Neve Campbell: Patrick Dempsey's 'Grey's Anatomy' Sister!
The 39-year-old actress will star in at least two episodes of the show, though it is not clear which of Derek’s four sisters she will play yet, according to TV Line.
We can rule out Amelia and Nancy as they have already made appearances, so it will either be as Kathleen the psychiatrist or the unnamed fourth sister.
Neve and Patrick previously played lovers in Scream 3.
