“It’s important to me that Cristina’s journey unfolds exactly as it should,” said series creator Shonda Rhimes in a statement. “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.”

Washington was pink-slipped from Grey’s after Season 3 wrapped, in the wake of a months-long controversy that started with an October 2006 on-set incident in which he allegedly referred to castmate T.R Knight with a homophobic slur — and then he repeated said slur during a cast appearance at the Golden Globes.

Washington’s character had already effectively been written out in the Season 3 finale, after Burke left Cristina at the altar.
