Gwen and Heather

This article focuses on the interactions between Gwen and Heather.

Overview
From the moment they first met, Gwen and Heather displayed a strong dislike for one another. In Total Drama Island, Gwen was one of the most frequent victims of Heather's cruel tricks, and was given the nickname "Weird Goth Girl." The most notorious example of this bullying was in Search and Do Not Destroy, where Heather deceives Gwen into believing that her love interest, Trent, was cheating on her with Heather. However, Gwen usually exacts her revenge on Heather, occasionally with the aid of her friend, Leshawna, who has a similar hatred towards Heather. It was due to Gwen orchestrating a brief alliance with Owen in I Triple Dog Dare You! that Heather suffered her greatest humiliation to date: accidentally having her hair shaved off. Heather was eliminated from the competition in the process and Gwen advanced to the final two with Owen for the $100,000.

Their intense rivalry and conflict continues in Total Drama Action, when they are placed on the same team again. They immediately butt heads from the moment they step off the bus that carry them to their new location, an abandoned film lot. Although Gwen still despises Heather due to her actions in the first season, she reluctantly selects Heather for her team, the Screaming Gaffers, due to Leshawna's advice to "keep your friends close, and keep your enemies closer." Following the conclusion of the second season, it was revealed in Celebrity Manhunt's Total Drama Action Reunion Special that the two girls engaged in a video blog war with each other, confirming that the conflict is still very much alive.

The conflict has continued as of Total Drama World Tour, but has lost some focus. However, early on in the season, Gwen and Courtney teamed up against Heather, and attempted to vote her off. The plan ultimately failed, due to Heather being spared in a fake elimination. Later, Gwen is caught kissing Courtney's boyfriend Duncan behind her back, as revealed by Tyler; this scandal completely took the target off Heather's back as Courtney furiously turned against Gwen and desperately tried to get her eliminated. Although Heather teamed up with Courtney for a while against Gwen, she eventually lost her patience with Courtney due to her going so far as to throw challenges to get their team to lose so that Gwen could be voted off. Since Heather disapproved of this, considering winning more important than eliminating Gwen, she ironically ended up teaming up with Gwen against Courtney, only for Gwen to be eliminated in the same episode that they teamed up in.

Not So Happy Campers - Part 1
Sparks of the conflict begin in this episode as the Screaming Gophers first walk into their cabins. After Gwen makes a sarcastic remark at Heather for her whining about the cabin, the latter retorts by giving her the nickname of "Weird Goth Girl," which she goes on to use in reference to Gwen throughout the series.

Not So Happy Campers - Part 2
Gwen fully agrees with Leshawna that Heather's refusal to jump off the cliff during their first challenge is ridiculous.

The Big Sleep
Gwen glares at Heather after she calls her "Weird Goth Girl".

Dodgebrawl
Heather and Gwen do not directly feud in this episode (Gwen is mostly too exhausted from the previous episode's challenge to care), but in the Mess Hall, Heather allows Gwen to get hit in the face with oatmeal that is fired by Courtney (who was trying to hit Heather) and does not care that someone else got hit.

Not Quite Famous
The challenge for this episode is a talent show and Heather declares herself team captain, much to Gwen's dismay; Gwen then leaves with Trent to go to the Dock of Shame, to get away from Heather and everyone else. Heather, feeling threatened by her independence and becoming suspicious, finds Gwen's diary and read it out for everyone to hear at the talent show, revealing her crush on Trent. Later, Gwen gets revenge by dumping Harold's red ant farm on Heather (when she is asleep), who runs out of her cabin screaming. Gwen smiles and goes to bed peacefully that night, while Heather screams outside.

The Sucky Outdoors
Heather tells the rest of the team that Gwen for sure would be the next one to leave the island after what Gwen did to her the night before. Trent points out that Gwen's retaliation was justified, considering how severely she humiliated Gwen on national television. Heather refuses to admit that she did anything wrong and swears that Gwen is going down.

