Diem admits to having a crush on Derrick, but she tries to ignore it because she needs to keep her head in the game. Tina is feeling sick, but Kenny tells her that the mission won't wait for her. And it won't--the message comes that they need to be ready by 5am. The next morning, they are informed of their challenge--Deep Blue. Four nautical miles off the coast of Australia, the teams have to dive 30 feet into the ocean to capture their team flag and hold their breath for as long as possible.

Later that evening, to Wes's excitement, Derrick decides to align with Wes. Wes has been angling to become allies with the strongest team, to no avail--until now.
