Code Lyoko
S04E13 Lab Rat
Jeremie has successfully fine-tuned his "Teleportation" method, enabling him to transport his friends to the site of XANA's supercomputer in the real world to obliterate it. He first sends Aelita and Odd to the jungle lab where the supercomputer is hidden. While investigating, they discover that XANA is creating cybernetic spiders with the aid of a group of possessed scientists. Just as they're about to intervene, William cuts off their link to the real world, pulling them back to Lyoko mid-mission. Meanwhile, Yumi is upset with Ulrich for forgetting her birthday, prompting Odd to vow to get her a gift on Ulrich's behalf since he's in detention.
