Gwen's feud with Heather continue after Total Drama Action has ended. She also hosted a web show talking about her time on Total Drama in addition of spreading the need to protect the environment. During one of her segments, she brought Katie and Sadie as her assistants to substitute Leshawna who was participating on a different reality show at the time with Tyler. However, the two of them were more of an annoyance instead of being helpful. The show soon came under attack by Heather, who mocks the show with her own web video.

In Aftermath Aftermayhem, Gwen is one of the three guests added to the peanut gallery, the other guests being Noah and Tyler. Blaineley introduced her as the girl referred to as "boyfriend kisser," and the "new Heather." Unlike last season, she came into the studio with a smile on her face and wasn't booed by the audience. However, a bear follows her for an unknown reason, but was pulled back by the interns. Like Noah, Gwen doesn't seem to be excited about returning to the plane, but participate anyway due to their contract. While in line, she was reunited with Trent, who brings up about her and Duncan and says that he didn't see it coming (despite his jealousy from the previous season). Gwen did not receive one of the cans that allowed an attempt to return to the competition. After Tyler was eliminated, she talks and jokes around with Trent, showing she is still able to be friends with him.
Gwen's elimination leaves an impact to many of the remaining contestants and she was mentioned multiple times. While Sierra and Courtney are excited about her absence, both Duncan and Cody lamented her loss in Sweden Sour. The latter was so depressed that he is unable to help out in the challenge and ended up using all his team's materials to craft a giant wooden sculpture of Gwen's head. He even dreamed about marrying her at one point in his sleep. Duncan, despite claiming otherwise to Courtney, also shows that he misses her by crafting her face onto the side of his chair in the first class. When Chris announces that someone will be returning to the competition in Niagara Brawls, everyone at first believes that it would be Gwen, much to both her love interests' excitement, only to find out that the person is Blaineley. She was also mentioned by Heather in African Lying Safari in order to distract Duncan which subsequently leads to his elimination. Duncan was not disappointed being eliminated again and happily sends a message to Gwen that he will be seeing her soon in the exclusive clip.
In Hawaiian Style, Gwen was sitting in the Peanut Gallery next to Duncan. Like most contestants, she chose to support Cody. In a deleted clip, she and Duncan are seen relaxing together while Courtney was singing a song insulting them. Duncan eventually got so angry that he threw a sandal at Courtney's face, knocking her down. Gwen smiled at Duncan and they kissed. In Hawaiian Punch, upon seeing Cody being eliminated, Gwen switch sides and support Heather instead. After the challenge is over and the winner is declared, Gwen and the other contestants quickly escape the island, mocking Chris and Chef along the way after Ezekiel crashes into their boat.
In Bigger! Badder! Brutal-er!, Gwen appears on the yacht with the other twenty-three original contestants. She and Duncan are seen making out passionately while DJ, Harold, and Leshawna dance nearby.
Gwen appears in The Treasure Island of Dr. McLean, once again facing her worst fear; being buried underground, but this time with the new contestant, Sam. When she realizes where she is, she begins to hyperventilate and bang on the chest. As part of the challenge, the new contestants are required to save the two of them. Gwen attempts to call Chris with her cellphone, saying he has gone too far, but she faints when Sam farts on her. Eventually, Jo found the chest they are in and Dakota frees them, but she just tosses Gwen aside in order to save her beloved, Sam.
Gwen returns to All-Stars for the sole purpose of trying to resolve her friendship with Courtney, but Courtney is not willing to forgive this transgression and continues her hatred towards her from their last encounter. Compared to Total Drama World Tour, she seems to lament the kiss she had with Duncan more than ever, especially when she is placed on the Villainous Vultures solely for her involvement in the love triangle. Because of the contrast she has with most of her team, during the challenges, she would try to make her team work together, but since she was the only one to place any trust in anyone on her team, this often goes nowhere. Several contestants on the team, including Heather, Jo, and Alejandro sometimes try to fake their refusal to work together in order to form an alliance with her, but Gwen doesn't fall for it because she knows what they are up to. In addition, due to a running gag where Gwen would accidentally hurt Courtney in the first few episodes when she is attempting to apologize to her, Chris and the rest of her team think she is actually a villain.
