Housewarming! They totally have an in-ground pool. The girls prepare for the party with sliced limes and lemons. Audrina says that JB is coming, and Lauren wants to talk about it. Audrina just awkwardly stands there and Lo brightly says that JB might wear his cowboy hat. Audrina just awkwardly stands there some more. To lighten the mood, Lo brings up the fact that Lauren invited Stephen Colletti. Audrina finds her voice again and this time Lauren is the one who doesn't want to talk about it. What is with Audrina's passive-aggressive attitude about JB? Like if she doesn't want her friends to talk shit about him, tell them. She is such a victim.

The party has begun! And Harpo Marx is there! Seriously, there's some dude with a massive blond Afro. Whitney arrives! Aw, we haven't seen Whit in a while. Brody shows up with his new girlfriend, Cora, and Frankie. Brody introduces her to Lauren, and Lauren is all fake smiles.

Stephanie specifically goes over to Heidi's apartment to tell her that she's going to Lauren's housewarming party. Why go over there first? TV drama. Stephanie says that she felt guilty about it but she thought Heidi would be okay with it. Heidi pulls a total Spencer and claims that Stephanie only feels guilty because she knows she's doing something wrong. I'm still rooting for the She-Pratt to totally pull a double-cross. Heidi gives Stephanie the same "loyalty" speech that Spencer just gave her. Stephanie is all dejected and mumbles something about middle school and then says that she won't go if it means that much to Heidi. So they decide to watch a movie. BORING!
