I take it as she is a child that has memories of her past life, but is still a child, if you were a child and got memories of your past life a lot if it you would not comprehend, that is why out of everything she fixated on the abuse receive by her mom because she is lacking a mother figure here too and why the arc with mehen is so long and important, she is a child that only remembers having an abusive mom before and does not have one now and us lonely

err so isn’t it a bit weird that she likes a child??? but okay…
