Derek and George have just told Mary the news and explained her surgery, and she's trying to absorb the idea that they'll be drilling into her skull. George explains how the surgery works, that there will just be a tiny hole made and that they'll go in with a scope and it will be minimally invasive. She tells them how weird it is to be on the other side of this conversation, and then asks how the three guys are doing. And then her eyes roll back in her head as she has a seizure.
Jacob's surgery is about to kick off when Izzie looks up and sees Ava in scrubs in the gallery, smiling as she watches the surgery. She mutters to Alex, "I always knew you were an ass but seriously? You brought Jane Doe to the gallery? Are you trying to get yourself kicked out of the program?" First two sentences of that admonition and I'm totally with her, but then it comes to a screeching halt, because I don't think Izzie should be one to throw stones about someone possibly getting thrown out of the program for an infraction. Involving a patient. Seriously, give his money away and slap his name on a clinic, and then the patient who proposed to you and whose LVAD wire you cut to try to save his life becomes a distant memory, huh? Alex tells Izzie that Ava wanted to see what he does, and when Izzie reminds him of Lexie, he just says he's a popular guy, at which point they're shut up by Hahn.
The aforementioned Lexie, meanwhile, has gone to Nick's room at his request. She foolishly thinks he might have a medical problem, but he tells her (charmingly, I must admit) that his book is bad, he hates daytime TV, and all of his friends are at work. She reminds him that she's at work too, and they banter a bit, and she agrees to stay, but takes his vitals to make it seem at least a tiny bit legit. Once that's settled, he asks if she wants to help him plot his revenge against his ex-girlfriend, and he explains a plan of luring her there and then showing her the artery. Unless he means the actual artery itself, I don't think a neck scar is quite the level of revenge he's really looking for. Compared to some of the other things we've seen in this hospital, his neck is about as vengeful as a basket of kittens.
