Code Lyoko

After Jeremie fails zet again to materialize Aelita, a student Taelia arrives at school that looks exactly like her. Jeremie is convinced that it must be her. The others aren't quite as convinced, but Jeremie insists that the materialization process must have caused her to lose her memory. X.A.N.A. possesses the samurai armor that Yumi brought to school and sets it on the group to chase them.
