Casey returns with secret plans to move out of the ZBZ house; a new freshman is highly desired as a pledge; Rusty tries to balance studying with life in the Kappa Tau house.

Now a sophomore, Rusty gets to participate in Rush Week for the first time and he is determined to land Andy as a pledge for Kappa Tau, but Calvin feels the pressure from Evan to get Andy to pledge Omega Chi. Who will prevail in the battle for the big man on campus? Ashleigh and Casey start to doubt Rebecca's "mole" abilities and begin to question whether she's actually a double-agent for Frannie's new sorority when the ZBZ girls’ rush week “Project Runway” fashion skit is successfully sabotaged by Frannie.
