McDreamy finds George in the locker room getting ready to leave. "Nice work today, O'Malley," he says. "Hey, did Meredith go home with Izzie?" Nice one, Derek. Super smooth. Not obvious at all. George says she did, and he's headed there now. McDreamy says he'll go too. What?! George says Izzie probably isn't up for a lot of people, but McDreamy says he's going to see Meredith.
McDreamy opens the door to find an IDC guy wearing a hazmat suit. He asks if McDreamy is the person who performed surgery on Mrs. Toussaint today. IDC Guy explains that she and her husband may have been in close contact with a victim of the plague, and been exposed -- which means that they may have been, too. McDreamy says he has to go, but IDC Guy blocks the door. He says the room they're in will be sealed off until the threat has been contained, and they're sure everyone is safe. Ha! George and McDreamy stuck in a room together. There's surely going to be some kind of whining/ego showdown. IDC Guy tells them they're quarantined, and slams the door in their faces. Commericals.
We return to Bailey informing Webber that everyone in contact with the Toussaints has been quarantined. She says Shepherd and O'Malley are not happy, but everything's under control if he needs to get back to his wife. Yes, I'm sure he can't wait. Webber's all, "Oh, no, no. I need to stay on top of my hospital. Keep me posted." Bailey just rolls her eyes.
