Ok. Caim saw very quickly friendly, silly, Mammon just left the building. The facade was gone. He was no silly crazy club goer. With all Greed's usual hype, sometimes it was easy to forget. This was no crowed prince or original sin for nothing. Caim was realizing he just insulted someone very powerful.
His next offer would have to be good to make up for it. Caim had a hard time focusing as the whole world was literal pulled out from under him and he'd crashed to the floor. Caim started to get up as he said, "40%" Caim was greedy himself. He wasn't about to 50/50 after sprear-heading the whole operation himself.