Later that night when the bear attacks the Gophers' campsite, Lindsay remarks that it probably ate Izzy, to which Heather remarks that at least it won't be hungry for them. Gwen is noticeably shocked at Heather's lack of concern for her fellow teammate.

Paintball Deer Hunter
Heather tells Gwen to "worry about her own fluffy tail" grumpily during the challenge when Gwen asks Heather if she is going with Trent and herself in the challenge.

If You Can't Take The Heat...
Gwen can barely contain her laughter when Heather accidentally blows up her flambé, which not only burns Heather's face, but completely burns away her eyebrows. Gwen was not active in tricking Heather into running into the freezer and locking her in, but she most likely gets a kick out of it, since she shows no concern whatsoever about Heather being locked in the frigid freezer.

Who Can You Trust?
Gwen and Leshawna mocked Heather that morning, who was suffering from a cold after being locked in a freezer for so long in the previous episode. Heather vowed to get her revenge on Gwen (who, actually, had nothing to do with it). Luckily for Heather, she and Gwen were partnered up for the first challenge, in which Gwen was to climb to the top of a mountain that had explosive dynamite and other various obstacles, while Heather had to hold the rope to keep her from falling. Gwen asked Chris if they can trade partners because she refused to trust Heather. Heather dropped Gwen on her head (by accident), and later revealed her underwear to the world (on purpose). Later, after Heather fell into the jellyfish pool and was relentlessly stung and electrocuted, Gwen was seen very content with this incident in the confessional stall.

Brunch of Disgustingness
The teams were then dissolved into single-gender teams, and Bridgette, the only female Killer Bass member remaining, was the only new girl on her team. Heather began acting nice towards Bridgette, but to only convince Bridgette into joining her alliance. Gwen told Bridgette to watch out for Heather, and the two exchanged angry looks while Bridgette, sheepishly, walked away. After arguing, Heather divided the cabin; one side being Lindsay and Heather's and the other being Leshawna and Gwen's side. Bridgette ultimately chooses Gwen and Leshawna's side. Later on, during the competition, Heather was notorious for pressuring the other girls to eat the disgusting meals (especially vegetarian Bridgette, who struggled with eating meat-based dishes), only to hypocritically chicken out on a number of meals herself. At one point, Gwen grabbed Heather in an attempt to force her to practice what she preached. At the end of the episode, Gwen and Leshawna lock Heather and Lindsay out of their cabin.

No Pain, No Game
There were brief moments where Gwen was specifically glaring at Heather from afar in the very beginning of the episode.

Search and Do Not Destroy
Heather spotted Gwen kissing Trent after he helped her out with getting her key. Considering the romantic relationship in a rival alliance, Heather wanted a monopoly on all alliances and thus made a plan to break up Gwen and Trent. She had Lindsay forge a love note to Gwen that instructed her to meet him at the Dock of Shame at a specific time for a "surprise." Meanwhile, Heather lured Trent to the dock and proceeded to tell him several assorted lies about Gwen and how she "really" felt about him. Heather tricked Trent into thinking Gwen was only using him to get further in the competition, that she found him to be a cliché and that his music sucked. Just as Gwen arrived to the dock, she saw Heather suddenly kiss Trent. Without even being noticed by Trent, Gwen ran off to the other side of the island to cry out her sorrows in seeing her mortal enemy kiss the one guy she cared for in the competition. Heather succeeded in turning the two against each other, though after all of that, Gwen still did not vote Trent off.

However, after Gwen told Leshawna her side of the story, Leshawna recruited nearly every camper into a temporary alliance to get rid of Heather or Trent; preferably Heather. Gwen did not know about this. Since Heather won invincibility, the vast majority of the campers voted off Trent. After Heather told Trent he was wrong about getting along with everyone, Gwen accused her for not caring, Heather revealed her treacherous scheme moments before Trent left the island, allowing he and Gwen to make amends. While they parted on a positive note, the end result was ultimately what Heather hoped for: making Gwen vulnerable by getting rid of her boyfriend.

