Another season of Grey's Anatomy (No. 14!) is ending, and as usual the May 17 finale promises lots of drama, including a long-awaited wedding… and a couple of tearful goodbyes. (Spoiler alert: So long, April and Arizona!)

But while recently chatting with Entertainment Tonight about April and Arizona's "devastating" last episode, star Ellen Pompeo (aka Meredith Grey) revealed that sometimes a character's send-off is determined by the actor who plays them. Only those whose "behavior is bad" get terrible exits, said Ellen, 48, adding that "if you're a nice actor, you die nice." So, In Touch Weekly in the magazine's new issue, on newsstands now! — analyzed all the past Grey's stars' final scenes to see if we can separate the naughty from the nice. Scroll down to see!

Preston Burke

On the show: Dr. Burke left his fiancée (Sandra Oh’s Cristina Yang) at their wedding after deciding that they didn't really love each other.

In real life: Isaiah Washington was fired in 2007 after an on-set fight with Patrick Dempsey allegedly turned physical and he used a homophobic slur to insult co-star T.R. Knight.

On the show: These docs' exits "aren’t tragic," promised Ellen. (Sure…)

In real life: In March, rumors swirled that Ellen's new deal ($20 million for two more seasons of Grey’s) led to the dismissal of Jessica Capshaw and Sarah Drew, which showrunner Krista Vernoff denied.

Derek Shepherd

On the show: McDreamy was mowed down by an 18-wheeler. Ouch.
