I think I've been able to find a catalyst that won't involve "...and another several years later' kind of break within the narrative arc. Because I ... I don't feel like doing that. Perhaps yesterday was my week 2 slump. :P

I also had half an idea about having IDK letters/diary entries from one of my MCs between the chapters, but we'll see. He writes the prologue that way, and IDK, it might not be a bad idea to have his thoughts from the future helping to structure what's going on.