When the season begins, her and Duncan are still in a relationship, although there appear to be some issues regarding it, mostly due to the aforementioned regret from Gwen. Duncan is shown to be the only one who reassures her when she is placed on the Villainous Vultures, but this fails to cheer Gwen up. Though Duncan is among the contestants that think that Gwen is trying to actually be a villain, he still shows commitment to her, such as when he sacrifices himself to get shot by a leech in Saving Private Leechball, which later causes him to be involved with a team switch with Courtney. The two do not interact again until Moon Madness, but the episode also marks the end of their relationship. Frustrated by his mentions of Courtney during the episode, Gwen appears to be jealous and frustrated with him until, at the end of the episode where he mentions her again, she breaks up with him, saying that any thrill of the relationship was over. After their break up, Gwen's opinion on Duncan greatly changes as she frequently makes fun of him whenever he acts like a hero and even ignores him when he tries to warn her about Mal's existence.
Gwen continues to try to make up her friendship with Courtney once she switches teams, but similarly to when they were on different teams, Courtney still hates her greatly at first. Even after Gwen cries in the confessional over her failing to make up this friendship, she still does not believe that she is trying to actually be friends with her, and when Gwen saves Courtney from a deer that was about to attack her, she barely shows any appreciation towards it at all. It is not until No One Eggspects The Spanish Opposition, where after Gwen tells Courtney that she broke up with Duncan, where the two would start to be friends again, but the next episode has Chris rig the match in order for the two to fight each other. Even though the fight is initially fierce when Courtney is shown videos of Gwen kissing Duncan, this ultimately proves to be beneficial, as the two are able to vent out their frustrations and renew their friendship, allegedly for good. The events of the episode cause them to get along unusually well in You Regatta Be Kidding Me, as the two work together in the challenge even though Chris stated only one person could get immunity and they hope that the other wins the competition if they do not.
Gwen is able to get along with Cameron quickly after he switches teams. She is the only one who does not glare at him when he transfers onto the team and, while they work together during No One Eggspects The Spanish Opposition, their friendship is put under a strain when, in Zeek And Ye Shall Find, "Mike" tricks him into thinking that she couldn't be trusted. Despite her case of claustrophobia working against her during the challenge, she is still able to save Cameron's life after he falls down a hole into the water, working together and letting her eventually win individual invincibility for the first time since I Triple Dog Dare You! She and Zoey also become friends after Zoey helps her to calm down from her claustrophobia. Despite her making and keeping these two friendships, Courtney and her did not last until the end of the season. Although Gwen was upset to hear that Courtney (accidentally) kissed Cameron while dating Scott, due to all the flak she got from her when she did the same to Duncan, it escalated further in Sundae Muddy Sundae. Due to Courtney's aforementioned relationship with Scott, she intends to betray her once there were only three contestants left. After the chart she made outlining these eliminations was exposed by "Mike," Gwen refuses to work together with her and only wants to be friends with her if Courtney votes herself off that night. Whether she follows through with this promise or not is unknown, but even then, Gwen doesn't seem to miss her when she gets eliminated.
As the only veteran left in the final four, Gwen is happy to have accomplished this feat, but she is also left without any allies in The Bold and the Booty-ful. She also fails to get Scott allied with her due to his perception that it was her fault that him and Courtney were done for good. She is tasked to find a painting of Chris in his cottage, but her progress is slowed down substantially by "Mike" and the painting she finds she finds has a smear on it, causing her to use bear feces in order to get the correct shade of brown. This disgusts Chris and causes her to get disqualified, but she returns for the finale as one of Zoey's helpers. While she helped Zoey get across the first moat, Mal throws her off of the second moat in order to not let her help Zoey any further. While she isn't of any help to Zoey later on, she does at least manage to hit Heather in the head with a stick, which is something she had been wanting to do for four seasons and give Cameron a friendly kiss on the cheek. She is last seen floating away on one of the cabins with Mike, Zoey, and Cameron, telling Mike she never wants to participate in Total Drama again.
