Paternity

S1 E2: When a teen-aged lacrosse player is stricken with an unidentifiable brain disease, House and the team hustle to give his parents answers. Chase breaks the bad news, the kid has MS, but the boy's whacked-out hallucinations disprove the diagnosis and send the team back to square one. As the boy's health deteriorates, House's side-bet on the paternity of the patient infuriates the kid's parents, but may just pay off in spades.
