To be honest, I hope she is going to amass damning shit against her "Family" too. They mentioned she has no way to feel emotion, but she enjoys the process of torture or fucking with people. Like have the father play along with her, and let her do her thing, and then after everyone pays their due, she also fucks his entire life up by framing all of the shit that happened on him manipulating and forcing a poor young girl to do as she was told, or else he'd kill her.
It wouldn't even be that much of a lie either, and would make for a fun chaotic ending.
