About the characters

- Second time Yumi lifts a teammate with her telekinesis.
- Aelita is the first to have countered and smashed a Megatank laser. Her power is becoming more and more surprising.
- Jim worked in the secret service and was a TV cameraman.
- Odd plays Tamagotchi. His is named Jean-Pierre, he enjoys the game a lot.
- Ulrich is devirtualised by one of Odd’s arrows, it’s the third time in the series the heroes devirtualise one another (with 7 “Image Problem” and 55 “Tidal Wave”).
- New appearance of men in black! They’re not the same organisation however as the one who is enemies with Franz, years later, but they do ring a bell. They talk about an ultra-secret organisation, not knowing who they really are and about uranium (like in the Supercomputer’s battery)… Assumptions can therefore be made about the identity of the two men.
The director Sophie Decroisette has confirmed during an interview with Codelyoko.fr that they’re not the same agents linked to Anthea’s disappearance.

About errors

- The factory microphone changes often (wired or wireless).
- The principal’s eyebrows are grey when Jim says Ulrich and Odd should be in the cafeteria.
- The lift door is open before Jim comes to the lab to warn the agent.
- The handle of the principal’s office door is on the right instead of the left when the two agents arrive.
- Odd’s camera changes between the moment when we see it on the desk and when Ulrich looks at it, and when Odd watches the recording.
- The agents’ earbud communicators often change place (left or right ears) and the bald one’s earbud disappears when he rides in the lift with Jim.
- The door to Ulrich and Odd’s room is brown when we see Ulrich take the Tamagotchi then becomes grey when he gives it to Jeremy. The handle is on the left instead of the right.
- When Ulrich watches the security camera footage in the Supercomputer room, he sees the agent shooting lightning at the machine, but it’s not the right agent! We see the Caucasian agent who is actually at the school with Jeremy. We should have seen the bald agent!

About the series

- French title: Fausse piste

- New tactic by XANA to destroy Lyoko: attacking the Supercomputer directly.
- First time we see the effects of the Supercomputer’s gradual destruction on Lyoko.
- First appearance of Megatanks in the Mountain Sector. One of them attacks in a way we’ve never seen before (horizontally)!
- Jeremy’s mobile phone number is 162-432!
- The co-ordinates of the activated tower are 25° west, 72° south!
- When the principal asks Jim what Odd’s dog is doing in his room, he responds that it’s the first he’s seen of it, despite having chased after Kiwi several times and not having the memory erased. He probably said it to cover up for allowing a dog to stay in the dorms, since he never managed to catch the owner or the dog.

About references

- Ulrich: “Oh no, seven years bad luck!”
This is a phrase used often by superstitious people when they break a mirror. The theory of there being bad luck around breaking a mirror has been seen in several different cultures since the mirror was invented, each believing that the mirror can capture part of the soul, and a distorted reflection means corruption of the soul. The seven year timespan comes from the ancient Romans believing the physical body renews itself every seven years, meaning a healthy new soul as well.

- Allusion to anthrax.
It’s a disease that originates in sheep and cattle that can be passed on to humans, causing several severe types of illness or skin irritation.
