House comes to see Shitter, who tells him the "complaint department's across the hall." I'm guessing it's the room with the poster on the door that says "Complaint Department -- take a number" and then has a picture of a grenade with a number flag on the pin. House doesn't get to respond to Shitter's non-witticism because he has to look all contrite. "I'm sorry," he says. He admits that he's somewhere between "arrogant" and "unhinged," but "there's a reason [he] operate[s] that way." Yes, because it amuses us all. "I live in pain," House explains. "Pain that on good days is merely intolerable and on bad ones, it will suck the life force right out of you." Well aren't you the special one, House? Your pain is worse than anyone else's in the whole world and no one can know how you feel. You sound like an angsty teenager, dude. Grow up. If your leg hurts that much, then chop it off. It's not going to get better, it makes you miserable, and a prosthetic leg would probably be more useful to you than what you have now. House continues that it's not an excuse for his actions and he was wrong. Shitter looks at him with all the contempt he can muster and then says "thank you." He's not an idiot though, so he knows House doesn't mean it. House isn't sorry for sticking a thermometer in Shitter's ass or stealing a prescription pad -- he's sorry he got caught. Shitter says he isn't interested in what House says (except for the first episode when he told Cuddy he wanted an apology) -- "all I care about is what you do." He won't tell the DA to drop the charges.

Back at the office, House studies his Vicodin in a cool shot from underneath the glass table that we've been seeing in all the promos for the last three weeks, while Cameron persists in talking about their case. Derek's little violent outburst wasn't caused by an allergic reaction to the medication or a pulmonary embolism, and Cameron's got herself some cool red marks on her neck. By the way, since they ruled out medical reasons for Derek's violent outburst, can we just assume that he strangled Cameron because he doesn't like her? I will. House isn't paying attention to Cameron, so she gets all huffy and says "I'm fine, by the way. Thanks for asking." Um, Cameron? When has House ever cared about your well-being? Seriously, he barely acknowledged the bruise on Chase's face, and he's the one who put it there. Foreman wants to do a CT and an LP on Derek for neurological causes, because that's what Foreman does. House tells him to go ahead; he's got other things to do. The Cottages follow him into the hall to find out what they are. He says he's going upstairs. "To do what?" Foreman asks, baffled. Apparently, upstairs is even more useless than the second and first floors of PPTH. "Rehab," House says right as the elevator doors close. Well, this could be fun.
