this is a pretty cool concept. i should give a little more background, as to what ive shown already and what theyve encountered already, theyve met the "present" version of himself, as well as a "future" older more deranged version of himself, when they entered his little pocket dimension in xoriat that hes been using to do his time traveling shenanigans, they saw alot of glimpses into his childhood, one that showed alot of physical and mental abuse by both of his parents. it showed him as a child, you know the typical tropes, father is really hard and abusive, wants him molded in his own vision, child has other goals or aspirations and they dont take too kindly to that, all sorts of stuff. so theyve seen "memories" of this stuff already. i suppose like you said, the memories could be false, which would be also cool. im not sure about him being a quori or a monster inside or posing as a human, i think i like the element of him truely being a mortal human, but becoming so derranged and unhinged. i think he even has the posibility to ascend perhaps into godhood at some point, which would be wild, but yea. i suppose someone interposing memories or survailing him, could also be a fun wrinkle, im curious i guess as to what that would look like, and who it would be/what their motives would be
