She and the others needed Coop's assistance in fighting the Kurdock, so Jamie fooled her into taking him instead.

After Jamie appears to defeat Kurdock, Nova and the other cadets hold a celebration on Jamie's honor. Just then Coop and Kiva arrived looking for Jamie. Not aware of what is going on, Nova attempted to defend Jamie from what she assumed was a threat. Once the truth was revealed that Jamie was an impostor. Nova angrily insisted that Coop and the others get him off their planet. In the end, the Ultra Cadets were attacked by the Kurdock, but it's unknown if she survived, she apparently did survived luckily.
