- Straight To Heart
E1Straight To HeartAfter another three-week vacation, the group is still looking for a way to fight X.A.N.A.. X.A.N.A., meanwhile, is trying to destroy Lyoko, preventing them from doing just that. He does so by targeting the core, which contains the code that maintains the virtual world. In a side story, Odd blackmails Jim into asking Principal Delmas to make Odd have the same classes as his friends. Additionally, Yumi decides against having a relationship with Ulrich and decides it would be better if they were just friends. While defending the core, Aelita is suddenly devirtualized by the enemy. However, she still ends up back in the scanners and Jeremy realizes that this is because Aelita is fully human, just like the rest of the group, so she does not need Code: Earth anymore to be materialized on Earth. - Lyoko Minus One
E2Lyoko Minus OneDuring a field trip with the rest of her 10th grade class, Yumi finds herself facing off against the students, teachers, and bus driver, all of whom Xana has possessed. At the same time, Xana plans to get rid of Lyoko through an alternate means: destroying each sector one at a time. To this end, he uses the Scyphozoa to possess Aelita and enter Code:XANA into the way tower, wiping out The Forest Sector, realized by Jeremie. - False Lead

E5AelitaAelita gets mad at Jeremie and she and Odd go into Lyoko without telling anybody, which causes problems. On lyoko, Xana creates a diversion to get everybody to deactivate the tower in The Mountain Sector while the monsters (mostly Mantas and Creepers) worked on destroying the core of Lyoko. Jeremie and Aelita find a strand of DNA that belongs to Franz Hopper, indicating he may be still alive. - The Secret
E7The SecretAfter an angry Yumi chastises and rejects him, a bitter William sets out to uncover what she and her friends are hiding from the rest of the world.

E9SabotageWhen Xana sabotages the supercomputer, weird bugs begin cropping up in Lyoko. With its power rapidly draining, Jeremie needs to repair it before it becomes completely useless. However, he seems to forget about boys' dorm inspection, so Jim forces him to stay behind. Meanwhile, Xana possesses vines to trip up the rest of the group, except Aelita. Since the attack keeps draining power from the supercomputer, Aelita purposefully wipes out The Ice Sector leaving The Mountain Sector left. - Nobody in Particular
E10Nobody in ParticularDuring a test to materialize Ulrich directly into Sector 5, his mind and body become separated, leaving Ulrich's body trapped on Lyoko and his spirit stuck on Earth. What's worse, Xana possesses Ulrich's body and uses it to attack the core. Meanwhile, Susan, disappointed with Ulrich's bad grades, tries to place him in remedial classes. - Triple Trouble

To cheer him up, Jeremie decides to give his friend the power of teleportation. Everything seems to be going okay with the new ability until a bug in the program causes Odd to literally triplicate.
