This season of Grey’s Anatomy has had an impressive line-up of guest stars, from seasoned actress Kate Burton returning as Ellis Grey in Season 8, Episode 13: “If/Then,” to Peri Gilpin and Nia Vardalos playing sisters in Episode 12: “Hope for the Hopeless.”

We personally loved seeing one of our favorite thespian queens, Alfre Woodard, play a novelist in Episode 8: “Heart-Shaped Box.” Especially going one-on-one with the far less bold Lexie (Chyler Leigh).

Who has been your favorite so far?