Hide and Be Sneaky
Gwen is still depressed over what Heather did in the previous episode, but Leshawna promises they will get revenge on her. Later, while Gwen is taking a shower, Heather turns the hot water on in the sink and gives Gwen a freezing cold shower, simply to get on her case. She then gives Gwen a fake apology for the stunt, which prompts Leshawna to retaliate by physically attacking Heather. Shortly after Gwen is found by Chef Hatchet (in her grass camouflage), Heather announces that she has won invincibility again by finding Owen and DJ. Heather passes by Gwen, mocking her for how she looks in her camouflage outfit. Later on, Heather tries to get the girls to unanimously vote one of the guys off, as she became aware of their alliance and their plot to pick the girls off, one by one. However, Gwen and a few choice others refuse to agree on Heather's choice, making the plan to vote unanimously fail.

That's Off the Chain!
When a bird excreted on Heather's head, Gwen is satisfied and laughs, considering that it is just another way of karma getting back at Heather. When Heather said that her bike weighed only two ounces, Gwen remarked "just like her brain.” Gwen also looked mad when Heather won the motocross challenge. Gwen later glared at Heather for using Lindsay to thrust her way through the competition, and was very pleased to see Lindsay curse Heather out after she got Lindsay eliminated. It's also worth noting that this one act gave Gwen new respect for Lindsay, who she had a tense friendship with. Prior to this, Heather reminds everyone that she gained invincibility for the third time, and that no one can touch her; with a vengeful expression, Gwen points out that it was only for this particular week.

Hook, Line, and Screamer
Heather mocks Gwen and Duncan for their love of horror movies, finding it to be only mindless guts and gore. The two argue that it is actually filled with psychological trauma, using the terrified DJ as an example. Heather is the first one to ignore Gwen's lead on the situation of the challenge, which is to survive a real-life horror movie. Heather dismisses the challenge completely and heads off into the shower in spite of Gwen's warnings. This is one of the few episodes where Gwen shows a bit of actual concern for Heather's well-being (and vice-versa); first, when Gwen rushes into the bathroom after hearing what she thought was Heather screaming (it was actually DJ) Heather assures Gwen that she is fine. Before leaving, Gwen sarcastically notes that Heather's green facial mask is a good look for her, shocking her.

Wawanakwa Gone Wild!
The challenge was that the campers had to catch an animal that they randomly chose and could use anything in the boat house. Gwen had a duck and Heather had a bear, so they got in a tug-of-war fight over a net. Gwen then saw duck bait, so she let go of the net, causing Heather to fall and get stuck in a bucket of fish. Gwen taunted Heather as she was walking out, telling her that the net they were fighting over would never catch a bear anyway. When in the confessional, Heather spews that she's most likely the favorite to win the entire competition because of the remaining campers on the island. When naming off everyone who's left, she calls Gwen "Weird Goth Girl,” the usual nickname given to her by Heather. Later in the episode, Heather tells Duncan to scrub the shower with Gwen's toothbrush since Leshawna took many showers after falling in mud.

Camp Castaways
In the beginning of the episode, Heather and Gwen were sitting on the steps of their cabin when Heather begins taunting Gwen about Leshawna's elimination. Gwen then stomped on the stairs to mess up Heather polishing her toenails and told her to eliminate herself (Gwen: Why don't you put us out of our misery and vote yourself off). Later, they, Owen, and Duncan got stranded on a deserted island and Heather said in the confessional stall that she was with crazy people (referring to Gwen and Duncan). Gwen, trying to get back to the campsite, built a raft and started to sail away with Duncan, making Heather plead to go with them, but Gwen tauntingly dismissed her. When Owen convinces his three friends to confess their sins before they die on the island, Heather became suspicious of Gwen after having heard her story (which was unheard by the viewers), and even suspected that Gwen may not be her real name. Gwen became suspiciously uncomfortable at this last remark.

