#A BONES EMPLOYEE GOT ISEKAI'D INTO THE BSD UNIVERSE AND REALLY FUCKING WANTED THAT HAPPY ENDING FOR S5 IN 24 MINUTES COME HELL OR HIGH WATE

Y'all, I think I've figured it out. Operating on the assumption that the finale is indeed an alternate timeline from the manga, then someone could have written on a page of the Book to rewrite reality to lead to the events of the finale sometime during season 5's events. In other words, this would explain the INCONSISTENCIES with things that were established or at least heavily implied/assumed prior and in the manga: Chuuya being a real vampire and not in control, nothing being planned, Dazai giving sincere speeches, Dazai really being shot and saying his "last words", Fyodor's hand not being injured, soukoku not killing Fyodor while in Meursault because they literally couldn't and Dazai needing Sigma to discover Fyodor's secrets because of that, Fukuchi's goal not being one that relied on Fukuzawa being alive since he clearly intended to kill him, etc etc too many more to count

Events and explanations in the finale feeling so contradictory and out of place, and characters feeling so ooc and not acknowledging any discrepancies, makes perfect sense if you consider that, up until a certain point, this was our canon timeline — until someone rewrote the ending of the arc with the Book, starting with Fyodor injuring his hand...! We only have one example of the Book being used to majorly rewrite reality in the manga, and when that happened, the main players — the ADA members — were aware that reality was changed, even though they did have memories of the new rewritten reality. BUT, Nikolai was unaware of this during that scene, and so also were all law enforcement because of the clause written on the page accounting for that, so what if the same thing could happen in this instance, to prevent all our characters in the finale from being aware that things had changed? We literally saw someone writing Nikolai's dialogue for him; imagine someone doing that during Dazai's final speech in the episode, and during all the rest of it! I don't know who this would be, but possibly a mysterious third party who got a hold of a different page from the Book somewhere and wrote things to turn out this way, because they wanted the ADA to win against Fukuchi and Fyodor? Maybe even because... this is the only way they can win?

Remember Atsushi asserting this plan, and how silly and too simple it sounded? What if someone else ended up doing just that, writing their own simple outcome for the ADA to win (as a narrative of course, which is probably why it had to start with the major catalyst of, again, Fyodor injuring his hand)? Additionally, if that's what happened, maybe the ending of the finale is a sort of side effect to the Book being used improperly in this way, leading to a destabilization of the timeline or a mishmash of other timelines into the anime one, leading to the alternate Fukuchi and Akutagawa we see there?
