S1, E4: The Digimon Data Squad is in hot pursuit of a rogue Digimon named Numemon. As usual, Marcus and Thomas are busy following their separate battle plans. When they bungle the assignment, Yoshino and Lalamon have to step in to bring Numemon down – all the way down to his Digi-egg form. Marcus and Thomas blame each other for their problems, and tempers flare. Meanwhile, two burglars break into a bank, and the device they use to override security attracts Drimogemon. The burglars quickly befriend Drimogemon and get the conveniently, drill-nosed Digimon to help them rob an ATM. DATS moves in! Marcus, Agumon, Thomas, and Gaomon battle Drimogemon while Yoshino and Lalamon take care of the burglars. Marcus and Thomas keep getting in each other's way because they can't — or won't — work as a team, so Drimogemon gets away. Commander Sampson takes them to task for their failure, but he remains adamant that Marcus and Thomas remain partners. Thomas asks to use the Digital Dive to go to the Digital World and prevent Drimogemon from returning to interfere in the human world. Sampson thinks that it's too dangerous and refuses the request. Later that evening, Thomas sneaks into DATS headquarters. Defying Sampson’s orders, he activates the Digital Dive and transports himself and Gaomon to the Digital World!
