* The Megatanks get DemotedToExtra in Season 4, though they get a few name-drops outside of their ''two'' physical appearances. But why? Even if they're a StoryBreaker Power for the Replika plotline, it doesn't make sense that they don't even appear often in Lyoko...until you remember that XANA needs to capture Aelita and throw her in the Digital Sea. The Megatank's [[OneHitKill circular laser]] would devirtualize her before XANA-William could subdue her, hence the increased reliance on the Tarantula as XANA's main attack monster for this season, and the usage of weaker monsters such as Kankrelats or Bloks.

* The ProtagonistCenteredMorality in Season 1 is actually not ''entirely'' out of character when you take into account that the characters are essentially in Middle school - Children, ''especially'' those with developing minds (like say, Middle schoolers) often have centric moralities.

* Franz not making himself known in Season 1 and most of Season 2 makes semi-sense as he was likely keeping his presence unknown from XANA himself within Carthage, a sector Jeremie couldn't even find until "Uncharted Territory." The moment he activated a tower, two Megatanks tried to destroy it outright.
** Additionally, it's likely that his influence over Lyoko grew as the Return Trips doubled the Supercomputer's processing power. Not only did XANA gain power but Franz would as well but was still not as powerful as his own A.I.
* Jeremie forgetting the majority of "XANA Awakens" and how the Lyoko Warriors came together is not unlike how fans began the series with "Teddygodzilla" with the origin story completely glossed over until after Season 2.

* XANA's not as stupid as we think actually - the entire first season, as we find out, is basically spent powering up XANA. By the time the heroes know that they can't simply rely on the ResetButton, he's powerful enough to attack them ''directly'' - whereas the first season, he attacked them ''in''directly. NiceJobBreakingItHero.
* William being rejected in "Fight To The Finish" initially has some sense to it. With this being their last mission, the last thing the Lyoko Warriors need is someone only just freed from XANA himself and potentially being an Achilles Heel that'd give them trouble. If given time to build up an immunity to any future possessions (Scyphozoa not withstanding) like the others, they might've changed their mind of being too cautious but alas...
** However, it should be pointed out that with his sheer power and his new-found maturity, some fans argues that he learned his lesson and could have even saved Franz Hopper if he was virtualized. It remains up to debate whether or not it was a good idea not to virtualize him.
*** The Skid's destruction might've had a role in their hasty decision. The fourth extra Navskid was blatantly meant for William since they'd need all the help they could in destroying the Replikas, taking the fight to XANA itself. Without it, it left them with the Multi-Agent System which in itself was a gamble. All they needed was to start it up and it'd be, "Bye Bye, XANA" while they could leave William to return to his old life without the risk of XANA reclaiming him. They'd all be going back to their old lifestyle anyways so why drag him back into it? Pushing him away was harsh but likely something they felt was for his own good, not counting on even a simple specter.
* In ''Final Round'', William is shown having an ability similar to Ulrich's Super Sprint, even if it's used for only a second. It would be logical for him to have the Super Sprint, since Ulrich is his [[TheRival rival]].
** Heck, in the Social Game, William ''does'' have the Super Sprint as an ability.

* In "Final Round", after being virtualized, William excitedly asked Aelita how she fights on Lyoko. While he's portrayed as annoying, he does make a point: knowing your comrade's strengths allows better teamwork. Sadly, Aelita ignores his questions and he's later brainwashed into becoming XANA's [[TheDragon Dragon]]. On top of that, William is seen training before going to his first mission. In spite of his LeeroyJenkins behavior, [[DumbassHasAPoint a part of him took the fight seriously]].
-->'''William:''' Wow! ''(looks at his {{BFS}})'' That’s some pretty classy gear! And you? ''(refers to Aelita)'' No weapon? You fight with your bare hands? What’s your superpower?\\
'''Aelita:''' This [[NotAGame isn’t a video game]], William. Let me remind you that we have an important mission to accomplish.
* Yumi's status as the DesignatedVictim makes a bit of sense; she's the only one of the group who lives off-campus. So thus, she's an easier target for XANA to pick on. If she goes missing? It's much ''much'' easier to cover since there can't be an easily-fashioned cover story explaining her absence.
* As pointed out in the main page, Lyoko is GratuitousJapanese for "travel." This makes sense when one thinks about it: Franz Hopper created Lyoko and XANA to stop Project Carthage. Lyoko was probably the program he used to let XANA ''travel'' into Carthage, as a sort of bridge to destroy the program. Even after Lyoko was repurposed as a virtual world, XANA's ability to use it as a means of sending spectres out into the real world seem to evoke this.
** Then there's what Lyoko (the code) does when Aelita enters it into a tower: preps the computer to travel back in time.
* Why are there 3 scanners? It's because Franz Hopper intended to not only go to Lyoko with Aelita, but also his wife Anthea too.
* Ulrich, Yumi (her attempted possession wasn't shown on-screen), and Odd are able to resist being possessed. This could be because, when a human is possessed by a specter, [[NighInvulnerability their body becomes virtual]]. Ulrich, Odd, and Yumi can't be possessed by a specter because their bodies are used to being virtual from their trips to and from Lyoko!
* The ProtagonistCenteredMorality in Season 1 is actually not ''entirely'' out of character when you take into account that the characters are essentially in Middle school - Children, ''especially'' those with developing minds (like say, Middle schoolers) often have centric moralities.

