What nickname does House M.D. give Dr. Remy Hadley?

House M.D. gives Dr. Remy Hadley the nickname “Thirteen.” Remy Hadley is a physician who joins House’s diagnostic team, and the nickname comes from the number assigned to her during the team-selection process.

Thirteen is played by Olivia Wilde. The character is an internist with an interest in diagnostic medicine, and her reserved personality and personal history make her one of the show’s most distinctive later team members.

The number is not Remy Hadley’s age, medical specialty, or a reference to the number of diseases she has diagnosed. It is a label that House uses after the applicants receive numbered positions during the selection arc.

The character’s full name is Remy Beauregard Hadley. “Thirteen” became the name most commonly used by House and the other doctors, even though it is a nickname rather than her legal name.
