Others are still trying to kill him for this knowledge but no one is successful. He can be a little demanding, bossy, flirty and playful. But when his serious side takes over, somebody will die. He knows he's good-looking and use it to his advantage from finding prey or wooing someone. He's a possesive and a little obsessive but he's caring and sweet.
