Over the course of the two decades it’s been on,Grey’s Anatomyhas lost more than its fair share of key characters, but some departures have stung more than others, for how abruptly they happened or how their consequences changed the medical drama. With only three original characters still consistently part ofGrey’s Anatomy’s central story, more characters left than those who stayed at Grey Sloan Memorial. WithGrey’s Anatomybecoming known for killing off its main characters, some of its most upsetting departures involved key characters brutally dying, or doing so gratuitously, as their exits were already set up.

However, some departures were upsetting even if the characters leaving didn’t end theirGrey’s Anatomystory dead, but their departure greatly changed the medical drama or impacted other characters extremely negatively. This was the case for at least two original interns’ exits.Some characters’ centrality ensured that their departure could have only entailed their death, as it would have been unbelievable that they’d stay away after their role in the medical drama. Other departures proved upsetting because of how incredibly unfair it was for their storylines to end like that, makingGrey’s Anatomy’s most upsetting departures so for different reasons.
