I Spy With My Little Eye . . . Several More Grey's Anatomy Characters Returning in Season 17

Welcome back George O'Malley! In the Dec. 3 episode, T. R. Knight made a return after leaving the series in season five. Though George has been gone for a long time now, if Meredith is going around talking to all her dead loved ones on a beach, he would obviously be one to show up! As the two reminisce on the beach, Meredith confesses that George's friendship had such a profound effect on her — it's one of the reasons she's become such a selfless person.
