s02e19 House vs. God

When 15-year-old faith healer, Boyd, is admitted and claims he can talk to God, House takes the case. House thinks the kid is a clever con untill the boy touches one of Wilson's cancer patients and causes her cancer to go into remission. Boyd refuses surgery on his brain because he believes it will take away his healing power, but as his condition begins to deteriorate and the condition of Wilson's cancer patient improves, House and his team must confront their own feelings about faith and God. Meanwhile, tension is still in the air between Cameron and Foreman after she accused him of stealing her idea for the medical article he had published.
