In House M.D., what nickname is given to Dr. Remy Hadley?

Dr. Remy Hadley is nicknamed “Thirteen” in House M.D.

Olivia Wilde played Hadley, who becomes a member of House’s diagnostic team. The nickname comes from her numbered position during the selection process for new team members in the fourth season. House and the other doctors commonly use “Thirteen” instead of her surname.

The character’s medical and personal stories become important to the series. Hadley carries the Huntington’s disease gene, and the uncertainty surrounding whether she will develop the disease affects her choices, relationships, and views about medical testing.

“Thirteen” is not her first name and is not the name of a medical specialty. It is a nickname created by the team-selection storyline. Her given name is Remy, and her surname is Hadley. This distinction matters because the show frequently uses the nickname in dialogue and episode descriptions.
