Ethan is the king of making bad choices. He's torn between his wife and his college roommate/business partner, and he won't make a bold-enough choice to keep either happy. In episode six, he becomes obsessed with the idea that Cameron and Harper have slept together. The episode features a lot of long, slow shots of him swimming underwater, which seemed to hearken back to the drowned body from the first episode. But despite a fistfight with Cameron in the ocean, Ethan makes it out of the week alive. At the airport, his relationship with Harper seems strong — helped by what seems to be his own tryst with Daphne.
