The season-one House M.D. episode built around three patient stories is titled “Three Stories.”
It is the 21st episode of the first season and uses a teaching-session structure. House presents three diagnostic cases to medical students, gradually revealing that one story is connected to his own past and leg injury.
The episode was praised for its unusual narrative design, which moves between different cases and time periods rather than following a single straightforward patient visit. It also gives viewers important background about House's pain and limp.
A common mix-up is “One Day, One Room,” another memorable season-one episode. “Three Stories” is the episode specifically organized around three diagnostic narratives and House's lecture to students.
