After the children regroup, they are attacked by Leomon, who has fallen under the control of a Black Gear, and Ogremon. After escaping, the children and their Digimon find a mansion to stay for the night, which they discover to be an illusion created by Devimon. Devimon separates the children by breaking up File Island, and when Tai's Digivice frees Leomon from the Black Gear, Leomon sacrifices himself to allow him to escape.
