S2, E20: Once again, Aelita is plagued by strange visions which seem related to a past she does not recognize. It is in fact one of XANA's schemes! It stimulates our young heroine's memory in order to draw her to Sector 5 where the Scyphoaoa is waiting for her! After a long struggle, our heroes manage to counter XANA's attack. But there's still one question that remains unanswered -- where are these visions coming from?
