Probably most Grey's fans favorite writer, and favorite person for that matter, mastermind Shonda Rhimes (who hasn't written an episode since 301 "Time Has Come Today"), is the writer of the upcoming - and I quote - "challenging" episode of Grey's Anatomy, part one of three-episode arc, Episode 315 "Walk on Water." This is really exciting news and gives us even more of a reason to be excited for this episode! Also, ABC has released the official "synopsis" of the episode, which doesn't tell you anything about the episode - seriously! - but here it is anyways, for those of you that want to read it:

Beginning February 8, "Grey's Anatomy" enters a three-episode story arc that will challenge the interns of Seattle Grace -- and "Grey's" fans as well -- like never before.

I'm pretty jazzed for this episode (and the arc), and am really interested in seeing what happens. Stay tuned!
