Can anyone tell me what exactly is the deal with Nepthys like what was the whole she isn't the real one. Also if some can explain what the hell is going on with Anubis. Does he resent Seth because of all his crimes and him imprisoning his mother or was it osem specific thing. And what is Anubis's curse that is mentioned??
