Meredith and George whisper with each other and stare down the hall at the intern drama -- Pierce looks pissed and is trying to talk to Megan while shoving Steve out of the way. George logically figures they have to talk to them but Meredith comes up with a novel excuse -- they are professionals, and this dispute is clearly personal so they should leave it be. Also, if they dealt with this they'd miss watching the face transplant and Cristina's surgery. George agrees that this is a good point, but both are clearly just grasping for any excuse to not take charge. They walk off, and Bailey looks around a computer monitor where she's been working with a, "What the hell?" look on her face at the retreating residents.
Mark and the gang are going over some pre-surgery prep with David and as Mark reminds him he needs to take all his meds, David cuts him off to finish Mark's own sentence about the risk of infection and rejection, reminding him good-naturedly that Mark already drilled this into his head. Lexie then asks if he has family coming to care for him and David admits he has no family but that his friends are coming. He's never met them in person but they met online in a chat room for orchid lovers and he gestures to an orchid at the end of the bed that at first I thought was a poor dead plant. He's excited to meet them and show off his new face after his surgery. Izzie then brings over a little plastic device and explains that it will help his lungs after surgery and he should practice on it now. One still-nameless intern has him sit up, take three easy breaths, and blow... into that... Nameless Girl Intern finishes his sentence with a giggle, "Hole." It's totally inappropriate but probably made even worse by Izzie hollering at them to get into the hall right now.
Izzie is in the hall, ripping the interns new ones, when Mark comes out, pointedly closes the door to David's room and then shoos the interns away before asking Izzie what the hell is going on. She's totally over-emotional as she yells about the interns making jokes at the expense of the patient while in the room. George is standing a little ways away and stops to watch the conversation, clearly concerned. Izzie goes off some more but Mark tells her that while the interns were inappropriate, so is her outburst now. He reminds her that this case is his baby and he's spent three years preparing for it. Let's just ignore the fact that we've been watching these characters for less than 2 calendar years and that Mark hasn't even been here that entire time, as well as when we saw him all concerned that people think he just does nose jobs and nothing substantial. At any rate, he doesn't want her emotional life getting in the way and he boots her off the case. Izzie pleads that David needs her there so Mark says she can be there for him before and afterward but not for the surgery. He then warns her that she'd better get whatever is going on under control, and George furrows his brow some more from a little ways away.
