Izzie is in the clinic where Graciella eagerly asks if they are going to be able to scrub into a surgery. Izzie tears them all a new one when she asks if they really think they'd be allowed to do that when they could barely finish the Intern Bowl? She then turns around and laughs really smugly to herself. She's confronted by a woman who turns out to be the patient that she and Sadie learned had cancer. The only thing is, after consultations with different doctors and a round of tests, it turns out that she doesn't have cancer, she's only anemic, but it took $80,000 in medical tests to figure that out. As a result, she's suing the hospital. Just in case we don't get it, she explains that her lawyer figures that her blood was switched with someone else's that day. He told her not to come there, but her conscience told her to come so that Izzie can figure out what poor soul might have been told she was anemic but really has cancer. Hmm, who's blood was sent to the lab at the same time that day? Izzie apologizes, but the woman bashes her over the head with, "Don't apologize to me, I'm just anemic! You apologize to that dying person." Cut to Izzie, sitting in a desk chair and looking worried, then pulling out her own test results that diagnosed her with anemia.

Derek is working away when Alex and Addie notice that the baby is going into distress and Jen's blood pressure is dropping. He tells Addie to wait but she says the baby needs to come out -- 4 surgeries in 3 days are a lot for an unborn baby to handle, as it turns out. Derek keeps telling her to wait since the baby is too young, but finally she decides to go in while Derek aggressively tells her to leave the baby in. Just as she's about to cut, Derek triumphantly says he's done. It's a little alarming how much his voice says he's happy to be right instead of Addison, and not just because of his patient's life and all that extra hoo-ha.

Callie has patched her patient's ankle, as it's just a fracture that doesn't need surgery. I think his name is John -- but even if it's not, that's nice and easy, right? John it is. He's self-deprecating and sweet, and Campbell tells him that if he felt something wasn't healing he should have called. She then turns to Cristina and asks what she thinks Campbell should have done to avoid this complication. After some prodding, she launches into a clinical medical explanation and Campbell tells her, "In human, please, Dr. Yang." Cristina takes a moment and announces that the surgery should have been done laproscopically. Campbell then turns to Hunt and asks him why she would do it the way she did, and he explains things like being able to see what you're doing. Oh, details. But Hunt finishes, "It's half a dozen either way," and both women are left unhappy. John loves Dr. Campbell, though, and trusts her decisions. Campbell instructs Cristina to take him to CT and snarks that maybe she'll learn something, while she and Hunt work on a treatment.
