Christa Nolan is an agent in Colonial Intelligence.
She comes to Galactica in order to recruit seven pilots, including Karl Agathon and Kara Thrace, to trap any of Darja Purat's terrorist compatriots in any attempt to rescue Purat. Allegedly, her plan is to dangle Purat in order to lure and capture his cohorts, who have attacked two Colonial targets, as they escort Purat to an undisclosed destination through Colonial space.
However, when Purat's cohorts make their bid to extricate their leader, Nolan seizes the outside distraction they provide to free Purat herself. This being the intention all along as she and Purat are romantically involved (Battlestar Galactica: Season Zero 4), she and Purat escape, with Agathon and Thrace pursuing Nolan's FTL-capable escape ship to one of Sagittaron's outermost moons to meet with Julian DiMarco, an ex-Colonial Fleet admiral wanting to rebel and overthrow the allegedly corrupt Colonial government (Battlestar Galactica: Season Zero 3, 4).
She later kills Sil, Julian DiMarco's wife, after Sil kills one of the rebels and tries to enlist the help of Karl Agathon from Galactica. In his grief, DiMarco attacks Nolan, and later kills both her and Purat after they express their desire to leave (Battlestar Galactica: Season Zero 5, 6).
- Nolan's first name is not revealed until Battlestar Galactica: Season Zero 4.
