Keltham will continue to iron out details for a while, though not so long that his glibness runs out.
He will then stagger off to his bedroom, looking like he is trying to rush everything under time pressure while not even remotely recovered from his Cheliax Adventure.
It's even true. He's not recovered, he is trying to rush. Keltham is very much drawing on real emotions, real horror, real distress, to give the impression he has to give, when he excuses himself he goes to cry real tears.
The part where you could appeal to stress-induced entropy to make sense of his seemingly suboptimal decisions, as if they were random noise requiring no further explanation except his upset-ness and a handful of apparent verbal explanations stitching them into a purported reasoning pattern?
The part where he's apparently just rushing to conclusions out of pain and rage, and ignoring all the obvious thoughts about better meta-level process that a reader would be rolling their eyes and thinking about, if they read a book character like that?
Nobody out of dath ilan would buy it for a minute.
Golarion, hopefully, doesn't know any better.
