Code Lyoko - Season 1 - Eps 19: Frontier
Jeremie is now taking his ""Materalize Aelita!"" campaign to levels unknown - quite literally. He virtualizes himself, but there isn't enough memory in the system to complete the transfer, and Jeremie is caught between worlds. It will take more memory than the factory has to complete the transfer back to Earth, and if the crew doesn't hurry, Jeremie will be deleted as an old file! Could this be the final frontier for Jeremie? Will Yumi be able to pick up the slack?
