Episode Title:
The Girl of the Dreams.
Episode Description:
After Jeremy makes another failed attempt to materialize Aelita, a student named Taelia arrives at school that looks exactly like her. Jeremy is convinced that it must be her, but she seems to have no memory of her experiences with the group. The others are not quite as convinced, but Jeremy insists that the materialization process must have caused her to lose her memory, but the others were right. Aelita is still on Lyoko and captured by a Guardian. Meanwhile, X.A.N.A. possesses the samurai armor that Yumi brought to school and uses it to chase Yumi. Jeremy brings Taelia with him to the factory. Odd and Ulrich must free Aelita and deactivate the tower before Yumi is defeated by the possessed samurai armor and Jeremy is taken away by the police.
