Gaby is cast in a student film, but the scene requires her to kiss Jack.

Halloween at the diner finds Michael trying to prove he can be shallow when it comes to his sex life after the others find out he has never had a one-night stand, and Gaby wanting to be open-minded about a very tall guy who fancies women's clothes.
