If the prospect of Bailey's (Chandra Wilson) wedding jitters and more from Derek's (Patrick Dempsey) sister isn't enough to get you excited about this week's Grey's Anatomy Season 9, Episode 9: “Run, Baby, Run” (December 13), maybe a new tweet from showrunner Shonda Rhimes will be.

Yesterday, December 10, Shonda tweeted, "This week's @GreysABC is one of my all-time fave episodes EVER in our 9 years. Written by Debora Cahn and directed by Rob Corn. Yay!"

Wow. Given the number of awesome, uplifting, heartbreaking, and just plain dramatic episodes Grey's has had over the years, our expectations are suddenly super high for the Season 9 winter finale. We're excited to see why Shonda loves this episode so much.
