The intern, now residents, deal with their own crops of intern. Callie struggles with her new position, and Burke makes a decision.

After failing his exam, George reluctantly faces his first day reliving his internship among a sea of fresh faces. Meanwhile, Cristina, Meredith, Izzie and Alex are in charge of their own interns and George is assigned to Meredith.
　　Neither Cristina or Meredith have heard from her exes since the wedding, and they don't seem overly concerned, which astounds Izzie, who is counting every day since she last spoke to George. George asks to talk to Meredith but before he can get her alone, the rest of the new interns show up in the hall and are shooed off by the residents. George gives up and joins the interns. Cristina nicknames him "Bambi," saying he needs to learn how to deal with his new situation.
