Episode 54 of "House"
s03e08 Whac-A-Mole

Houses newest patient is 18-year-old Jack, brought to the hospital after experiencing a heart attack and massive vomiting. Barely an adult himself, Jack has been the parent to his younger brother and sister since their parents died. After a brief perusal of Jacks file, House thinks hes got the diagnosis, seals it in an envelope and turns the process into a game, challenging Cameron, Foreman and Chase to figure it out on their own. When Jack is given an option that would lead to a possible reprieve from his worsening illness, hes faced with a decision that could break up his little family forever. Meanwhile, in an attempt to extract a confession, Tritter makes it almost impossible for Wilson to practice medicine, driving a friendship-ruining wedge between House and Wilson.