* At the end of the Season 4 episode "I'd Rather Not Talk About It", a Jim-centric episode, Jérémie accepts Jim's offer to come to his next boot camps, even if he was unfit for the first one. His friends don't understand why he would go through this tough training again. However, it makes more sense if you take into consideration that: 1. He and Aelita organized this session with Jim so the whole group would become physically better in the real world, in case of a potential XANA attack, and 2. A few episodes earlier, he mentions that XANA knows the Lyoko-Warriors can barely make the Supercomputer work without Jérémie, thus the destructive AI has centered its attacks on the brainy teen. With this in mind, Jérémie likely realized he needs this physical training, as for the moment he's the one in the group least capable of fending off a XANA attack in the real world, and it could help him during future encounters to be a little more trained on the physical side.
* In "Ultimatum," Odd warns XANA that humans can be killed by extreme cold. Well guess XANA's plan is in "Cold War," a mere four episodes later!
* Fridge Humor: Jim's ExpansionPackPast makes less and less sense as time goes on, since the number of careers he could feasibly have done is much smaller than the extensive list he holds... ''unless'' he only spent a few days at each. No wonder he'd [[MemeticMutation rather not talk about it]].
** This also neatly explains why he's a gym teacher, instead of any of the cushier jobs he's mentioned in the past; it's the only job he could hold down for any appreciable length of time. The sheer range of things he does on campus alongside gym teaching may also be a side effect of his history. He can do a few, if not a dozen, other jobs while only paying for one guy.
** As to why few if anyone in the series calls him out for possibly exaggerating or lying about what he's done: because when you are known to have starred in a disco film ''and'' your nephew is a star drummer, you clearly do have enough things in your history that are interesting that it is hard to guess what is actually false and what is true.
* During ''Killer Music'' Ulrich commented that the titular song made by XANA is fairly unoriginal, as if 'made by a machine'. The virus could understand what commonalities were present in popular songs, but not innovate on them to make something truly unique. Now Aelita never had that problem with her own music endeavors. It's a bit of a underplayed foreshadowing to the fact Aelita is human.
* While shipping is and forever shall be controversial, ''Replika'' actually gives a pretty good showing as to why the OfficialCouple is Jeremie x Aelita and not Odd x Aelita: When Jeremie and Aelita get into a spat it is usually because Jeremie is too laser focused on fighting XANA to pick up on Aelita's interests (usually music, sometimes other things). Jeremie is always looking at the wider picture, even if often too widely, and he will near always, if not always, find a way to make it up to Aelita later (for example taking their time from going after a decoy activated tower in ''Aelita'' to let Aelita check for the information she wanted to find in Sector 5, or going to her music events/giving her music sample to the subdigitals ahead of time). Odd meanwhile got into a spat with her over not covering for him playing video games all night and never really apologized to her. They just worked past it under fire. Jeremie as Aelita once said is 'stubborn as a fool', but he's a fool with good intentions. Odd is also a fool, but not with the same intentions.
* The Skidbladnir's design. Aelita sits in the cockpit to control the ship, while the other Lyoko Warriors sit in small pods called "Navskids" which can be jettisoned and piloted remotely in order to fight against enemies in the virtual sea. Thing is, there's only three Lyoko Warriors aside from Aelita, yet there's four Navskids. The show never explicitly says why this is, but most likely Jérémie designed the ship with four Navskids as preparation for the eventuality of William being rescued and rejoining the team. Unfortunately by the time William gets rescued, the Skidbladnir has already been completely destroyed.
* We essentially have three episodes to get a feel for Jeremie's father. The later two have him appear on screen, but the first season had him mentioned in regards to the school Jeremie was at risk of being transferred to. A 'they would not pass up such a thing for him' description that never comes up again. It's never spelled out clearly but it is very likely that the Belpois got wind of Jeremie finally making friends, let alone a ''very'' special friend in Aelita, that kept them from ever pushing the issue. Jeremie would do well enough at Kadic but he wouldn't have friends if he left it.

