Grey's Anatomy teases the return of another past character in season 17

By Katie Louise Smith

Who left and who got fired? Here's what happened to 15 of Grey's Anatomy's biggest stars and their reasons for leaving the show.

Grey's Anatomy has been on air for 17 seasons and, in that time, it feels like we've said goodbye to more characters than we've all collectively had hot dinners.

With the exciting news that more past characters will be returning to the show amid Meredith's (not so exciting) COVID-19 storyline, it seems like the perfect time to take a stroll through memory lane and revisit those we've loved (or perhaps, not loved at all) and lost.

From the shock departures and the dramatic firings to all the fake doctors we've said goodbye to in between, here's every main cast member who has left the show and the reason why.

Why did Justin Chambers leave Grey's Anatomy?

(Chambers played Dr. Alex Karev from season 1 to season 16.)

Chambers announced his unexpected departure from the show in the middle of season 16, after his final episode had already aired. He also didn't return on-screen for Alex's farewell episode. There's been no explanation as to why his departure was so abrupt. In a statement to Deadline, Chambers said: “For some time now, however, I have hoped to diversify my acting roles and career choices. And, as I turn 50 and am blessed with my remarkable, supportive wife and five wonderful children, now is that time.”

How was Alex Karev written out?
Alex was last seen in season 16, episode 8. It was revealed that he had reunited with Izzie Stevens, leaving his wife Jo, his job and Seattle altogether.

Why did Patrick Dempsey leave Grey's Anatomy?

(Dempsey played Dr. Derek Shepherd from season 1 to season 11. He returned in season 17.)

There was a lot of drama surrounding Dempsey's departure from the series, although most of it was based on speculation. Despite rumours of a rift between him and Shonda Rhimes, Rhimes revealed that the decision came from a mutual discussion. Ultimately, Dempsey stepped away from the show to focus on himself, his family and his passion for racing. He told People: "It had been long enough. It was time for me to move on with other things and other interests. I probably should have moved on a couple of years earlier."

How was Derek Shepherd written out?
Derek was driving when he stopped in the middle of an intersection and was hit by a truck. He was then taken to an ill-equipped hospital where the doctors failed to give him a head CT. He ended up brain dead, and Meredith later agreed to take him off life support.
