Countdown

Storyline

Samantha Suarez - Odd's former sweetheart and girlfriend - enrolls at Kadic, and the boy eagerly pursues her. At the same time, he is being pursued by a polymorphic specter, which XANA is able to create due to its new increase in strength and power. The others go to Lyoko to deactivate the tower but are all devirtualized by a giant wall of Bloks. Odd destroys the wall using a scanner eyepiece programmed by Jeremy and deactivates the tower. Meanwhile, Jeremy's computer is set on repairing a corrupted video file recovered from the Cortex. Eventually the task is completed and the gang watch the clip of Franz Hopper, furious at an employee who stole some documents of his. He fires the man and storms out, but the man remains in the room and laughs, calling Franz too naïve. Aelita identifies the man as Professor Tyron though she had never heard of him before.
