Ep 26. Just In Time

After another one of Jeremy's unsuccessful attempts to bring Aelita to life, the virtual, young girl's computer programme bugs up : if she deactivates a tower, she will disappear from Lyokô once and for all ! A race against time starts for Jeremy who must de-bug Aelita's programme before Xana's next attack, or else !. Unfortunately, the super-computer jumps into action, sending destructive ultrasound-waves which make the school building collapse and put Odd's life in grave danger. Ulrich and Yumi join Aelita on Lyokô, but in view of the scale of the attack, they soon realise that Jeremy will not have enough time to solve the problem before the tower must be deactivated. They have no choice but to sacrifice Aelita...
