If it is indeed the Apostate, I am curious as to what his long term game is. He himself cannot exist in the Parodyverse as long as Visionary is around. So how does he plan on removing the possibly fake man as an obstacle? Is the goal of removing all those different laws and rules him attempting to find the one that is responsible for Vizh being Vizh? Is he cutting off Visionary from his greatest super power: the many allies he can call upon, before sending someone to kill him? I even thought perhaps this might be a way to try and goad Vizh into offing himself; the Apostate tells him in exchange for his suicide he will return the Parodyverse to normal so that it has a fighting chance against him when he manifests. The last one, while a bit of a stretch, would be an especially nasty way to target Visionary, since so many of the people he loves are the extraordinary types that would no longer exist in a normal world while he, who is (possibly) ordinary, would carry on.

Or maybe I'm thinking too much into this. Guess we'll find out soon.
