Without giving anything away, I will simply say this is an episode to watch. Between Meredith's sympathy for a murderer, Izzie being clueless about her diagnosis, learning how important organ transplants can be, and finally, for me, it was the scene in the OR with Derek and Bailey. She was outstanding. You knew with every ounce of her she wanted the patient to die, but just couldn't go through with Derek letting him die. Chandra Wilson gave an excellent performance.
