Lee is in the OR. Chase, of course, is his surgeon. He tells Lee they're going to knock him out to drill the hole, then wake him up so he can blink answers to simple questions while they do the procedure to make sure they haven't cut through anything necessary. With that, Lee is running on the beach with his kids in third person POV. He's having trouble keeping up with them, and as they run off, House runs over to Lee's side. Lee asks him why he's not better now and why God seems to doing some trial and error on him. House says God makes plenty of mistakes, but Lee chalks those up to human errors that he was punishing us for. House points out that he is human. Thus, there will be errors. Lee just wants to know if he'll be okay soon. House doesn't know. Lee's version of House doesn't have a limp or a cane.
Lee's awake in the OR. He answers some easy questions by blinking, but can't answer the third question. Well, he can answer it in his head, but he can't blink out a response one way or the other. Chase tells them to put Lee back out. Uh oh.
When we return from Lee's unconscious OR dream, which this time took the form of a commercial break, we're in regular old third-person POV. The Cottages stand over Lee, who lies in bed with his eyes open, squirting eye drops in to lubricate them since he can no longer blink. Molly asks what happened, and Foreman basically admits that he might have cut a little too close to the nerves that control both eye movement and blinking during the biopsy. Which means Lee can't move anything anymore and has no way to communicate with anyone. They don't even know if Lee's in there anymore; the surgery could have caused brain stem swelling and brain death. Well, that's an incredible fuck-up.
In the hall, House is pissed at Foreman for taking away their only way to communicate with their patient. Foreman concentrates on the positive; the biopsy showed damage to the myelin sheath, so now they've got a new symptom. The Cottages put out some diagnoses, and all of them could be easily proven one way or the other if they could talk to Lee and ask him about other symptoms. But they can't, so that sucks. But wait! Taub has an idea.
Lee gets a bunch of electrodes put around his head as Taub explains that they're going to try to pick up his brain waves to move a cursor on a computer screen. All he has to do is keep thinking "up," and eventually the computer should pick up the pattern and move up when Lee thinks it. We go to a montage of Taub waiting for progress and hopefully putting drops in Lee's eyes. But nothing happens on the cursor front.
