In this episode, we meet a new doctor, new patients and experience some operating-room drama. Dr. Rey returns with a new 'do, some old family issues and a patient who hasn't exactly been telling him everything he'd like to know. Dr. Li is still working hard- even though she's seven months pregnant and worrying her husband. And we meet Dr. Paul Nassif and watch the emotional journey as he helps a woman achieve her dream. Oh, did we mention the trip to Vegas, the porn star and the implants?
