What is the name of House M.D.’s final episode of season one?

“Honeymoon” is the final episode of House M.D.’s first season.

The episode aired on May 24, 2005, and centers on Mark Warner, the new husband of House’s former partner Stacy Warner. Mark becomes ill, bringing House into a medically and emotionally complicated case involving someone connected to his past.

“Honeymoon” is significant because it develops the unresolved relationship between House and Stacy and shows how personal history can affect House’s professional judgment. The medical mystery remains the episode’s framework, but the emotional consequences are equally important to the season’s closing movement.

The title is sometimes mistaken for a romance-focused episode, yet it is also a diagnostic case episode. “Honeymoon” followed “Three Stories,” which aired earlier in the season and won the Primetime Emmy for Outstanding Writing in a Drama Series.
