Ep 14. Frontier

Following a heated discussion with Aelita, Jeremy decides that he has to go to Lyokô in person to meet his friend and ask her to forgive him... Yumi is not too keen on the idea as Jeremy is the only member of the group to perfectly master the super-computer's technology. Her fears are confirmed when she hits the wrong key, trapping Jeremy somewhere between the real world and the virtual universe. Part of the scanner's memory has been lost stopping anyone else from transferring onto Look. While on the run from the creatures XANA has sent to get her, Aelita works on freeing Jeremy. Meanwhile, Yumi, Ulrich and Odd try and find a way to free up some memory so they can get to the virtual universe...
