Gwen and Heather

The Gwen-Heather Conflict is the major conflict between Gwen and Heather. This conflict is ongoing, and is arguably the most heated conflict in the series.

Overview
From the very moment they met, Gwen and Heather displayed a strong dislike for each other. To Heather, Gwen is a loser with poor fashion taste and a belligerent attitude. To Gwen, Heather is an annoying prima donna who will never stop to get what she wants.

In Total Drama Island, Gwen was one of the most frequent victims of Heather's cruelty. The most notorious example of this 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 gets her revenge on Heather, often with the aid of her friend LeShawna. 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; getting her head shaved bald. Heather was eliminated from the competition in the process, and Gwen advanced to the final two.

Their conflict continued in Total Drama Action, where they were placed on the same team, again. They immediately butted heads from the moment they stepped off the bus that carried them to their new location; an abandoned film lot. Although Gwen still despised Heather due to her actions in the first season, she reluctantly selected Heather for her team, the Screaming Gaffers, due to LeShawna's advice to "keep your enemies close." After Gwen was eliminated in The Chefshank Redemption, Heather added salt to Gwen's wounds by loudly boasting about outlasting her immediately afterward. 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 well alive.

The conflict has continued as of Total Drama World Tour, but is not too focused on. However, Gwen now has Courtney on her side against Heather, and together, the two girls team up against Heather and attempt to vote her off. So far, this plan still has not yet worked, due to Heather being spared from a fake elimination.

Due to Heather and LeShawna seemingly becoming friends, this is currently the biggest conflict in the Total Drama series amongst the female cast members (and possibly amongst all the cast members, against the Duncan-Harold Conflict in magnitude).

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

Not So Happy Campers - Part 2
While not as prominent as the beginning of Heather and LeShawna's rivalry, Gwen fully agreed with LeShawna that Heather's refusal to dive off the cliff in their first challenge was ridiculous.

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

Dodgebrawl
Heather and Gwen did not directly feud in this episode (Gwen was mostly too exhausted from the previous episode's challenge), but Heather allowed Gwen to get hit in the face with oatmeal fired by Courtney (who meant to hit Heather).

Not Quite Famous
The first major step of their rivalry originated in this episode. The challenge was a talent show and Heather declared herself team captain, much to Gwen's dismay who left with Trent to go to the Dock of Shame to get away from Heather and everyone else. Heather feeling threatened by her independence, becoming suspicious, found Gwen's diary and read it out for everyone to hear at the talent show, revealing her crush on Trent. Later, Gwen got revenge by dumping Harold's red ant farm on Heather (while sleeping), who ran out screaming. Gwen smiled and went to bed peacefully that night.

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 teammates.

Paintball Deer Hunter
Heather tells Gwen to "worry about her own fluffy tail" grumpily.

If You Can't Take The Heat...
Gwen (along with Lindsay) could barely contain her laughter when Heather accidentally blew up her flambe, which not only burned Heather's face, but completely burned away her eyebrows. Gwen was not active in tricking Heather into running into the freezer and locking her in, but she most likely got a kick out of it, since she showed 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 (an 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 now 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 get Bridgette in her alliance. Gwen told Bridgette to watch out for Heather, and the two exchanged looks while Bridgette, sheepishly, walked away. After arguing, Heather divided the cabin; one side being Lindsay and Heather's, the other being LeShawna and Gwen's. Bridgette ultimately chose 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 Heather 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 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 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, and next time she won't be so lucky.

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 when she heard screaming (which was actually DJ's); 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 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 finally got 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 fast-acting cupcake (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 was laughing at the back of Heather's head, which had a smiley face on it drawn by LeShawna, refused to team up with her and laughed when she was being attacked by beavers.

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 by, 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 puts 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 after crosses the line when she takes a picture of Duncan and tells the viewing world how badly she wished Duncan was here so she could kiss him, "I wish Duncan was here so I could kiss him, even though I'm too scared to tell him how much I love him." 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 (Gwen) boyfriend. Oh wait! Duncan's your (Courtney) boyfriend. My mistake!"

Walk Like An Egyptian - Part 1
Early in the episode, Gwen bumps into Heather's backpack. Gwen then says that on the plane she'd like any seat, but one behind Heather's "pony hair ponytail". The two were later placed on Team Amazon.

Broadway, Baby!
Gwen says to Courtney that she'll help her vote off Heather when the time comes.

Slap Slap Revolution
During Eine Kleine Gwen sings about how happy she'll be when Heather "gets voted off for being such a lout" and she smiles when Courtney teases Heather by saying she'll "dance a jig when Chris throws her off the plane" and poking her nose. 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.

Newf Kids on the Block
When Heather was climbing into the vents to reach the loser's class cabin withought being noticed, Gwen oddly asked what she was doing and points that unless Heather turned into Izzy and is chasing elf, that what Heather really wants is related to Alejandro.

Episodes Against
Despite their heated conflict, there have been a few instances in which Gwen and Heather actually seem to get along, or just don't mind each other.

The Big Sleep
When Gwen asks Chris about the challenge being too much, Heather agrees with her, although she calls her 'weird goth girl'.

Dodgebrawl
When Noah criticized the lack of effort the team put in the challenge they just lost, Heather announced that for once agreed with Gwen in wanting Noah to shut up, since he didn't even try to help the team out.

Paintball Deer Hunter
Gwen and Heather were both deers, and when told they had to dress up like them, they both thought it was unfair. They also both disagreed with Cody when he said the challenge might be fun.

Hook, Line, and Screamer
Heather shows concern when Gwen is confronted by the real escaped psycho killer with a chain saw and a hook. Gwen also runs into the washroom, concerned for Heather's well being, saying "Are you okay?" Later on, when Gwen is unknowingly facing the real psycho killer, Heather and the others rush over to her to let her know what she is truly up against. This could mean that although the two dislike each other, they do not want each other to die.

Wawanakwa Gone Wild!
After Gwen captured her assigned animal and returned it back to camp, she told Heather to open the cage door, in which Heather listened and opened it for her, making Gwen win the reward for completing the challenge first. However, Heather doesn't seem to mind Gwen winning the challenge, or she just doesn't care.

Are We There Yeti?
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 was the end of the series as it had originally been, it is possible that it was implied that Gwen and Heather were on good terms.

Riot On Set
Although it was a strategy designed by LeShawna, Gwen picked Heather to be on her team in Total Drama Action.

The Chefshank Redemption
Gwen compliments Heather by saying that she's the skinniest of all the girls, in order to convince Heather to try to get out of the top of the trailer, in order to free the rest of them. Heather tells Gwen she agrees with her, and agrees to exit from the hatch, much to Gwen's pleasure.

Walk Like An Egyptian - Part 2
When Courtney tells the camel to hurry up in a polite way, Heather corrects her on how to talk to a camel, screaming at it and telling it to "freakin' move it!" Gwen chuckles at Heather's comment and sarcastically tells her that her way of communicating with the camels is "much better".

Super Happy Crazy Fun Time Japan
While Team Amazon starts arguing about who does the pinball challenge, Heather says Gwen's face could use some remodeling, but Gwen quickly reminds her that they're on the same team and that she has to flip the "witch switch" back to off, hinting that Gwen may have believed that Heather was not completely "witch-like" at one point in time.
