[UPDATE] TVLINE | What can you tease about the season finale?
There is a huge story that happens. For half of the people, it happens outside of the hospital, and then the other half are in the hospital and don’t know that this big thing has happened. It will forever change everybody’s relationships. I am on the edge of my seat because I want to know what’s going to happen at the beginning of Season 9. [Laughs] It is that gigantic of a cliffhanger. It’s really intense, really emotional. Everyone was crying and shell-shocked at the table read. It’s huge. - TV Line
Please tell me you have more info on the big event in the Grey's Anatomy finale! — Sammy
NATALIE: Sarah Drew echoed Shonda Rhimes' ominous sentiments: "It's on par with the shooter finale," she says. "It will affect everyone, but it happens outside of the hospital, and the people that are at the hospital don't know it's happened yet by the end of the episode — I'm one of the people who is back at the hospital. Everybody is left with an uncertain future." Any guesses yet? - TV Guide
Question: Is there any thing you can share about Grey’s Anatomy — like who’s going to die in the finale? —Nikki
Ausiello: “Everybody’s in jeopardy,” teases Sarah Drew (April) of the May 17 climax. “There are three or four people who are not [involved] in the cliffhanger at the end of the episode. But every other cast member, like nine of us, are all in this — [so] who knows what’s going to happen, whether they’re going to be back or not.” Drew likens the episode, tellingly titled “Flight,” to previous Grey’s catastrophes “like the ferry crash or like the shooting… it’s that kind of a season finale. It’s big, it’s intense. It’s scary. It’s emotional. It’s exciting. All of those things. It’s a big one.” - TVLine
