How much information will we get from Jeremiah's memories?

[Mighara Sovmadhi]

Assuming he remembers all that has happened to him, as seems to be the case as of the end of Linden's arc in AATE, he will remember exactly what the Vizard tried to convince him to do, maybe. What Roger and the Ravers and Kastenessen did together to set in motion the Despiser's ultimate plan, if he had been possessed by a croyel by then and in on the all the machinations. Or maybe one of the first things Roger did with his new hand's power was go and master a croyel to control Jeremiah with. Who knows?--I just think we'll get to know.

Some other suggested revelatory memories: the meaning of each Lego structure.

The first person or entity that Jeremiah met on the other Earth.

Things the croyel "taught" him?

I'm at a loss right now to think of more, though I feel like there are more possibilities.
