They eventually noticed that the three recruits were gone and began to snoop around the Academy themselves. The group split up and Jack ended up with Toon, Brian, and Water. He suggested that they look for a weapons storage room. They eventually met up with Paper, Rob, and Zon and compared notes, but neither group had learned much.
Later, Jack helped fight Vilgax's soldiers. He also questioned Paper on why he was in charge, but eventually agreed. After the recruits discussed their options and made their plan, Jack stayed behind and fought more of Vilgax's soldiers. Eventually, they defeated all the soldiers.
After the fight was over, the Magisters congratulated them on their victory. Lotin arrived at the Academy with the late, and only female recruit, Bink. They all introduced themselves to her and then the Magisters showed the recruits their barracks.
