Jeremie has perfected his "Teleportation" process, allowing him to send his friends to the location of Xana's supercomputer in the real world to destroy it. He uses it on Aelita and Odd first, sending them to the jungle laboratory containing the supercomputer. As they explore, they find that XANA is constructing cybernetic spiders with the help of a team of possessed scientists. Before they can stop him, however, William manages to sever their connection to the real world, bringing them back to Lyoko in the middle of their mission. In a side story, Yumi is angry with Ulrich because he has forgot her birthday, so Odd promises to get Yumi a present for him because Ulrich has detention.
