Code Lyoko - Season 1 - Eps 13: Just in Time
The episode starts with Jeremie still trying to materalize Aelita. He calls the team to the factory to show them his latest development: a strand of her hair that he has materalized into a test tube. Unfortunately, he didn't realize that he pressed one button too many, and thus screwed up Aelita's programming by adding in a whole lot of bugs. The result is that, immediately after she successfully enters the code (LYOKO) into a tower, she will be formatted - as in, deleted. And of course, as Jeremie is trying to literally work out the bugs, Xana attacks by putting out shockwaves to shake things up, putting Odd, the two junior journalists, and Kiwi in danger. But is Jeremie willing to allow Aelita to be deleted in order to save his friends?
