Code Lyoko

Jeremie decides to teach Odd, Ulrich, and Yumi how to use the supercomputer in case he or Aelita are unable to, being XANA's favorite target. During the lesson, Jeremie is attacked by one of XANA's polymorphic clones, leaving the others to operate the supercomputer without help. Aelita is at the final audition with the Subdigitals, competing against two other candidates, and thus cannot be contacted. To make matters worse, the clone heads for her after dealing with Jeremie. Using what they learned from Jeremie, the others are able to rescue Aelita and deactivate the tower without his help. Aelita is also chosen as the winner of the audition despite her walking out on them.
