Episode Title:
Sabotage.
Episode Description:
When X.A.N.A. sabotages the Supercomputer, weird bugs begin cropping up in Lyoko. With its power rapidly draining, Jeremy needs to repair it before it becomes completely useless. However, he seems to forget about boys' dorm inspection, so Jim forces him to stay behind. Meanwhile, X.A.N.A. possesses vines to trip up the rest of the group, except Aelita. Since the attack keeps draining power from the Supercomputer, with no other choice, Aelita purposefully wipes out the Ice Sector leaving only the Mountain Sector left.
