Jeremy manages to develop a program that will allow the gang to hack Tyron's surveillance system and spy on him, both using video and sound, and potentially speak to Anthea. When the gang go to the Cortex to implement it, all but Aelita are devirtualized by Ninjas when they tip off an unforeseen security system. Aelita opts to stay in the Cortex's core to wait for her mother to appear, asking for a clone to replace her at the school while she's gone, which causes enough problems of its own. In the end, Aelita is able to speak to her mother, convincing her that she is alive before she, too, is devirtualized by Ninjas. The experience initially leaves her feeling very sad, but after Jeremy assures her that Anthea got the message, her spirits are rekindled.

Jérémie a trouvé un moyen de pirater le système vidéo du labo de Tyron. Aelita s'en réjouit: elle va pouvoir entrer en contact avec sa mère. Alors que les Lyoko-Guerriers le testent au Cortex, ils se font repérer par Tyron. Les Ninjas de ce dernier les dévirtualisent en un instant, sauf Aelita, qui décide de rester. Aelita est formelle : elle doit rester sur le Cortex pour attendre un quelconque signe de sa mère...

Jeremy logra desarrollar un programa que permitirá a la pandilla piratear el sistema de vigilancia de Tyron y espiarlo para hablar con Anthea. Cuando la pandilla va al Cortex para implementarlo, todos menos Aelita son desvirtualizados por Ninjas.
