No, it isn't Cuddy.

But TV Line confirms that at least one familiar face is booked for the House series finale, which will air on May 21 and be penned by series creator David Shore: Olivia Wilde as Thirteen.

We last saw the character in October, when House gave Thirteen a heartfelt pink slip in order for the Huntington's patient to live out her remaining days in relaxing happiness.

As for how the series will draw to an end? It looks like we'll get an idea on April 2 when House returns. Watch the preview above to see what we mean and read through our latest House review now.
