Patrick Dempsey stopped by the racetrack at Homestead, FL, yesterday and this morning to practice before the Rolex Series race he'll be driving in this weekend. Patrick's passion for cars is his hobby when he's not filming Grey's Anatomy, which had a pretty dramatic episode last night. Derek stays by Meredith's side as she decides whether to donate part of her liver to her father, while Izzie deals with the complications of returning to surgery. There are lots of changes coming up for the doctors of Seattle Grace including the addition of Kim Raver to the cast — chat about everything that's going down in our Grey's Junkies community group.
