(about Carter being mad at Susan for staying over at Mark's)
Luka: Abby's been sleeping on my couch. Nothing's happened.
Abby: Yeah. I needed a place to stay till I found a new apartment and Luka said I could stay with him.
Susan: You're probably more upset about that than me staying at Mark's.
Carter: No, I'm not.
Susan: Right! (to Abby) Carter is still stuck on you.
Carter: Can we change the subject?
Susan: Ahh, now you want to change the subject!
