Megas XLR - Season 2 Episode 8 Terminate Her

The Glorft, disguised as a motorcycle gang thanks to their latest Holo-Camouflages, comes to a rock concert. They're not there for entertainment, however - they want to eliminate Kiva's ancestor, which in turn would cause Kiva to cease to exist, which in turn would mean Megas would stay with the Glorft and never reach Coop, which would in turn doom Earth into extinction. Kiva and Jamie must protect the ancestor until Coop can get to Megas. To make matters worse, it seems that Jamie and has fallen for Kiva's ancestor and she has fallen for him.
