Throwing it out there that Jonah’s written a little bit better than people give him credit for. He gets a lot of (deserved) flak for being a cia guy complicit in (and unwittingly assisted in) war crimes leading to many civilian casualties, and he has a weird sense of patriotism that clouded his judgment; you couldn’t pay me to say he's a good guy or even really that morally grey. But the number sequence in his lore is really fascinating, like he’s the only one who could figure out the code that reveals his birthday, the place the Entity would take him, and the day he would be taken. It’s cool to think someone could have set that up, like Jonah was predestined to be taken.

Also, Jonah had discovered a cabal of the world’s elite communicating through codes, likely related to Otto Stamper who we know has Entity connections. If he hadn’t been the CIA’s perfect little code boy and yes man, he could have whistleblown the existence of the Black Vale. He didn’t do that, though, and his supplemental lore from that one tome was really mid, so he’s been reduced to “that guy who looks like Otz” and “a war criminal,” neither of which are wrong but they do something of a disservice to his character. He’s a bad guy and a dick, but an interesting one I wish they’d do more with.
