Ben finds that studying with Sarah isn't as much fun now that they aren't dating. Maggie thinks about returning to Chicago, while Dia and Kelly talk about getting engaged.
Ben has a crush on the new girl who works at Swim Cafe. It's hard to tell whether she finds his flirting charming or annoying. Meanwhile, Noah's relationship status is quite different than the last time we saw him.
Maggie tells Ben that she's moving back to Chicago, but he's not thrilled to discover who her roommate is going to be. Dia turns Kelly's back rub into a full blown boob massage.
Ted greets Maggie upon her return to Chicago, but when he disappears into Ben's bathroom, everyone is left wondering what he's doing in there. On the other side of town, Noah lets Owen try a new position.
Ben tells Sarah about "boyfriend voice" to help explain why he didn't answer the phone in front of her. Things get sexy when Natalie tells him about auditioning for "The Secret World of Alex Mack."
Noah and Owen spend a lazy morning together, then Noah introduces Kelly to the viral sensation, "2 Girls 1 Cup." Shopping for an engagement ring doesn't quite go as Dia planned.
Noah helps Ben freshen up his "tattoo," but Ben has bigger problems to deal with. Is it possible for he and Sarah to be friends, or are their feelings for each other too complicated?
Kelly finally pops the question to Dia, and Natalie asks Ben an interesting question of her own. Not wanting to be left out of the action, Ted has a question for Maggie, but her answer may not be truthful.
