Ep 23. Attack of the Zombies

XANA uses Kiwi to spread a virus which turns people into zombies. The zombies are all obsessed with doing our heroes in. The Academy becomes the scene for a real-life horror movie in which the character's true personalities are revealed. Jeremy and Aelita are stuck inside the cafeteria, as much by the zombies as by William (who takes his role of protecting his fellow pupils a little too seriously). They must escape and get to the factory and deactivate the tower before it's too late!
