7.43 23 minutes In order to defeat XANA, whom they have vastly underestimated, Jeremie plans to design another multi-agent system to combat him. That, however, is still under development. In more immediate matters, Jeremie has figured out how to free William from XANA, but needs to run his program directly from the Ice Replika supercomputer. Meanwhile, William's parents arrive to visit their son, and the strange behavior of his clone concerns them greatly. Back at the Replika, William and two Mantas come to try to sever the translation. However, the Mantas are quickly destroyed by Yumi and Ulrich. William then jumps into the digital void and comes back up with the Kolossus. Jeremie uses some new tricks to stop the Kolossus, allowing Aelita and Odd to reach the supercomputer without worry. However, an army of robotic drones now stationed at the facility complicates matters and they de-translated Odd. With much effort, Aelita is able to run the program to free William before she is de-translated also, but their victory comes at a cost: though William is saved, the Skid is destroyed by the Kolossus with Aelita in it. Fournately, she is devirtualized before the Skidbladnir was totally destroyed. Back on Earth, William is able to take his clone's place, pacifying his concerned parents. Ulrich, meanwhile, has to deal with William's affection for Yumi once more.
