my very bold theory is the Kynthia-shaped Absence-thing? is Lucine's "Aika" (i think im spelling that right??). or y'know how Apollo has a Kynthia-AI?? this thing is Kythnia's mama's "AI of Kynthia"
except make it something Lucine shunned and hid (...kinda like how Apollo has been hiding Aika, except Lucine is worse), resulting in this fake-Kynthia having this Nowhere King from Centaur World-like descent into villainy based on self-hatred. but whereas the Nowhere King took that self-hatred with a silently murderous contempt, this villainy-journey-of-self-hatred would be jokey. and also feature murderous contempt. but also making gags about it. like. when youd make jokes about wanting to kill yourself while suicidal, and gallows-humor-style laugh. being a silly goof in a dark way is what vibe i personally have gotten from the sketches of this not-Kynthia being
anyway, that's my theory based on such little teeny amounts of evidence. and by that i mean, basically no evidence. but it's the feeling im picking up on lol
