Turns out Frannie hasn't completed ANY of the pre-reqs for her major (pre-med, can you believe it?). If she ever wants to graduate, she'll have to do a fifth year. What does Frannie do? Hit the books? Get a tutor? Nope! She sets her sights on winning Omega Chi Sweetheart, again. Of course, Casey will just have to drop out to spare the sorority the pain of seeing two sisters compete. Casey's ready to do that, but Evan thinks she's making a big mistake. Frannie's had her turn; it's time for her to exit the stage. Evan already has a sweetheart, and so do the boys at Omega Chi: Casey. So, Casey stays in the race, and Frannie declares war.

Cappie has some debts to pay (like that bar tab Casey picked up in Episode 8), so he signs up to be a guinea pig in a sleep-deprivation study. Guess who his undergrad supervisor turns out to be? Rebecca Logan. She tries to keep it professional but can't help needling him about Casey and Evan. Not even Rebecca's bitchitude can resist the power that is Cappie -- especially when she's locked in a room with him for 30 hours. By the time the experiment is over, the ice has definitely thawed.

Rusty and Jen K. can't get enough ... sex. And Dale -- surprise! -- is cool with vacating the room for the lovebirds. Love the sinner, hate the sin, ya know? But Dale's other cheek doesn't stay turned for long. Rusty takes Jen to a physics lecture that Dale had planned as a geeks-night-out with his roomie. Spurned and betrayed, Dale ups his passive-aggressive game to Def Con V, and Rusty starts looking for a new roommate.