Are We There Yeti?
Gwen, Heather, Owen and Duncan all awoke in the forest, as the challenge was that they had to get back to the campsite, provided with equipment to help them (Chef Hatchet was in charge as Chris McLean was away). Gwen and Heather were teamed up, and Gwen said in the confessional stall that she couldn't believe that the producers left her in the woods with Heather. Heather then said she would instantly ditch Gwen, but would keep her around so if a bear came, she could push Gwen for the bear to eat her. They argued, but eventually decided to work together so that they could win invincibility. Throughout the challenge, they kept on outwitting the boys and vice-versa. They had lost all their equipment to the boys and when they were walking, they both insulted each other on how they both smell.

I Triple Dog Dare You!
Gwen and Heather were bad mouthing each other in the confessional stall. Afterward, they went to the challenge, which was that they had to play 'I Triple Dog Dare You.' Gwen dared Heather to lick Owen's armpit, then Heather dared Gwen to chew and eat her toenail, slowly. When Gwen asked Heather if she was satisfied, Heather responded gleefully saying, "Very. I'm just picturing Trent watching this, and something tells me he won't be eager to lock lips with you anytime soon." The Trent jokes continue after Gwen had to drink powdered fruit punch from the communal toilets. Heather taunted her by saying that Trent would never want to go near her: "At this rate, Trent's gonna need a fumigation squad just to-" Which Gwen, sick to her stomach, responded to by burping in her face, cutting the jesting short. This quieted Heather. Eventually, Gwen and Owen teamed up when Gwen asked him to give half of his freebies to her, and began whooping Heather with dares. After Heather was eliminated and had her head shaved, Gwen and Owen were relieved that they had finally gotten rid of Heather after everything she had done.

The Very Last Episode, Really!
Gwen did not list Heather as one of the five sane people, as she called her a backstabbing and manipulative jerk. Heather tampered with the obstacles in Gwen's course in efforts to make sure she lost. She greased her pole (wiped off by Trent), gave her a cupcake made with laxatives (eaten by Owen instead), and pulled Justin's shirt off (but it distracted Owen too). At the end, when the guys throw Chris into the water, Gwen asked Heather if she liked it. Heather first says no, but smiles and says yes. Gwen reminds Heather that she still stinks, however (Leshawna locked Heather in the confessional stall after Owen had used it when the cupcake he ate got through to him). In the alternate ending, Gwen invites every camper to her party except for Heather. Heather also scowled at Gwen's win.

Total Drama, Drama, Drama, Drama Island
Gwen is laughing at the back of Heather's head, which has a smiley face on it drawn by Leshawna, refuses to team up with her, and laughs when she is being attacked by beavers, and also laughed when Trent offered to help her.

Monster Cash
Though Heather has been humbled by losing her hair (being forced to wear an ugly wig or else go about bald), she and Gwen are still bitter enemies as they even fight while trying to disembark from the bus when they arrive to the new location of the competition. Gwen and the other girls hate Heather to the point where they are determined not to share a bunk bed with her.

Riot On Set
Following Leshawna's advice to keep her enemies close, Gwen reluctantly chose Heather to be a member of her team, the Screaming Gaffers (much to Heather's surprise).

The Chefshank Redemption
Gwen points out Heather's weaknesses, one of them being shameless flattery. When Heather questions Gwen on what Lindsay was saying to her, Gwen refuses to talk about it and flicks barf at Heather's head after she got covered with it when Lindsay threw up all over her face. Heather becomes suspicious of Gwen throughout this episode when Gwen fakes a cramp and when the Killer Grips mention Trent. When it was revealed that the Grips won, Heather calls Gwen a traitor. While eating, Gwen and Heather glare at each other and snap insults like death mask and smugness. Heather insulted Gwen when she was eliminated, saying that she lost, and was therefore a loser. She stated that Gwen's elimination meant that it was "the best day of her life." Gwen accepted her loss, but glared at Heather before leaving.

