We've heard a lot about the Cristina-centric March 27 episode of Grey's AnatomySeason 10, Episode 17: "Do You Know?" — and now we have ABC's official synopsis. The plot description doesn't reveal too much, but the cast and crew listings do.

Here's the not-too-surprising summary:

Cristina imagines the two routes her life can take based on one decision she makes. Meanwhile one of the hospital’s patients decides whether or not to live.

So it sounds like the episode will ground Cristina's heady, hypothetical life-journey with the usual patient-of-the-week storylines.

But ABC's press release also reveals other nuggets of information — like that Chandra Wilson (Miranda Bailey) directed the episode! It's the actress's tenth time behind the camera. She's an accomplished actress and director — what a renaissance woman!

This chapter was written by Stacy McKee, a longtime executive producer of the show who has written nearly two dozens episodes so far — responsible for such defining moments as Derek's marriage proposal in "Elevator Love Letter," the heartbreaking demise of Mandy Moore's character in "These Arms of Mine," and the swoon-worthy Calzona nuptials in "White Wedding."

And the guest stars for this episode include Covert Affairs star Anne Dudek and Mad Men fixture Charlie Hofheimer — who will play Elise and Jason Castor for Grey's.

We just can't wait for the first footage from the episode — which we'll of course share with you as soon as we lay eyes on it!
