It's a team effort and a family affair on the Grey's Anatomy-Private Practice crossover event January 14, 2010. Can Sloane be helped when Mark and Addison join forces?
Kate Walsh (Addison) is back on Grey's Anatomy, but still on Private Practice, of course. She stars on one Shonda Rhimes series after getting her start on the other.
