Brad, after admitting he hooked up with his space camp buddy, Lana (guest star Mila Kunis), begs for forgiveness from Lily until he learns of her infidelity.

Now that Eddie is spending all of his free time with Faye, lonely Sean finds every possible thing wrong with her, including the way she parks her car, which he ""accidentally"" smashes into. Meanwhile, Lily's attempt to make Brad jealous by dating Mocha Joey backfires when Brad points out that Lily and Mocha Joey have nothing in common; and Claudia gets upset when she finds out that Sean has told everyone that she is pregnant.
