The thing that makes Vance kinda scary is that he is ambitious and clearly has no morals. That's a dangerous combination. Luckily he has the charisma of a mildewed dishrag. But he's clearly okay with sowing chaos and hate for his own gain.

He's a Redditor that "ascended" by becoming a billionaire vampire's bloodboy. That's pretty a fucking dangerous type to have that close to power.
