The Prisoner of the Pyramid

'''Izzy receives a call for help from within Etemon's pyramid base, and so the group decide to investigate. Along the way, Izzy makes an interesting discovery about the digital world.'''

Synopsis
After T.K. finds the Crest of Hope, Sora is the only one without her crest. But soon after, Izzy receives a message on his laptop from an imprisoned Digimon who claims to know where Sora's crest is. So, the group set off for the pyramid where the Digimon is kept. Along the way, Izzy reveals that the world they are in is in fact made up of digital substance (?) from the real world. Eventually, the group are inside the pyramid, and after finding their way through various barriers and firewalls (which Tai confidently passes through, as he believes he cannot be harmed in this digital world), they find the captured Digimon, Datamon. He is released, but not before Etemon appears. During a battle with Etemon, Datamon escapes, taking Sora and Biyomon with him. He escapes through another firewall, and Tai follows, though when he realises that his life in this world is in as much danger as in the real world, he panics and freezes in front of the firewall, letting Datamon get away. The group manage to escape Etemon, where they try to think where they went wrong.
