Later, Chelsea and Christina are walking to get tree mail, and Chelsea promises to take Christina with her on reward. Chelsea later wins the reward challenge. When asked who she wants to go with, she picks Sabrina and Kim.

On the boat, Chelsea, Sabrina, and Kim enjoy the reward, and team up to go to the final three. Back at camp, Alicia, Christina, and Tarzan are irritated by Chelsea's choice to take Kim on reward despite the fact that Kim went on the last three rewards. The three decide to vote Chelsea out. Tarzan then tells Alicia to take Sabrina and Christina to the final three. When the rewarded trio returns to camp, they immediately witness a brief argument between Tarzan and Alicia.
