Malibu. Whitney and Lauren chill poolside and realize that they don't know anyone at the party. Audrina and Corey are hanging all over each other in the pool. Lauren and Whitney talk about the new couple. Lauren can't say enough nice things about Corey, and how he's nice, but he also has an edge, and how happy he makes her. Frankie and Doug show up and Frankie reports that JB might show up. Lauren wants them to tell him not to show up. Frankie calls him and Lauren tries to get him to tell JB not to come at all. Frankie leaves a ridiculous message. So then they discuss Cabo, and apparently the guys invited JB to come, so they wonder if Audrina will bring Corey or what. Frankie walks over and asks Audrina about Cabo. Audrina takes this as an opening to complain about how JB treats her, and how Corey treats her so much better. She keeps whining and whining like she had no control over how JB treated her for all those years. So Frankie drops the bomb: Brody invited JB to Cabo.
Audrina and Lauren go for a hike with the dog. Holy crap! That little puppy from last season is HUGE! Super-cute, but huge. Audrina starts babbling on and on about the JB/Corey dilemma. They agree that JB has some sort of radar that lets him know that Audrina is getting happy with someone else, so he starts calling her. Lauren doesn't know what advice to give, but she tells Audrina that JB's probably not going anywhere. I'm pleased to see that Lauren has one of those poop bag attachments for her dog's leash, so presumably she picks up after he takes a dump. I approve.
