Davis will reportedly enjoy a "major arc" as a new surgeon, a character who’ll perhaps take the place of Dr. Cristina Yang (Sandra Oh, who left the series last season).
Also returning to the show will be Kate Burton as protagonist Meredith’s mother.
Shonda Rhimes has previously announced that the upcoming season will give Ellen Pompeo much to do: "It’s really a Meredith-centric season. There’s a lot of growth. She’s lost her person. Her sister has showed up. Her husband is chafing to go someplace else. She’s got all these things going on. … But for me right now, it feels like it’s Meredith. I’m feeling her more acutely because she’s lost her person."
