Some new information about Olivia Wilde’s first and last (?) episode of the season have been revealed at Ask Ausiello!
Question: Does Thirteen really leave House? If so, when? —Tamar
Ausiello: Next Monday’s episode is Olivia Wilde’s swan song. Of course, if this turns out to be House‘s last season, I have to imagine she’ll put in another appearance in or around the series finale.
