Digimon Adventure

Tai and Agumon return to the Digital World to find Tokomon. Tokomon relays what has happened in the time that they have been gone (which is several weeks in DigiWorld time). He reveals that the entire group has separated and that DemiDevimon has tricked T.K. into becoming his "friend." T.K. realizes DemiDevimon's trickery after Agumon exposes him for a fraud. Tokomon digivolves into Patamon and drives DemiDevimon away.
