Jai was an Imperial Cadet at the Imperial Academy on Lothal, training to become a Stormtrooper. While at the Academy, he becomes good friends with Zare Leonis and Ezra Bridger who was undercover as Dev Morgan.
After Ezra succeeds in sneaking into Imperial Headquarters to steal an Imperial encoder, he over heard that The Inquisitor intended to take Kell prisoner. Bridger, with the help of Zare Leonis, rescues Kell, and the three hijack an AT-DP Walker to fight their way out of the Academy. The rebels then return him to his mother and they both went into hiding from the Empire.
