@summers i think it matters in this story. Since I am pretty sure a non reincarnated Roxanne would be:
A die early like her bother
B grow up severely twisted like all her other siblings.
Currently she’s putting an act in front of all her family members. She has to do that in order to survive, but her empathy hasn’t died off. Sure it’s still an toxic environment to live in, but since she already had a mature mentality it didn’t screw her up as it would if she were to be a kind in body AND mind.
