Shawn selects Ella, Jasmine, Dave, Beardo, Rodney, and Samey; while Sky selects Leonard, Sugar, Amy, Topher, Max, and Scarlett.
Chris finally allows Ella to sing for real without getting annoyed by her personality, since he allowed singing on Total Drama World Tour. Sky potentially tells her that he has a boyfriend and Dave completely understands. So, Dave will be with Ella as a relationship and hug each other, which is so sweet. But Sky doesn't feel completely jealous about it. Dave doesn't act peculiar or nervous when Ella has her angelic persona and singing voice.
Max and Scarlett weren't pleased to see each other again. So, they were with their other friends. Scarlett is with Amy and Max is with Topher.
Ella is really relieved that Dave clearly likes her for real and made her heart glow even more. Dave and Ella are more focused on helping Shawn win the million, and not let the annoying/bratty Sky win, since brattiness won't get you anything in reality.
Meanwhile, Amy and Sugar were fighting each other who is going to help Sky the most to win. But Topher and Leonard will do it.
Rodney and Jasmine do very well on Shawn's side. Sky cheats for no reason, whatsoever, while Shawn tries to win fair and square. Eventually, Shawn won and he split the money with Jasmine.
Everyone and Christ are in a helicopter leaving the island for good, and Christ says that he will fix things up by being a good person, who cares about the people's safety instead of sadism.
Post-credit scene: Ella and Dave start kissing and feel great about it.
