Heidi takes Holly to the salon. Holly pumps her for information on why she hasn't told her mom about her relationship with Spencer. Heidi claims she's an adult and doesn't need her family all up in her relationship. In other words, Spencer's a controlling prick who's systematically forcing Heidi to cut off her support systems. Holly asks if Heidi misses Lauren at all, and Heidi is noncommittal. Holly is concerned that Heidi has sacrificed too much for her relationship.
JB shows up at Audrina's party. Lauren and Doug cuddle poolside and then Lauren leaves to find Lo, who is kind of hiding inside, playing with the dog. Lauren wants Lo to hang out, but Lo complains that she doesn't know any of Audrina's friends, and that she's making an effort and Audrina doesn't reciprocate, so she's over it. Lauren thinks it's the same for her, but what she doesn't get is that she cares and Lo doesn't. There are a few shots of Audrina's friends getting rowdy and throwing each other in the pool. Lauren goes outside and complains to Frankie that Lo and Audrina aren't getting along. Frankie suggests that Lo and Audrina don't have to be friends, but Lauren wants things to go back to how they were.
Time for Holly to leave already! Heidi and Spencer walk her out. Holly "spontaneously" brings up that she might come back to L.A. since she has no reason to stay in Colorado. Spencer is silent but brooding. Heidi offers to let Holly stay with them until she gets settled. Holly thanks Spencer and drives off. Spencer is all pissy that Heidi offered to let her SISTER stay with them for a couple of weeks. What, is she going to cramp his style when he's busy all day playing Xbox and calling tabloids and paparazzi to document his next staged photo shoot with Heidi?
At work. Lauren tells Whitney that Lo kind of blew off the party and it was awkward. Lauren says that Doug was there, and was really nice, and she couldn't really focus on him because she was stressed out about her roommates. So Lauren told Lo to talk to Audrina. That should fix things right up, no?
