Halloween Party at Hillside Villas. Brody and Frankie went with Batman (Frankie) and Robin (Brody). Frankie wants to take off his cowl, because it's hot, and they bicker. Lauren, dressed as a flapper, giggles at them. Lauren looks surprisingly good with dark hair and dark lipstick. Whitney says that the boys look "more like Siegfried and Roy." Whoa! Whitney with an actual joke, if sort of dated. The girls have a smoke machine in their tiny apartment, which seems like a bad idea. Jenn Bunney is there, and holy nose job! How did I not notice that before? Her nose is tiny now. Corey, Audrina's date, arrives. He's dressed as a sailor. What in the hell is that black thing on his lip? Audrina introduces him to Brody and Lauren. Brody says he's got to go. Lauren gives him a hug and asks if he has to leave right now. He doesn't really answer, but he does leave. Whitney gives him the stink-eye. Lauren drinks some more and looks sad. There's a lot of that in this episode.

Hillside Villas. Morning after the party. The apartment is amazingly clean, considering. Audrina mentions Brody and Frankie leaving so early. Lauren pretends she doesn't care, and brings up how much everyone liked Corey. Audrina is so happy to be going on a date with him. Lauren likes that Corey made an effort with Audrina's friends. She doesn't add, "Unlike gross JB," but you know she wants to.

Spencer and Stephanie go to the stationary store to pick up the Save the Date cards. He runs through all the elements they have planned, and mentions that they need a place for "the party," and it's SO Spencer to call it that instead of a reception because it shows that (A) he's a partier and (B) he's not tied down by the Man and (C) he's a grade-A d-bag. Stephanie, to the surprise of no one, reveals that she and Heidi talked about Spencer stomping out of the apartment the other night. Spencer can't believe that Heidi talked to Stephanie and not him. Stephanie drops the bomb that Heidi's not sure she wants to get married right now. Wow. Beeswax. None of yours, Stephanie. Spencer bails on picking up the cards, since he might not need them, and says he needs to talk to Heidi.
