S1, E2: Yoshino brings Marcus and Agumon into DATS headquarters so Agumon can be sent back to the Digital World. Luckily, they manage to escape. Marcus takes Agumon home and tries to keep him hidden from his mom, Sara, and sister, Kristy. But Agumon is hard to keep a secret and they soon find out about him and make him feel right at home. Yoshino shows up to recapture Agumon and erase the family's memory, but Commander Sampson tells her there's a change of plans - Yoshino will now just keep an eye on Marcus and Agumon. Yoshino follows Marcus when he heads to school, toting Agumon along in his Digivice, but a disturbance at Kristy's school sidetracks them all. Someone has broken into the school's animal pens. Yoshino is sure that it was a Digimon. Marcus uses Agumon as bait to attract the rogue Digimon. Sure enough, Dokunemon returns to the schoolyard that very night! Yoshino and Lalamon battle the Digimon but lose. Unable to just standy by, Marcus and Agumon step in and take down Dokunemon themselves. The rogue Digimon is sent back to the Digital World in egg form. Marcus and Agumon decide to offer their services as DATS agents, in part so that Agumon won't have to be sent back to the Digital World, and also because Marcus sees their missions as another way for him to become the Ultimate Fighter. To Yoshino's surprise, Commander Sampson accepts their offer. Meanwhile, in another part of the world, Thomas H. Norstein and his Digimon, Gaomon are flying back home.