** Notably the problem on Ms. Hertz's blackboard differs between the real and false Kadics. Odd and Ulrich, despite being sent back in time by the previous mission, wouldn't notice because they are BookDumb. The reason to change it is also fairly obvious: Xana wanted to show off his intellectual superiority. He was going to kill Odd and Ulrich, no reason not to have some gloating in first. Having false Jim make the two do pushups while he watches is just another little means of showing off.

** The reason Yumi's parents are so poorly programmed is because Xana has the least information on stuff outside of Kadic than on it.
** Yumi being able to pick up Xana plots easier is not going to be a one off event: Xana proves in season 2 that he can possess Jeremie and Aelita and those their age are none the wiser. It offers a bit of a explanation for Yumi's designated victim status.
** Why did Xana not know about the events of ''Frontier'', beyond the fact that season 1 was not as tight on exact continuities? Simple, it wasn't Xana's fault that it happened. It was a typing error, and all Xana would know of the event was that the heroes were doing something and, after he established a pattern of what exactly they were doing, acted to stop them because [[EvilIsPetty why not?]].

* Many people complain about the way Aelita just calmly walks inside the towers in many episodes of season 1, many times in situations where some character is about to die in the real world. But it kinda makes sense if you consider the fact that Aelita at the time thought she was an AI, that she had no memories of living on Earth whatsoever, and that probably meant she couldn't exactly grasp the concept of death. From her point of view, she saw her friends getting devirtualized many times, but they would always be back the next time. Only in later seasons, when she's living as a human, she starts running like crazy towards the activated towers when XANA lauches an attack that puts people at risk. She's finally understanding what's at risk if she's not quick at stopping the attacks.
* There is a visible uptick in plots in later seasons about grade problems for the Lyoko Warriors, a problem that would not have existed in season 1. Many of the missed classes and assignments and lack of studying would come from the drop in use of return to the pasts to cover for these absences. Their peak was in Season 3, likely a trailing result from the drop off in time reversions in season 2 in particular, and the fall from said peak came as a similarly delayed reaction to the group being more liberal in using returns to the past after the events of ''The Key''.
* In ''Seeing is Believing'', Jeremie asks the power plant engineer if there's an atomic process for materializing virtual particles in the real world. This, of course, comes off as Jeremie desperate for potential solutions to Aelita's materialization problem. But given the second season reveals that the supercomputer is powered by a uranium battery, Jeremie may have known this at the time and wondered how the nuclear energy fueling the computer could be used to his advantage.
* For North American viewers, the fact that "The Satellite" depicted just about the ''entire'' school body as having cell phones. At the time, you basically had to be pretty rich&privileged to have a cell phone in ''middle school age''. Well, Kadic Academy is presumably a private school - and being a boarding school, it made sense to viewers in 2003-2004 for ''these'' kids to have cell phones.

* Yumi's status as the DesignatedVictim makes a bit of sense; she's the only one who lives off-campus. So thus, she's an easier target for XANA to pick on. If she goes missing? It's much ''much'' easier to cover since there can't be an easily-fashioned cover story explaining her absence.

* According to Wiki/TheOtherWiki, the RTTP has a limit of two days. Now, imagine if a XANA attack lasted for 3 days or more... Hopefully, the Lyoko warriors are able to spam the RTTP.

* Aelita's first materialization at first raises the question, "Where'd she get the clothes?" Then comes the reveal that she's human, and suddenly it makes sense.
* Jérémie said that one's appearance on Lyoko likely corresponds with one's own subconscious desires; Aelita's childhood toy -- an elf named Mr. Puck -- explains her elfin appearance.
** This also makes a bit of sense if one considers everyone else's Lyoko form being based off of childhood toys or desires - badass action heroes or action figures? Makes sense for William and Ulrich. A Geisha doll Yumi's mother probably owned? Makes sense for Yumi. A stuffed animal of some kind? Makes sense for Odd. What would Jeremie's be, that makes it seem so "Ridiculous"?

