Following the traumatic events of the May finale -- a crazed gunman shot and killed several of the hospital staff in his quest to take Derek's life in retribution for the death of his wife at the surgeon's hands -- Dr. Perkins (James Tupper), a trauma counselor, is brought in to help in the recovery and to assess each doctor's readiness to return to work. And Derek, who was shot and survived as a result of emergency heart surgery done by Cristina (Sandra Oh), makes a spontaneous decision to resign as Chief and rushes back into surgery.
Patrick tells Samantha that his reaction on reading in the script that he was shot was: "I thought I was off the show quite honestly. Look at a couple of years ago what happened here."
There is also going to be a surprise wedding on the season premiere when Owen and Cristina get married.
Owen, of course, was torn between Cristina and Teddy (Kim Raver) until Cristina's life was in jeopardy. Then as Kevin says, " He made a definite choice by the end…"
But that doesn't mean that "Grey's Anatomy" will be without a love triangle. There is still the unresolved, romantic goings-on between Mark, Lexie (Chyler Leigh) and Alex (Justin Chambers).
So what does Eric think about Mark's chances of getting the girl? " If [Alex] dies," he tells Samantha.
The new season of "Grey's Anatomy" premieres Thursday, Sept. 23 at 9 p.m. on ABC.
