Grey's Anatomy (ABC) Returns Thursday, April 24 at 9 p.m. So Far This Season: Meredith (Ellen Pompeo) and Derek (Patrick Dempsey) have continued their rocky ride, with the latest bump coming in the form of surgical nurse Rose (Lauren Stamile). George (T.R. Knight) and Izzie (Katherine Heigl) finally decided that their affair was doomed, Cristina (Sandra Oh) gets her butt kicked by new surgeon Dr. Hahn (Brooke Smith) and Alex (Justin Chambers) first attracted and then repelled Meredith's sister Lexie (Chyler Leigh). Also, Bailey's (Chandra Wilson) marriage is in trouble. When It Returns: In her blog, "Grey's" creator Shonda Rhimes cryptically mentions an exploding cornfield. Mmm-kay -- maybe she was speaking hpyothetically or metaphorically. Also, we know Addison (Kate Walsh) will be making a visit to Seattle since her "Private Practice" is currently idle.
