About the characters

- Second time Ulrich’s sabre is devirtualised by a Megatank.

About errors

- The manhole cover is brown instead of green.
- When Odd’s listing the powers the others have, he says “you can all make stuff appear” but Aelita is the only one who can do that.
- Emilie’s undershirt sleeves are the same colour as her skin just before Odd goes to the drinks machine.
- The antenna on Odd’s phone is on the left instead of the right.
- The halo of a tower in the Mountains is blue instead of white.
- The door to Odd and Ulrich’s room is brown instead of grey.
- One of the three Odds’ pants are entirely purple during a scene in Jeremy’s room.
- On the factory computer screen, Aelita’s icon is green instead of yellow when we see “Aelita vs Megatank”.
- The doors in the hallway are blue instead of grey when Jim turns to see the second Odd.
- The microphone in the factory is absent when Jeremy explains how to use the teleportation power, it’s in his right ear when he says “Transfer Ulrich” and it changes nonstop (wired or wireless).
- When Odd 2 reads the movie magazine, he singles out Wheelchair Zombie 4. When Odd 1 reads the magazine later, he sees Surfer Zombie 4.

About the series

- French title: Triple sot
- Original English title: Three is an Odd Number

- Jeremy deliberately didn’t reprogram Odd’s Future Flash after it was wiped while he was updating the Supercomputer, saying it was useless.
- First mention of a film: Wheelchair Zombie 4!
- First time a Megatank destroys its partner by accident.
- First time one of the heroes (Ulrich) is run over by a Megatank.
- One of the three Odds reads the same comic as in episode 24 “Ghost Channel”.
- The access code to the lift from the scanner room is 7309.
- The problem Odd starts to have is similar to the cellular degeneration Odd and Yumi experienced in episode 42 “A Fine Mess” and the problem Aelita’s ‘antivirus’ caused in episode 44 “Vertigo”.
- The newspaper stand from episode 35 “The Chips are Down” is in this episode, and the person behind the counter is reading the same magazine as the hospital receptionist in episode 60 “Temporary Insanity”.
- When one of the three Odds is petrified near the science building, Ulrich says a precognitive phrase to Aelita: “You wouldn’t happen to have a pair of wings on you?”; 4 episodes later, she gains wings with her new Lyoko outfit.

About references

- The pose Jim is petrified in is similar to Discobolus, a famous statue from the Roman empire representing an athlete throwing a discus!

- Odd: “Well if Tarzan can do it, so can we, right?”
“Tarzan” is a Disney film based on the books Tarzan of the Apes by Edgar Rice Burroughs. The story tells the tale of a boy who was adopted by apes as a baby when his parents died, and raised as an ape, unaware that there was an entire species that looked like him. In the film version Tarzan is skilled in “tree surfing” and swinging on vines, which he learnt from various other animals in the rainforest.
The cry Odd makes when he jumps off the building towards the trees, and the one Odd 2 makes when he slides down the hose, is very similar to Tarzan’s cry in the film.
