Jet's portrayal of ZWJ was quite evil/power-hungry.
Personally, I don’t think ZWJ is easily manipulated into doing evil deeds. Granted, the boy is too nice, but he is not exactly dumb. I don't understand why everyone keeps saying that in order to manipulate him, the girls need to act nice and innocence. Zhuer and ZM certainly didn't fit this description, but he accepted them nonetheless.
