Benny and Carmen scour the campus for fake IDs so they can join the rest of the freshmen class–including certified HOTTIE Miles–at Rock Bar. Peter comes through for Benny but not even Carmen's party girl roommate, Hailee, can help her out. Peter flakes on date night at the local Italian restaurant and Grace befriends an elderly woman (for her volunteer hours, duh!). Hailee throws up.

It's Halloweekend and Benny is still on the outs with Carmen so he and Miles have been getting… closer. Carmen and Hailee reconcile just as the latter enters her bad girl era. Grace calls Peter out for treating her like an assistant. Tensions (sexual and otherwise) rise at the annual Chem Party. But who will go home with who (or is it whom)? This episode is so good.
