ABC has released a Grey’s Anatomy teaser showing the first new, albeit brief, footage of the upcoming season.

The promo asks: “Who will survive?” while clips from the season 8 finale (“the most devastating event of their lives”) flash through the screen, along with footage of someone being taken into surgery at a hospital that may or may not be Seattle Grace.

At the end of season 8, Meredith, Cristina, Derek, Arizona and Mark were left mourning Lexie’s death. Mark and Arizona had seemingly life-threatening wounds, while Derek’s hand suffered a major injury as well.

Creator Shonda Rhimes has stayed mum about the fates of Mark and Arizona (while revealing other plot lines and developments in a spoilerific interview with THR), but Eric Dane (Mark) has confirmed he will be departing the show. In what way? That remains to be seen, though Patrick Dempsey tweeted some spoilers in July.

Grey’s Anatomy returns to ABC Sept. 27 at 9 p.m. ET. What do you think will happen to Meredith, Cristina, Derek, Arizona and Mark? Share your season 9 theories below.
