Darrow’s future speculation

Hi everyone, long time reader, new time poster.

A thought I had when reading Lightbringer is do you think Darrow was given a more finalised version of the parasite ? The way the “way of stone” seemed to have super focus and almost slowed time and the way the plot line didn’t go anywhere else in the book made me feel it could go in that direction. Lyria is more “human” and refused to lose her memory but Darrow might accept that cost to become of the reaper fully, losing his memory to become a weapon of the republic (a red god of war if you will).

I could be totally of the mark or have missed something but was kind of curious what others thought as so far that plotline seems to have just been dropped.

Thanks !
