My issue here is that the "JL confrontation" updates all seem to conform to the standards of shitty SI fanfic - it's Harriezer from Harry Potter and the Methods of Rationality chastising Dumbledore and winning because Dumbledore isn't allowed to say anything intelligent, just stand there and produce arguments tailor-made for the SI to rip apart. The whole situation is so heavily weighted to make the SI look like the only person capable of sapient thought that it obliterates the very idea of Watsonian reasoning: I can't reason out its existence without ascribing it to the author instead of the characters.
Why is this happening? Young Justice was a mostly-awful show that completely failed to acknowledge the seriousness of the Nabu situation in its narrative. Then Zoat copypasted it into WTR, and now he's just spinning his wheels because he can't think of a reasonable explanation for how it could happen in a world where the JL aren't retarded. At this point, I think his plan is to just hustle Paul off of Earth-16 and try to forget the whole thing - after all, it'll be the 2020s before he ever comes back here, so the audience will move on.
Except, the SI isn't the only one capable of sapient thought here. Which is what I based most of my argument for mind control on.
If the SI was an iconoclast alone challenging the League on a decision and showing them their failings, as the only sane man, that'd be one thing. This is sort of a problem the fic has in other areas, namely tech development, where the SI really is a lone iconoclast, though he does in fact have quite a few people who all share his goals and ideals.
But every non-League member has agreed that Nabu is in the wrong. All of them. Nobody other then the League seem even motivated to try to justify his actions, with the exception of Kilderkin. If Zoat thought the League were making a normal human mistake that requires a particular brand of genius to counter,
this would not happen. If it was just Paul and his buddy John, then maybe. Peanutbutter and Jelly along with Zatanna, well she would be biased to want her father back. But the old Captain Cornwall immediately responds, no this is evil, why would anyone think this is okay? Teth Adom agrees, Siskin agrees, everyone who isn't on the League immediately agrees. So, in universe, according to Zoat's own logic, the Nabu situation is obviously reprehensible. It does not take a particularly clever man to notice, and multiple people from various walks of life all agree. Considering that, how is it that the League all seem fine with Nabu? During the confrontation, you could see Captain Marvel begin to piece together that, oh wait, something really bad happened. He has the wisdom of Solomon, yet couldn't come up with basic thoughts like "Nabu didn't actually let Zatara speak"? It's not that this would be bad writing from Zoat, it's that its inconsistently bad writing. The SI is the beacon of light in the world who can do no wrong, and has to show everyone the way, except that basically everyone already understood that the situation was a mistake on the League's part. The ideas "My SI is the only one who can see the madness here" and "Everyone who sees the situation instantly understands that it's bad and needs to be stopped" don't fit together.
The only other option is that the League is, straight up, evil. Acting in self-interest above morality and only caring that a member of their own was killed - as they don't care about the death of Siskin, so they don't care about people being murdered by their associates in general - would be an evil action. I think someone else in the thread put it as Luthor's fears are all accurate, and they really do need to try and defeat the League ASAP so the world won't be ruled by nonhuman tyrants.
But the idea that the League just made an honest mistake is completely off the table. The entire League making the same mistake in the same way when our sample size of people outside the League is 180 degrees the other way suggests malice somewhere.
also no seriously characters are forgetting relevant information to the case in a manner that consistently makes nabu look better then he truly is, it's mind control, how can that not be mind control
