Grey's Anatomy returns for Season 20 in just under two weeks and now, ABC has released a new trailer for the upcoming season that looks to be full of high stakes drama and the return of a fan-favorite who is ready to "make history" at Grey-Sloan. The new trailer, which you can check out for yourself below, features the return of Jessica Capshaw's Dr. Arizona Robbins who asks the interns who is ready to make history — but there's a lot more that those interns and the rest of the doctors will face.
