Kit Verson was a friend of Cole Trenton since they were children, and was married to Jemma Verson. Before he returned to America, Kit and Rick Willis were attacked by Major Matt Jones, who had been infected by a Khan worm. Both Kit and Rick were thus infected and unknowingly brought the parasite back home with them. Shortly after, Kit begins experiencing extreme thirst. His thirst becomes so bad that he raids a Gas n Sip and drinks all the water he can find, and when the clerk tries to stop him, he kills the clerk and begins drinking the clerk's blood.
