On the off-chance you wander back to Reddit, the theory is also fairly 'neat' as well in that it actually ties together a number of strings - the old tapestry that seemingly prophecized Mimara, Sarl's aforementioned "bouncing dead", the wherefore and why of Achamian and Mimara even being at Golgotterath, and especially the question of Kellhus' prophethood or divinity.

It turns Kellhus into a true prophet that doubted his own divinity due to his own super-rationality and it turns him, the master puppeteer into a puppet of something he cannot Come Before - the Prime Mover, the God. He becomes an instrument - and everything he did, even those things he thought held little Darkness, were in fact in utter Darkness.

So, for example, I don't know why Kellhus instigated Akka and Mimara's journey to Ishual. Maybe it was to confirm its status. And maybe that's what Kellhus thought. I thought it might have been even a round-about method just to make Akka kneel, to fulfill his own prophecy way back in TTT, but you shot that down. But regardless of what Kellhus' intent was, Baby Kellhus turns it all into God's Plan and Kellhus himself into some sort of divine-will automaton, snared the entire time - hence his own, oblivious prompting of Esmenet to free Kelmomas to kill him.

And what better way for The God to finally convince Kellhus of his Divinity than to kill him and resurrect him?

Which is why I still believe! Your feigned shock does nothing to fool me! Unless it was the Greater Bakker that knew Baby Kellhus was the goal, but the Lesser Bakker balked!
