She's cold, calculating, highly intellectual, has a very dark point of view, very cynical, heavily individualistic in a way that borderlines on antisocial, most relationships are meant only to be temporary, holds everyone at arms length, has like two massive blind spots which is the only thing that clouds her intelligence, can and will make friends with the enemy for survival, has turned on allies for survival, keeps everything under lock and key, the only person she's truly nice to is her own son. Need I explain further? Not to mention, she is obsessed with knowledge and will torture to get the facts. And her views are as stubborn as they come, there's no changing her mind.
