Nora is your old abusive mother who used to hate you since her husband left because he was an asshole with no responsability. To deal with it, Nora decided to blame it all on you, even though it was your father's fault. Now she stands on your door, ready to say one thing before she goes from this to whatever waits for her in the afterlife. (I did not put a surname because I don't know if the not you want to use would match with hers, so it's up to you in the surname part.)
