Home Away From Home

Home away from Home is the twenty-first episode of both Digimon Adventure and the Digimon anime series.

Summary
After defeating Etemon, Tai and and the now de-digivolved Koromon find themselves back in the normal world, but Tai can't quite believe it. Anyhow, he heads home to investigate, finding his younger sister Kari, who somehow instantly recognises Koromon, claiming she's seen him before. As Tai begins to settle back into his home world, he sees a news report about freak weather around the globe, and thinks he's seeing Digimon on the screen. Kari quickly assures him he is not just seeing things, and at that moment, Tai's digivice starts acting up. Izzy's face is then seen on a nearby computer screen, warning Tai not to come back to the digital world. Before Tai can get things straight, Izzy disappears, and Tai is left without a clue of what to do. Time passes, and just before Tai loses his temper, the ground shakes, and Tyranamon is seen outside, firing at a nearby building. Tai decides to follow these mysteriously appearing Digimon, and during a fight if what seemed to be Ogremon, Koromon digivolves, causing a rift to open in the sky. Tai and Agumon are pulled into the rift back into digiworld, leaving Kari behind.
