Dr. Cox returns to the hospital, but Elliot quickly learns the hard way that he's still his same old obnoxious self. And Carla forces Turk to also give up the things she has to give up while she's pregnant.
- Clip Show: A variation. While this episode uses a lot of dialogue and jokes from previous episodes, they are reenacted by the cast, and not shown in clips.
- Déjà Vu: The concept of the whole episode relies on this. See Clip Show above.
- Meaningful Echo: Way back in season one, after keeping his job, Cox declared himself bulletproof. This time he admits to Elliot that he needs people to see him the way they used to, bulletproof.
- Shout-Out: JD sets up a welcome back with the staff singing the theme to Welcome Back, Kotter while wearing shirts with Cox's face with a fro saying "Welcome back Coxxer.".