* When Aelita tells the principal that she's an orphan to protect her cover in the episode "Wrong Exposure", she's not actually lying. Since her father is trapped in the internet and later dies and her mother's whereabouts are unknown, she is an orphan.

* When XANA gained the ability to possess humans, I often wondered why he didn't just take control of a cop and use his gun to mow down the Lyoko Warriors. But the show is set in France where armed cops (and civilians) are much less common than America.
** That question is still fairly valid, actually. As a person that's lived in France I can say that there are sometimes an odd amount of army members patrolling outside of areas such as school grounds from time to time, so XANA should have used those opportunities, but didn't for some reason.

* We essentially have three episodes to get a feel for Jeremie's father. The later two have him appear on screen, but the first season had them mentioned in regards to the school Jeremie was at risk of being transferred to.

Jeremie would do well enough at Kadic but he wouldn't have friends if he left it.

* The William Clone (Muffin II, if the fan nickname ever caught on), being deleted at the end with no apparent remorse. Not to say it wasn't necessary; just changing his DNA would still leave a double or a stranger with an unusual personality roaming the campus. And fixing that would make it hard to shut down Lyoko if he chose to defend it. But it seems strange that Jérémie, Aelita, or even William don't give any thought to a being they created to resemble a person he could never actually become, in the form that Jérémie once thought Aelita was. Not to mention he helped Jérémie protect the supercomputer in "A Lack of Goodwill", either to save his creator (adds a sad note to the horror), save his data (which would mean he had a survival instinct), or to destroy the real William (emphasizing that his whole purpose is to become someone who already exists and is not him). And now for where the horror comes in: Jérémie updated the clone using some of the data used to make XANA's A.I. Emergent Qualities might not matter anymore if his capacity to learn is intact.

** This also neatly explains why he's a gym teacher, instead of any of the cushier jobs he's mentioned in the past; it's the only job he could hold down for any appreciable length of time.
** The sheer range of things he does on campus alongside gym teaching may also be a side effect of his history. He can do a few, if not a dozen, other jobs while only paying for one guy.

* Aelita's first materialization at first raises the question, "Where'd she get the clothes?" Then comes the reveal that she's [[spoiler: human]], and suddenly it makes sense.

While he's portrayed as annoying, he does make a point : knowing your comrade's strengths allows better teamwork. Sadly, Aelita ignores his questions and he's later brainwashed into becoming XANA's [[TheDragon Dragon]]. On top of that, William is seen training before going to his first mission.

---> William : Wow (looks at his {{BFS}})! That’s some pretty classy gear! And you (refers to Aelita)? No weapon? You fight with your bare hands? What’s your superpower?
---> Aelita: This [[NotAGame isn’t a video game]], William. Let me remind you that we have an important mission to accomplish.

[[spoiler:Unfortunately by the time William gets rescued, the Skidbladnir has already been completely destroyed.]]

* In the season 1 episode "Just in Time", Aelita gets deleted after deactivating the tower because of bugs in the system. However, they bring her back by virtualizing a strand of her hair (which Jérémie had successfully materialised at the beginning of the episode), which supposedly contains her entire genetic code. But if that's true, they wouldn't really be bringing back Aelita at all; rather, they'd be making an exact clone of her. Now, at the time, this wouldn't be such a big deal, but when we discover that [[spoiler:she's really human]], this opens up a lot of awkward possibilities...

* We essentially have three episodes to get a feel for Jeremie's father.

* ''Cold War'': there is no way that a sudden, unexpected, very extreme blizzard did not result in deaths. If the Lyoko warriors ever needed a reminder that they can't revive the dead they probably got it after they returned to the past.

*** It has also been suggested that the supercomputer keeps a backlog of everything that happened since it had been turned on in order to do so, therefore it can be assumed that when the return to the past program is implemented the Lyoko Warriors aren't actually capable of remembering but it is the computer that helped them retain their memories when it activated. This brings across a kind of Fridge Horror when you think about the fact that anyone is capable of programming the computer to reinsert there memories, proven to be true in Code Lyoko Evolution.
