Thank God they just hired a world-class plastic surgeon on the day a man's face burns off. Bailey puts a mask on him as McSteamy shoots directions at Bailey. Cristina gets Meredith some water as Derek frets over her, telling her she looks beautiful, but not fine. Cristina, and the rest of the world, are now nauseated. She sends him away, "You have aneurisms to cut. And surgeons to confront," with a look at the chief and McSteamy. Derek tells Cristina to watch her and takes off to do some confrontin'.
In the singed aftermath, the Chief angrily asks Mark, "What kind of idiot lights a cigarette in a hospital?" Derek walks up and answers, "Apparently people do idiotic things all the time." TouchÃ©, Derek, but at the same time, please refrain from excluding yourself from the idiot brigade -- we've seen everything you've done for the past two seasons. The men have a three-way staredown as the interns watch. Derek chases the Chief up the stairs, Addison comes down the hall to confront Mark and tell him he can't be there, and the interns enjoy the show. Mark tells her he sublet his apartment and sold his practice, as Richard defends to Derek that he's a foremost plastic surgeon and will bring more business to the hospital than neurosurgery does. Are they all sitting around, practicing their zingers all day long? I thought they were practicing medicine. The conversations continue to overlap about why he is there, and why he left New York, and why Addison is there -- come on, let's ignore this whole "gifted doctor" crap and realize that this is Seattle Grace -- Home of Displaced Doctors, Love Triangles, and More Soap Than the Tide Factory. Meredith creates a diversion by puking again, and Cristina, ever subtle, asks loudly if she's pregnant. Again, everyone stares, she retches again, and Addison mumbles, "Oh, this is just perfect." Derek hurries to Meredith as Addison observes, "An adulterous love child." "Goes along with an adulterous sociopath." I still have no idea if he means Addison or Mark, but it has a nice rhythm, as comebacks go, even if it's not very clear. Bailey sends him away, telling him, "Uh-uh, you've done enough already," and as they lead her away, Mrs. Salesman comes out cheerfully to say she's done filling out the paperwork, and when can she take Shawnie home? Bailey is at a loss for words, one of the few times that happens.
Cristina examines Meredith, asking her who the father is. While Mer protests that she isn't pregnant, it comes out that if she is, it could only be Derek's since she hasn't slept with Finn. Cristina realizes poor Finn has lost this race already, no matter what anyone says. She coos over the idea of a "McBaby," and Meredith winces as Cristina touches her stomach, presumably from the pain and not from the idea of being a child raising a child. Bailey comes in and announces that she isn't pregnant, so they'll need to run more tests. Meredith uses the opportunity to beg for morphine.
