Marmalard and other Omegas lure Otter to a motel and beat him up after Mandy's best friend Babs tells him that Mandy and Otter are having an affair (although this is actually an exaggeration since Mandy implied it to be just a one-night stand). The Deltas' midterm grades are so poor that an ecstatic Wormer expels them all, having already notified their local draft boards that they are now eligible for military service. The news shocks Flounder so badly that he vomits on Wormer. Boon also learns that during the road trip Katy cheated on him with Professor Jennings.
