"Watery Grave" -- Life in the house takes its toll on the contestants and, after a night of partying, Melisande and Jared end up in the same bed. During the Net Zero Challenge, which requires the contestants to swim through an underwater maze while blindfolded and holding their breath, Melisande and Mae have to face their worst nightmare. While the guys suffer the humiliation of a body shave and make-up, the girls select bathing suits with stylist Brenda Cooper. Tempers flare at dinner when Jared is confronted by Jeanne and Sean about his attitude. As the contestants divide into two teams for their screen test scene, "Watery Grave," the audience will be surprised to learn who can keep their heads above water and who will be going home.
