Greed was always attracted to governmental and religious figures. It was foreplay for him to influence them with ultimate greed and avarice. The challenge was in how far they went and the result.
Greed was estranged from his Excess counterparts, Lust and Gluttony. He was a lot more arrogant on his own, spiteful, and could find trouble easily. Pride's newest catch was also under Greed's radar. A pious goverment official? That was a smorgasbord, and an open invitation.
For weeks Greed had become friends with the man without knowing Pride had her claws in. He'd felt some pull, but he hadn't known it was his sister. At least not until he was invited to their home for a lavish dinner.
