Previously, on Grey's Anatomy, George and Izzie had sex. Some other stuff happened too, but the image of the very, very wrong sex has pushed everything else out of my brain.
We start with a little surgo-montage. Meredith's voice-over tells us that a patient's history is just as important as their symptoms, while we watch Burke and Cristina operate on some dude. Unfortunately, they spend more time making goo-goo eyes at each other than they do actually looking at the patient, so I don't think he has the best chance of making it out of this one alive. . . .
