>>211921175House trying to keep his leg is stupid. Only way he was even able to 'tolerate' the agony was by inducing a chemical coma, which has just about a thousand risks/mortality increases for a healthy human being, let alone one who is also a heavy drug user (even before the vicodin).
It WAS a stupid fucking move, regardless of the fact that his girlfriend went over his head the second he passed out, and House knows it, even if he is in constant agony as a result. He knows it was his pride and the pain talking.
