On the other side of the room, Mark makes an incision in Lexie's patient's head but when she tries to hand him the drill, he tells her she's going to be the one to do the holes. She's really not sure but he tells her she'll be the one to save his life, and then he talks her through it. At first she seems alarmingly shaky for someone holding a drill to a person's skull, but she seems to do a good job of it.
Things aren't going so well for Chuck, though -- he starts crashing, and Alex has to start compressions. Bailey notices what's going on and runs over, ordering Chuck not to die as Jackson and Alex get the paddles ready and shock him. Nothing happens, and Bailey gets increasingly desperate as she orders him to come back, even slipping and calling him Charles in a clear callback to the previous Charles who died during a shooting. They shock him again to no avail, and Bailey finally turns her face up to heaven and yells, "You bastard!" and orders the big man upstairs to send Chuck back right now. After a moment, he does, and after she gets a hold of herself, Bailey quietly apologizes for calling him a bastard. See, I really have meant it every time I say that no one messes with Miranda Bailey. Not even God.
Mere seems to be taking her sweet time getting back to surgery, but who can blame her given the abuse she's been taking? She looks pretty beaten down as she walks across the catwalk but then she turns to look out the window and seems confused. She runs downstairs to get the professor's wife and brings her and the others back upstairs to see something -- outside, hundreds of people with candles are standing together and singing. It's incredibly moving, and I got a wee bit teary eyed, as do all of the people standing on the catwalk, watching. A tear runs down Mrs. Sturgeon's face as she tells Mere that they are singing the school's alma mater, but she smiles and is calmer than she's been all day.
As the singing continues, we are treated to a surgery montage, which ends with Teddy thanking Cristina for staying. She tells her protégé that it can't have been an easy decision but Cristina thinks about it for a second and says that actually, it was.
Mere heads back into the OR and of course just then, alarms start to ring because the professor is bleeding too much. Derek works away, clearly worried, but outside at least his patient's wife is doing okay as she cries and watches the people sing.
