Harold- Trent told Harold to quit the game, stating that it's his own fault for Team Victory's loss.
Bridgette and Geoff- Trent seduced Bridgette and left her stuck to a pole.
Leshawna and Heather- Told Leshawna to seize the day, by slapping Heather across the face. In TDAS, Trent eliminated Heather unjustly, by using the immunity idol she found and eliminating her with HIS sole vote. Trent admits that he did that, as retribution for how Heather eliminated him in Season 1, when she kissed him in front of Gwen.
DJ- Sabotaged DJ's run in the bobsledding challenge.
Noah- While Trent didn't get Noah eliminated, he had to vote for Noah, under Duncan's orders.
Tyler- Joining Duncan in eliminating Tyler.
Duncan, Courtney, and Gwen- Trent told Tyler to reveal Duncan and Gwen's kiss. As a result, Courtney told Team Amazon to eliminate Gwen. This succeeded, because the swing vote, Cody, voted for Sierra. Heather and Gwen voted Courtney, while Courtney and Sierra eliminated Gwen. In China, Courtney helped Trent eat his food. Heather noticed this and disqualified Trent from the challenge.
Owen- Told the other contestants to vote off Owen.
Cody- In the last episode, Trent knocked Cody out, giving him 3rd place.