Celebrity Manhunt's Total Drama Action Reunion Special
Early in the episode, Gwen was shown making fun of Heather's weight gain, much to her dismay. In this episode Gwen and Heather have a blog war feud. When Gwen has a blog about saving the earth, Heather makes fun of this by impersonating Gwen while wearing a wig similar to Gwen's hairstyle and pokes fun at Katie and Sadie by using hand puppets. Heather soon crosses the line when she takes a picture of Duncan and says "I wish Duncan was here so I could kiss him, even though I'm too scared to tell him how much I love him" in order to further embarass her. Gwen sees this and says Heather was turned down by every guy in her school for a dance and shows footage of Heather's cat licking her after it cleaned itself. Then Josh interviews them and they exchange names and Gwen gets angry and attacks her, forcing Heather to the ground and beating her senselessly. Later in the episode after Gwen tells Courtney that Duncan should drive, Heather says to Courtney "She's just sticking up for her boyfriend. Oh wait! Duncan's your boyfriend. My mistake!"

Later on, Gwen supports Courtney when she scolds Heather for throwing away the meat grinder they had won in the previous episode when Courtney had told her it could come in handy. Later, after Leshawna attacked Heather and knocked her tooth out during the dance challenge, Gwen made fun of her in the confessional, saying she couldn't think of a better way for Heather to "take one for the team.”

The Am-AH-Zon Race
When Team Amazon was choosing which path to take in the jungle, Heather taunts Gwen saying that she should choose, as she had jinxed the team with her comment on good luck. She goes on saying that if Gwen chose the right path, she was a hero, and if she didn't, she'd be the next one eliminated. Gwen then says that Heather's parents must love the show, as it gets her out of the house, which Heather responds to by sticking out her tongue. When Team Amazon loses the challenge, Heather blames it on Gwen. At the elimination ceremony, Chris reveals votes, showing that Heather voted for Gwen, and that Gwen (along with Courtney and Sierra) voted for Heather. While voting, Gwen tells Chris that she'll give him ten bucks if he forgets to give Heather a parachute. After revealing the votes, Chris then says that the ceremony was a fake and there was no elimination, shocking Gwen (and Courtney, Cody and Sierra).

Newf Kids on the Rock

It is later revealed though that Heather crossed her fingers while in the dark room, lying intentionally to give Courtney confidence, but not trusting her actions due to her desperate attempt to throw the game instead of play fairly. After Gwen asks Duncan what happened to him after the kangaroo had thrown him out of its pouch and Heather asked Duncan if he was okay, Gwen and Heather glare at each other. Despite the conflict, Heather votes off Courtney both due to continued sabotage of challenges and her attraction towards Alejandro making her jealous of his "flirting" with Courtney.

She seemed very intent on making Gwen receive the last marshmallow over Izzy.

At the end of this episode, they manage to trick the boys by taking a page out of Heather's book by deceiving the boys into believing they were weak and helpless girls, and thus won the challenge, even high-fiving each other at the end.

The Very Last Episode, Really!
In the end of the episode, Gwen bumps Heather playfully and tells her she has to be a little happy to see Chris thrown into the water. They smile at each other and Heather admits she is happy. Gwen says she still stinks from when Leshawna threw Heather into the confessional earlier, though Gwen was smiling so she may have meant this playfully, or that she actually thought they could be on good terms, but not friends ("You still stink, though"). Heather seems upset to hear that from Gwen, possibly feeling guilty. If this had been the end of the series as it had originally intended to be, it is possible that it was implied that Gwen and Heather were on good, or at least better, terms following the season's climax.

Picnic at Hanging Dork
In the beginning of the episode Heather appears in the first class cabin offering a cookie to Gwen, but before she could get it, Courtney took it and destroyed it.

Heather assures Gwen she isn't trying to steal Duncan from her, even before Gwen gets to actually ask her. After Heather confirms Courtney is throwing the challenge, Gwen asks for an alliance. Heather doesn't think twice and agrees to vote for Courtney, as she considers winning is more important than voting Gwen off.

 * This conflict is closely related to the conflict between Heather and Leshawna, due to Gwen and Leshawna sharing a close friendship.
 * Ironically, both girls are always placed onto the same team together.
 * Heather had kissed both of Gwen's boyfriends at one point in the series.
