It's the ZBZ Formal and Casey and Max decide to go together. At the event, Ashleigh and Rusty bond. Also, Rebecca decides to skip the event claiming she needs a break from sorority events.

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.
