Private Practice star Caterina Scorsone, who plays Derek Shepherd's (Patrick Dempsey) baby sister Amelia Shepherd in the ever-expanding universe of Shonda Rhimes, visits Grey's Anatomy tonight as part of a big crossover event...but before she hit Seattle Grace, she stopped by to chat with me! Press play above to find out whether or not she has sexual chemistry with Eric Dane, why her character once struggled with addiction and what tonight's episode reveals about her (and Derek's) troubled family.
Juicy, yes? How do you like Caterina's character so far? Are you excited to see her get to know Meredith (Ellen Pompeo), aka the second Mrs. Dr. Shepherd, despite her close relationship with Kate Walsh's Addison, aka the first Mrs. Dr. Shepherd? Hit the comments!
