House M.D. Season 5 Episode 16

An intersexual boy has collapsed on the basketball field. His parents have never told him he has both male and female cells and they (that is, the overprotective mother, who seems to be wearing the trousers) don't want the team to tell him either. For Thirteen, withholding the truth from the kid is easier said than done. To everybody's surprise, House acts kind and actually seems to be... happy, which makes everyone think something fishy is going on.
