In House, M.D., which actress plays Remy “Thirteen” Hadley?

In House, M.D., Olivia Wilde plays Remy “Thirteen” Hadley.

Thirteen becomes a member of House’s diagnostic team after the selection process in the fourth season.

Wilde played Thirteen as a recurring and main cast member across several seasons.
