This episode of House was painful to watch, with two extremely dramatic plots. First, House is challenged to a deal, where he has to stay off his pain medication for a week to prove that he isn\'t addicted. He manages to complete the week, but with great difficulty; he finally admits that he is addicted. Although he needs the medication for his pain, he decides that this is the way he wants to live, because he\'s still healthy.
Meanwhile, a 16 year old boy, son of a man whose wife died of cancer, fights for his life. This episode is unique, because the mystery of his illness is not discovered until later, and there is controversy about whether House really has a straight mind while he is off his medication. You don\'t find out whether the patient lives or dies until the very end, nor do you have much of an idea.
This episode is one of my personal favorites.
