No Reason
As House and his team are working on the diagnosis of a man with a giant, swollen tongue, the husband of a former patient walks into House's office and shoots him. House continues to treat his patient from his ICU hospital bed with the shooter, who has been shot by hospital security and hand-cuffed to his bed, as his roommate. When the after-effects of the shooting begin to impact House, he starts to question his own ability to diagnose properly. As his patient's body deteriorates, House struggles through his self-doubt and must trust his team to find a way to solve the case.
Moriarty: "You think that the only truth that matters is that truth can be measured. Good intentions don't count. What's in your heart doesn't count. Caring doesn't count. But a man's life can be measured by how many tears are shed when he dies. Just because you can't measure them, just because you don't wanna measure them, doesn't mean it's not real. And even if I'm wrong, you're still miserable. Did you really think that your life's purpose was to sacrifice yourself and get nothing in return? No...you believe that there is no purpose, to anything, even the lives you save you dismiss. You turn the one decent thing in your life and you taint it, strip it of all meaning. You're miserable for nothing...I don't know why you'd wanna live."
House: "Well here's the flaw in your argument. If I enjoy hating life I don't hate life, I enjoy it."
Wilson: "I didn't say it was rational. HIV testing is 99% accurate, which means there are some people who test positive who live with their own impending doom for months or years before finding out everything is okay. Weirdly, most of them don't react with happiness or even anger - they get depressed. Not because they wanted to die but because they've defined themselves by their disease. Suddenly, what made them, them, isn't real."
Jack: "You pretend to buck the system, pretend to be a rebel, claim to hate rules. [We see that House is pretending to sleep throughout this.] But all you do is substitute your own rules for society's. That's a nice, simple rule-tell the blunt, honest truth in the starkest, darkest way. And what will be, will be. What will be, should be. And everyone else is a coward. But you're wrong. Someone cowardly should not call someone an idiot. People aren't tactful or polite just because it's nice. They do it because they've got an ounce of humility. Because they know that they will make mistakes, and they know that their actions have consequences, and they know that those consequences are their fault. Why do you want so badly not to be human, House? [Cameron and Foreman enter and see House looking asleep.] Oh, he's awake"
House: "Here's how life works: you either get to ask for an apology or you get to shoot people. Not both."
House: "Why did you try to kill me?"
Moriarty: "I didn't."
House: "Then the gun thing might have been a mistake."
Moriarty: "I don't care about semantics."
House: "You anti-semantic bastard!"
