Matt and Tai arrive back in time to drive out the Black Gears inside Leomon. The rest meet up, and start their way to fight Devimon. However even in all their Digivolved forms, the Digimon find they aren't powerful enough to defeat him. He turns his attention to TK, but Patamon intervenes. Digivolving to Angemon, Patamon stops and destroys Devimon using all his power, and brings File Island together again.
