Grey’s Anatomy showrunner Shonda Rhimes has been revealing the fates of some of the doctors left stranded after the plane crash, while leaving others for the season premiere this fall. Spoilers ahead!

Rhimes previewed the medical drama’s upcoming ninth season in an interview with The Hollywood Reporter,

“I can confirm to you that Meredith, Cristina and Derek survive,” she told THR. She also added that additional deaths and departures are possible, however.

She wouldn’t comment on Arizona’s fate but did say the writers are doing what “feels completely right,” while also saying that Arizona’s fate will have a huge impact on Callie.

Rhimes also briefly described the season’s first two episodes.

“Our first episode takes place two to three months after we left the finale, so you see the aftermath and where everyone ends up,” she said. “The second episode jumps back and we’re back in the woods, we start the episode back in the woods. To me, it’s a very different way of telling the story and you have some questions about why people are the way they are and in the second episode you find out why things are the way they are.”

Grey’s Anatomy returns Sept. 27.
