It is Penny's last day and Al thinks a few party games are in order. Elsewhere, Tarks finds himself in grave danger when someone decides he should be punished properly for what he did to Alia. Valerie ignores Emma's advice and then learns the hard way that she can't always have her cake and eat it too.

Rob and Addison question their new suspect. The suspect denies running Tarks over and claims to have an alibi but won't say who it is. Are they protecting someone? Meanwhile, tensions are also running high at the Carter house, and new accusations are made. Ruhma and Heston now wonder if Farah is actually guilty - maybe someone here did it after all.
