Doug and Carrie are returning home from a trip, and when their plane makes an unexpectedly rough landing, the oxygen masks fall from the ceiling. Even though they are safely on the ground, Doug panicks and grabs the only available mask for himself and doesn't give Carrie a second thought. Carrie's feelings are hurt that he didn't think of helping her first, while Doug doesn't see how what he did was wrong. When Carrie says that she will forever view Doug differently because of the incident, only then does he feel guilty. He sets out to prove to her that if her life were actually in danger, he would without question, save her.
Meanwhile, Spence is looking for a new place to live. He ends up moving in with Danny Heffernan after things with the hot Brazilian exchange student don't go as he'd hoped.
