History Headscratchers / AssassinationClassroom

* When Koro-Sensei had to punish his students for causing an old man to get hurt on their way to school, he also involved the ones who exactly ''weren't'' involved. He slapped all of them across the face, ''including'' those who were entirely uninvolved in the situation. He not only scolded the uninvolved kids for something their other classmates did, but gave all the innocents an equally cruel ArmorPiercingSlap! Apologies and "equal treatment" be damned, he shouldn't punish or ''harm'' those who aren't included in any sort of incident like that! So why did he?

** Koro-Sense has a maximum recorded speed of Mach 20. That does not necessarily mean that he always uses his top speed.

* Itona went to live with his uncle after [[spoiler: his father ran away]]. How could Shiro take Itona with him then? Was the uncle THAT negligent?

* The ending to chapter 128 is definitely one [[spoiler: Kayano showed not that many, if at all, hints of having those tentacles. While it was hinted she was not in the school last year due to not knowing Karma, she seemed friendly enough with everyone to know them longer than when Koro decided to be a teacher. Why would she only now strike? Because she had time to find all his weaknesses? She could have done it loads of times. Maybe it will make more sense in future chapters. If there was some more then a few pictures of foreshadowing, then it most have been too subtle (or did not fit in) for this troper, and for now it just seems like the author thought of this idea maybe a year before the chapter's release.]]
** You'd be surprised. The earliest hints span back as far as [[spoiler: [[http://microlm.tumblr.com/post/111593001543/regarding-chapter-128 Chapter 29]], when Shiro first appears (along with some other compiled hints observed). There are other instances of her tentacles hiding in plain sight that the fandom has uncovered, one in [[https://40.media.tumblr.com/559e124d44d0ae5e3e727afb0e483814/tumblr_nk7j7b7hQL1rfswm8o1_540.png 31]], one in [[https://40.media.tumblr.com/2c8062290d00084555e66c6cd61b202a/tumblr_nk7ojpT7kt1rfswm8o1_540.jpg 80]], and in Chapter [[https://40.media.tumblr.com/f020b9fc2293f0136dd24b2f86a22be8/tumblr_nkc5r4RsHY1rfswm8o1_540.jpg 124]] and the fandom is still combing the pages if they can find more. Seeing as her point ''was'' to not be suspected and have hidden bloodlust (as Nagisa served as our RedHerring in Shiro's observations, it's less of an unprecedented twist as some would think it is and more like the effective execution of her long-hidden blade. As to why she waited until this time remains unclear however. On the topic of friendships, it might not be so strange that she acts friendly enough with the others because of her pretend(?) personality; it's also unlikely that all of Class E knew each other prior to that year, so it isn't so much a matter of length of time knowing each other.]]

** [[spoiler: The finale shows that eventually, the moons gravity causes the moon to collapse in on itself and resume its original shape, and also have an orbit closer to Earth. The two combined is probably a HandWave to have Earths ecosystems resume some normality.]]

* Couldn't Korosensei [[spoiler: just dig underground to escape the "Shield of Earth" filled with the Anti-Sensei material, which trapped him in for a week]]? That way, he could have [[spoiler: somehow survived, and wouldn't have to be killed by his students to avoid death at the hands of the government's laser? Sugaya could have also made a dummy to make it SEEM like Koro Sensei was killed, throwing the governments of the world off his radar. Koro-Sensei could have then gone off to live for another 90 years, just like the International Space Station's data indicated he would.]]

** Since his true purpose was[[spoiler: to have Koro-sensei acknowledge him,]] he was probably satisfied with just defeating his targets (all assassins who were apparently targeting him rather than the other way around). That is to say "Look at how good an assassin I am, I can beat up all these other assassins!". After all, the students are all considered top-tier assassins partially due to taking down other assassins non-lethally, why shouldn't the same thing apply to him?
* Wait, so are Kayano and Nagisa canon or not?? The epilogue seems to imply [[spoiler: she's pregnant]], but she also says regretfully that Nagisa probably doesn't even think of her. And we get no confirmation one way or the other from Nagisa's perspective. It seems to imply both sides at the same time, so which is it?
** No firm comfirmation one way or the other, though in my head-canon, she's being a [[SecretRelationship bit less than truthful...]]
** Kayano [[spoiler: possibly being pregnant]] doesn't mean that the [[spoiler: other parent]] is Nagisa. It's entirely possible that she's with another guy, it has been seven years since graduation by that point.
** Kayano is now a famous actress, so it's entirely possible [[spoiler: she's concealing her relationship and pregnancy (she's not wearing a ring so she isn't married/public about her marriage) in order to avoid the media catching wind of it/her friends teasing her about it.]] It's left ambiguous on purpose. If you ship them, then they're canon. If you don't, then they aren't, and she's with someone else.
* Wait, I'm confused about something: [[spoiler: If Korosensei WANTED to be killed the whole time to save the Earth, why not just let himself be killed? Why go through all this elaborate set up with the class?]]
** In his own words: "I'm making good on a promise, one I don't take lightly." [[spoiler: He intended to die, but his first priority was looking after class 3-E like he promised. Training them in both academics and assassination made them strong enough to actually kill him while protecting them and preparing them for life, as he promised Aguri.]]
*** I can understand the reasoning behind that, but in that case... Why not [[spoiler:make an agreement with the world governments that he'll let himself be killed after teaching for one year]]? I could even understand if [[spoiler:the governments decided he can't be trusted on that]], but it's strange that he never even ''attempted'' it, especially in a series where the protagonists usually analyze every possible angle of their current problem.
*** Koro-sensei destroying the world in a year is the motivation for the class being trained as assassins. Hence, the government's continued interest in training them through Karasuma, as well as fostering their own desire to grow strong enough to kill him. Being told [[spoiler: I'll just let you kill me at the end of the year]] removes any motivation for anyone in the situation to actually ''try''. Koro-sensei wants his students to grow through attempting to assassinate him, which means that to every involved party he must both look impossible to kill and [[spoiler: unwilling to die.]] Otherwise, everyone would have been just like Terasaka was and not actually put the effort in.

** Kayano [[spoiler: possibly being pregnant]] doesn't mean that the [[spoiler: other parent]] is Nagisa. It's entirely possible that she's with another guy, it has been seven years since graduation by that point

** Also keep in mind that the chairman is a major-league KnightTemplar and {{Jerkass}} who would rather let Koro-sensei ''destroy the planet'' than admit that he was wrong about Class E.
