Those signature three-inch heels are back! Private Practice won’t be returning to ABC until the fall, but fans of Kate Walsh (a.k.a Dr. Addison Montgomery) can get a quick fix May 1 when the siren returns to Grey’s Anatomy “to explore the thought that you can never go home again,” teases executive producer Shonda Rhimes. In the episode, Addison flies to Seattle Grace at the behest of the Chief (James Pickens Jr.) and she’s ready to set a few people straight. Explains Rhimes, “There are some things only Addison can do surgically, but there are also things that she can say to people that nobody else in that world will.” (In other words, prepare yourselves for a tongue-lashing, Meredith and Derek!)

Just don’t get too comfortable with her homecoming, since she’s only staying for one episode, after all. Says Walsh, “I’m here to do my business in Seattle and then I go back to the L.A.!”

Well, not immediately: Production on Practice’s second season doesn’t start until sometime in May, which gives Walsh enough time to costar as a “crazy lady” in the supernatural thriller Legion opposite Paul Bettany. (It’ll also give Rhimes a chance to find a new exec producer to help her run Practice, though she’ll still serve as head writer for both of her series.) Practice was this season’s most popular new drama before the writers strike sent it on hiatus, but the break may have been a blessing in disguise, says Walsh. “How do you promote it when American Idol is on?!” she asks of the series that Practice would have faced had it remained on the air. “I’m cool with coming back in the fall.”
