In the other OR, Hahn is showing Izzie how Jacob's sternum is all cleaned out, which means they're almost done. Mark asks if she doesn't want to stay and watch him work, but Hahn just shuts him down, telling him how offensive he is. He tries to play innocent -- not his strong suit -- but she calls him on it and asks if he gets away with this behavior because of his looks. She's hit a nerve, but explains, "I'm saying, if you were homely you would have lost your job a long time ago." If he were homely, clearly he wouldn't have been hired by Seattle Grace, the Prettiest Hospital of the Northwest, in the first place. He glares at her as a nurse calls out that Hahn is needed in the ambulance bay.
Lexie's still holding on to Nick's neck and asks if he can reach his call button. Unfortunately, when he moves, blood tends to squirt back out between her fingers, so she stops him and asks if he can reach the phone instead. He manages to do so and is able to put it to her ear, and when a nurse picks up, a terrified Lexie stutters that she needs Sloane paged and decides that she's calling this a code blue. Nick puts the phone down but then panics a bit about the fact that a code blue means he's dead. Lexie explains, "I figure we can use all the help we can get." Tyler the scrub nurse (thank you, knowledgeable readers, for telling me his name!) leads a crew in and they get to work immediately.
Bailey's still working on Shane when a pager goes off, and she calls out that she doesn't care who or what it is while Cristina shoots daggers at her over her surgical mask. The nurse tells them it's actually a 911 page for Cristina from Lexie, just as another nurse pokes her head in to the room to tell her that Lexie called a code blue that wasn't a code blue. Cristina is confused, and Bailey tells her to go find out what's up. This surprises Cristina, who after all she's been through thinks Bailey needs her, but Bailey happily tells her that she's fine and adds, "Go kick some intern butt." It seems that from the midst of her own troubles, she can't see that Cristina's rage is taking on a life of its own, and Cristina stomps out of the room.
While the team works around Nick, Lexie's still hanging out holding on to his artery, and he asks her how she's doing. He calls her Dr. Grey but she tells him to call her Lexie. I do think that by the time your fingers are in a guy's neck, you're definitely on a first-name basis. She asks how he's doing and he admits, "I'm kind of freaked out if I'm being honest. Mostly because you look like Carrie at the prom." He's not wrong, and she tells him that they're hanging more blood to give him. Tyler tells her that he's having a hard time finding a vein because they're flaccid. Nick would probably blush if he had the blood left to do it, but still gets bashful and tells him that's not a nice thing to say. Tyler then sticks him and he screams, causing more blood to start squirting just as Cristina comes in. Lexie says that her hand slipped and Nick begs her not to let it happen again. She explains that she called Sloane, and asks about taking Nick to an OR, but Cristina grimly tells her that there isn't one available, just as more blood squirts through her fingers for emphasis. Lexie very calmly tells Tyler (oh, so now they use his name for the first time all season?) to get more blood, and Cristina runs to get Mark. Lexie starts to panic but Cristina orders, "You can do this. You're doing this!"
