Billy is a former Sabbat, rejecting their views due to his belief in the Buddhist nature of all things. Although tormented by the Beast, as all Brujah are, he seeks a path in the middle way, tolerance and understanding, that brought him to the Camarilla. Still, it seems he was a Paladin in the Sabbat, and quite learned in the arts of war.
He’d be the guy on the left.
