Dr. Remy "Thirteen" Hadley

She arrives as one of dozens of candidates competing for a spot on House's team, known only by a number before she earns a name. Guarded and private, she reveals almost nothing about herself, answering personal questions with cool deflection while proving sharp, unflinching in the exam room, and drawn to the hardest cases.

The show teases her out slowly, letting her silence become its own kind of character work, and Olivia Wilde plays that reticence as strength rather than mystery for its own sake. Thirteen watches more than she speaks, and when she finally does act, it lands harder for the withholding that came before it.
