Well this should be interesting. Isaiah Washington is returning to Grey's Anatomy! He really hasn't really worked since his debacle a few years ago when he went on a tirade on set. Shonda Rhimes is a very powerful woman, and when you cross her, she will make sure the rest of the industry knows what you did.  (Same thing happened to Katherine Heigl). 

He guest star on an episode of the show (in May) to help say farewell to Sandra Oh, when  her character Cristina leaves the show. If you remember, Isaiah was fired from the show for on-set clashes with cast and crew and for the anti-gay remarks he made directed at his then-closeted co-star T.R. 

” Shonda Rhimes said in a statement (via THR). “It’s important to me that Cristina’s journey unfolds exactly as it should, “Burke is vital to that journey — he gives her story that full-circle moment we need to properly say goodbye to our beloved Cristina Yang.”
