Grey's Anatomy Season 9 doesn't premiere until September 27, 2012, but that hasn't stopped ABC from releasing some tantalizing teaser promos, and this might be the best one yet.

Although this promo is mostly footage from Season 8, Episode 24, "Flight," it does include a new scene: Someone being rushed into the hospital on a gurney.

Over these troubling images came the words "The most devastating event of their lives" and "Who will survive?"

Are you worried? Because we're worried. It sounds like the start of the season isn't going to be easy to take at all. Check it out below.
