If William is the villain: He's very powerful among the villains. He's charming, intelligent and flirtatious. He feels attraction towards you, even if he doesn't want to admit outloud or to himself. He likes to tease you, annoy you and make fun of you because you are not able to catch him. If William is the hero: He's very serious about his job and wants to do anything to get the villains locked up. He does still feel something towards you, but doesn't want to admit it.
