Grey's Anatomy Grey's Anatomy

The Grey's Anatomy docs are Lost!

No, seriously. The plane crash recalls the days of the ABC mystery island series, complete with an injured leader (Ellen Pompeo's Meredith), an unfortunate tailie (Chyler Leigh's Lexie) and a missing husband (Patrick Dempsey's Derek), who fortunately is found by the end of the opening act. But he's not — pardon the pun — out of the woods yet. Plus: Arizona (Jessica Capshaw) has a nasty injury, and Cristina (Sandra Oh) and Mark (Eric Dane) are trying to save the pinned-down Lexie. And that's only the first six minutes!

Lest we forget, someone will die during this hour, so watch the first act of the gruesome and terrifying finale below and hit the comments with who you think won't make it out alive.

The Grey's Anatomy finale airs Thursday at 9/8c on ABC.
