Episode Overview
Title: The Lake Plot: Jeremy, Aelita, Ulrich, and Odd embark on a class field trip to an island in a nearby lake to examine aquatic vegetation. Meanwhile, Yumi stays behind to complete two crucial exams. Jeremy’s anxieties about a possible X.A.N.A. attack come true when the entity unleashes a dangerous electrified sludge that threatens anyone near the water’s edge. Alone, Yumi ventures into Lyoko to confront William. During their battle, she manages to connect with his true self, but X.A.N.A. soon regains control. Just in time, Aelita arrives on Sissi's bike, deactivating the tower while Yumi vows to rescue William one day. They then rewind time, ensuring their classmates are spared from danger.
