Эпизод 10

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