Grey's Anatomy Season 10 spoilers alert! There will be a special Cristina Yang episode, and Preston Burke will be returning to the TV show.

The Cristina Yang episode is meant to be a last hurrah for actress Sandra Oh, who plays the complex surgeon. She announced her departure from the medical drama last August after playing the character for the last 10 years. Her contract expires at the end of Season 10, which will be her last. She told Hollywood Reporter, "Creatively, I really feel like I gave it my all, and I feel ready to let her go. It's such an interesting thing to play a character for so long and to actually get the sense that she wants to let go as well. Cristina wants to be let go, and I am ready to let her go. We have to start the process, story-wise, for the Grey's writers to think of why she's going to go." TVLine reports that the episode, which will air on March 27, will reportedly be titled "Do You Know."

Now ABC and Grey's Anatomy creator Shonda Rhimes has confirmed that one of the show's original actors, Isaiah Washington, will be coming back for one episode. He will be once again stepping into the shoes of his old character, Dr. Preston Burke, who was Dr. Cristina Yang's first love interest.

Washington had a controversial exit from the show in 2007, when he let loose a derogatory term at the Golden Globes press room. It was also reported that he had differences with his co-stars Patrick Dempsey and T.R. Knight. Rhimes explained that he is needed for the special episode, because his return will give Cristina Yang's departure a full-circle moment. "It is important to me that Cristina's journey unfolds exactly as it should. Burke is vital to that journey."
