2x19 - Digimon: Digital Monsters

While Davis and Veemon remain behind, the rest of the DigiDestined infiltrate Ken's base at the Dark Whirlpool. The Dark Whirlpool contains Devimon's data, which Ken uses for Kimeramon, despite being warned about the powers of darkness. T.K. is angry upon discovering this and confronts Ken. Once Ken releases Kimeramon, T.K. escapes with the other DigiDestined and the base's prisoners.
