really got to do something about that Mohawk" which she really did not mean. Courtney believes this and talks to Gwen about what love does to you. While Courtney remains oblivious, Sierra states in the confessional that "Gwen has had a crush on Duncan since season one, and that Duncan has always had some feelings for her too". She also mentioned that there is a whole fanbase dedicated to "Gwuncan". During the song Duncan sings, he claims that he doesn't regret kissing Gwen. Gwen also sings with Duncan, despite the fact that Chris excused her from it. Eventually, Tyler admits that he saw them kissing and it upsets Courtney greatly. In the end, Courtney cries hysterically because Duncan had kissed another girl, while Gwen is worried that Duncan will get voted off. She sneaks into the elimination room to see who goes home. Duncan is supposed to go home, but Chris has an intern take the Drop of Shame instead, to the relief and happiness of Gwen.

The Ex-Files
Courtney is still mad at Gwen for kissing Duncan, and she attempts to lose to vote off Gwen and make Duncan jealous by flirting with Tyler. She also kicks Duncan and throws food on him to solidify their break up. While being stuck on the plane, Duncan openly flirts with Gwen. Later the Amazons are forced to sing and at the beginning of Boyfriend Kisser there was a drawing of her and her soon to be boyfriend, Duncan. Later on in the warehouse when they run into each other, Gwen and Duncan talk about the kiss they shared. She begins to talk about how their kiss was awesome, then adding that she knows about Courtney's flirting with Tyler getting to him and Gwen asks if he's changing his mind. Then, Duncan cuts her off and kisses her with his lips overlapping her's and popping his leg up romantically. He was showing that he still has feelings for Gwen despite Courtney's wrath. She tries to remain on her train of thought and tells him, "Why don't we just let things happen." They both decide to have a normal boyfriend-girlfriend relationship with no plans, pressure or mushy nicknames such as "pookums." Duncan agrees saying that's the reason why he likes her. When Duncan tries to run back to the challenge Gwen trips him (in a nice way) and says try not to be eliminated and Duncan answers back "Same to you" and stares at Gwen in a dreamy way. Gwen yet again sneaks in to the elimination ceremony when Team Chris Is Really Really Really Really Hot loses yet again to see who goes home. When Chris announces Tyler is going home instead of Duncan, Courtney storms in angrily and kicks Tyler out of the plane while telling everyone that she will have her revenge on Gwen and Duncan.

Picnic at Hanging Dork
Duncan pretends to be hurt by Courtney flirting with Alejandro (Duncan and Alejandro originally planed to trick Courtney to mess with her). Heather, suspecting the guys' plans, starts being nice to Duncan, making Gwen jealous and begin to lose trust in him, believing that he was playing her, too. Later, Gwen is relieved after Heather assures her that she's not trying anything with Duncan as she asks her for an alliance against Courtney. After seeing Duncan crying over Courtney (in reality, Duncan was, once again, pretending), Gwen fell for it too and tried to calm her insecurities with Cody, only to have his help during the elimination (but with no success). Duncan, in total contrast of Gwen, was not seen anywhere near Team Amazon's elimination ceremony in concern for Gwen. Because of Duncan's fake crying, Gwen left the competition partially on bad terms with Duncan, meaning Duncan would have to continue on without her.

Picnic at Hanging Dork
During the sheep shearing challenge, Gwen sees Duncan fake-crying over Courtney. Gwen angrily talks to herself, thinking he still has feelings for Courtney. Gwen, however, was seen at the ceremony every time she believed Duncan was in jeopardy.



Sweden Sour
Despite Gwen's elimination in the previous episode, Duncan seemed to show very little signs of remorse over her elimination. Upon landing in Sweden, Courtney angrily asks Duncan to apologize for cheating on her with Gwen, to which Duncan calmly replies back "Who?", to further irritate Courtney.

At the end of the episode, however, Duncan carved Gwen's face into a chair with his pocket knife, showing that he misses her.

Niagara Brawls
When Cody raises the possibility of Gwen re-entering the competition, Duncan approves the idea by smiling widely and saying "That wouldn't suck." It turns out that Blaineley was the one who was joining the show, much to Duncan's disappointment.

African Lying Safari
In this episode Heather mentioned to Duncan that he caused Gwen's elimination in an attempt to get him off his game, which worked. Duncan glared at Heather and then got tripped by Alejandro.

Hawaiian Style
They are seen sitting with each other in the beginning of the episode. When the ex-contestants were frightened by the bear, Duncan was holding Gwen. Other than that, there was hardly any interaction between the two, and Gwen was seen next to Trent more than Duncan.
