The plot surrounding Sandra Oh’s impending Grey’s Anatomy exit has thickened considerably.

Isaiah Washington is set to reprise his role as Cristina’s ex, Dr. Preston Burke, in one May episode, TVLine has learned.

“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.”
