House: You asked me how I'd hurt my leg. I had a blood clot, and the muscle was dying. And I had all these doctors telling me I should amputate, and I said no, and they did this... very risky operation. I almost died.
Hanna: But you saved your leg.
House: I wish I hadn't. They cut out a chunk of muscle about the size of my fist, and they left me with this mutilated, useless thing. I'm in pain... every day. It changed me. Made me a harder person. A worse person. And now... now I'm alone.You don't want to be like me.
