The Big I Haven't Got the Vegas Idea Episode

Mona tries to find time alone with Nick, but her mother and Dee Dee cant seem to get the message. Dee Dees longtime friend Aurora comes for a visit. She was once extremely obese, but has now experienced a dramatic weight loss, thanks to a gastric bypass surgery. She is not used to having men pay attention to her, and Dee Dee worries about the fact that she seems to overreact whenever someone pays her a compliment. Meanwhile, Spencer tries to get over his break-up with Camille by hooking up with virtually every woman in the Bay Area. Dee Dee tries to keep him away from Aurora, as she believes she could get hurt. Adam is upset when everyone begins to bail out of his big ""28th"" (or 27th, 26th, 25th or 23rd) birthday bash in Las Vegas. Spencer and Aurora wake up naked and hung over in a Vegas hotel room, and Adam tells them they got married. A panicked Dee Dee, unable to find Aurora, interrupts Monas romantic weekend with Nick.
