im really terrible at articulating my thoughts but lemme try. ..for me argalia think of angela as lower because she's a machine, but then start to project onto her and tries to think of her as a replacement for his sister, then she grows into her own thing in his mind... but that's not exactly a good thing because he can grow more possesive and weirder towards her. for angela, she's pretty naive so arg would take advantage of that to make her only trusts him. she knows the way he acts towards her is strange but after a lifetime of isolation she would easily succumb to any kind of affection. so if they were to meet early, i think they would be kinda terrible for each other since they would be enabling the other.. also my version of their ending would be: argalia distorts and angela becomes a human, they stay in the library together forever ^^^^^_^
