Jimmy worked on a cattle ranch in New Mexico. In 1958, he was in a diner talking to his friend Cassie Rice when the Tenth Doctor came in and activated an alien device on display. At that same moment a secret agent walked in and tried to take the device. Jimmy confronted him. Jimmy was arrested with the Doctor and Cassie. He almost had his mind wiped by gas but the Doctor saved him. The three escaped but set off the alarms. Jimmy's grandfather was Night Eagle. Jimmy had a habit of calling the Doctor "Doc," which the Doctor found annoying. (TV: Dreamland)
