House stops caring about his shooter when he realizes something else: his surgery was messed up somehow. He says this while tinkering with the only thing he kept himself connected to: his morphine drip. Cuddy tells him to stop upping his dosage, but House says that he isn't -- he's lowering it. And the effects can apparently be felt instantly, as while his belly and neck hurt a lot, his leg doesn't hurt at all. Cuddy is amazed and pleased, but House isn't. Surgery for gunshots shouldn't alleviate leg pain like this. Something must have gone wrong. "Enjoy the mistake," Cuddy says. House won't, because while the leg pain eraser is a good thing, there are sure to be other side effects that might not be so pleasant for anyone except we, the viewers.
House is forced back to the ICU, where he stands over his shooter with a key that he inserts into what looks like the guy's morphine pump so he can lower the dosage and wake the guy with pain. He can do this because there's no one watching or guarding the attempted murderer. "Why did you try to kill me?" House asks the guy when he wakes up. Shooter says that he didn't -- he strategically shot House in non-lethal places so that House would live and suffer. The only person suffering right now is the shooter, as House removes his morphine connection entirely, and the guy starts moaning in pain and sounding like a total wimp about it, too.
While Chase is trying to biopsy Harpo's lymph node, his tongue swells up so much that he can't breathe anymore. They have to give him a fun tracheotomy.
The Cottages gather around House's bedside with this news as well as House's own medical records, which he apparently requested. Cameron whispers that she shouldn't be giving these to the patient, and then has to say that she's whispering because Shooter McGavin over there is sleeping and she wants to respect his peaceful slumber. Chase's eye roll is amazing at her remarks. House raps Shooter's bedside with his cane to wake him up so he can watch House save a life and be totally amazing. House tells them to give Harpo an LP, as Chase points out that the risks of doing it with the intercranial pressure are no longer outweighed by the benefits now that Harpo has a hole in his throat. House is surprised to find himself agreeing with this.
House and Shooter McGavin spend some quality time in the ICU. It's nighttime, so Shooter asks House whether he wants a bedtime story. House doesn't like it when people talk to him at the best of times, so it's no surprise here that he doesn't want to hear anything from Shooter now. Shooter doesn't care about this and continues: his wife went to House with a mysterious illness. In the process of diagnosing and curing her, House found out that Shooter was having an affair, because all married people on this show cheat on their spouses. This ended up having nothing to do with his wife's illness, but House told her about the affair anyway. And then she killed herself. Shooter McGavin throws House all these sad faces when he tells him, as if it's House's fault that his wife is...er, sorry, was the World's Worst Receiver of Bad News. Meanwhile, anyone who managed to pay attention to the pre-credits sequence in the middle of all the action and excitement will remember that Shooter didn't even know who House was and also said that he, not his wife, was House's patient.
