Jack attended a different school prior to enrolling at Glasshouse and felt that the move was due to his own shortcomings rather than anything related to his old school. His dad brought him to Glasshouse for his first day, where he began to fidget. He introduced his son to his teacher, Calypso, who suggested that Jack play with a Red Kelpie named Rusty. Upon learning that Rusty was going to play a game of army, and hearing what it involved, Jack initially believed he wouldn't be good at it. However, Rusty soon determined that Jack could perform to his own satisfaction, and to Jack's delight he was invited to participate. Jack greatly enjoyed the game and his new friendship, finding that there were aspects of pretending to be a soldier that he liked.
