Showrunner Shonda Rhimes has told THR that she wants Addison and Amelia to re-appear on Grey's Anatomy.
"I've said a million times that before the show ends its run, Addison has got to put on her shoes and scrub cap and come scrub in at the hospital. That's a given for me."
Amelia is Derek's sister and I'm going to want to see that happen at some point as well."
Kate Walsh (Addison Montgomery) and Caterina Scorsone (Amelia Sheperd) just finished the final season of Private Practice early this year. There are no plans for Walsh and Scorsone for the moment but Rhimes affirms that they're both ""always going to be a member of that family."
