EPISODIUM
Aelita finds a photo of herself with Franz Hopper at the Hermitage, with a mathematical equation in the background. Jeremie discovers that the program works as a reset feature to Lyoko, something not too helpful but useful nonetheless. Meanwhile, Odd, in an attempt to impress a girl in photography class, inadvertently sends the photo to Sissi, who in turn shows it to her father. He questions the group about it, with Jeremie pointing out that Aelita would obviously be twenty-four by now if she were the one in the photo. They are sentenced to dentention in the library by Jim before any more discussion occurs. Before he can follow up on the matter, Jean-Pierre possessed by XANA. He delivers Aelita to Lyoko, where the Scyphozoa is waiting for her. It takes control of her and tries to force her to walk into the digital sea, but Ulrich and Yumi are there to keep her from doing so.
