In the novel it's mentioned that it this could have been due to the traumatic event with their father.
But to be honest, it could be that she is autistic + the trauamtic event that effected her strongly. She for sure gives strong autistic behaviour
Oh ok, makes sense
İts actually revealed in the novel that she is autistic and that her condition got worse since she never received proper treatment and also got the father trauma
Oooh that makes so much sense
True. It kinda sticked with me more when he said "but she's not like that" but thinking back, he said this because he wasn't educated about this yet and strongly believed it was all due to the trauma
Is the little sister autistic or is it something else? I don't remember and it's been years
