Total Drama Revenge of the Island (2012)

The two teams are sent into the the woods on a scavenger hunt, where one camper's alternate personality hooks up with someone else, despite their true self being in love with a different camper. Meanwhile, someone continues to sabotage their team's chances, but fails in the end due to someone else persisting towards a victory. The losing team attends their first elimination ceremony, where someone volunteers for elimination, but ends up on the winner team, while an intern is eliminated again.
