"Grey's Anatomy" is one of the best medical dramas of all time, and is currently airing its whopping 20th Season on ABC (and streaming with a Hulu subscription). But there's a problem: "Grey's" keeps losing cast members, and we're getting really frustrated.

Because of how long "Grey's Anatomy" has been on television, we've see a ton of main characters come and go. But lately it feels like every time we get attached to one of the surgeons at Grey Sloan Memorial Hospital, they end up leaving. Not even counting Ellen Pompeo's departure as a series regular, this has happened time and time again. It was just revealed that Mika Yasuda actress Midori Francis will be departing next season, after just two seasons as one of the surgical program's new interns.
