Thank the TV Powers That Be for Patrick Dempsey (Derek Shepherd)! The Grey's Anatomy star recently tweeted a couple of set photos that give as a very tantalizing sneak peek into what's coming up on Season 9.

On November 21, Patrick tweeted about having a "long day" on set, and later posted the set photo to the right, saying "Dinner time." In the photo we can see Patrick, Ellen (Meredith Grey), Sandra (Cristina Yang), and we think Jessica Capshaw (Arizona Robbins) and Sara Ramirez (Callie Torres) sitting around a dinner table. They're all dressed nicely.

The question is: What's going on? We know the cast is already filming episodes for after the winter hiatus, so it can't be Bailey's (Chandra Wilson) wedding, which is, as far as we know, coming up before the break.

The day before (November 20), Patrick also tweeted the photo to the left, showing Jessica Capshaw and Sara Ramirez in what looks to be a courtroom. Our guess is the docs finally go to court over the plane crash. Perhaps the dinner is a celebration of their success during the trial?
