some bad ass duo that gets cash and takes names. the brains and brawn. your guy is the brains, d'angelo is the brawns. a lot of the back history can depend on where you put him in the family/what his backstory is, but i was figuring they've worked together for 7 years or so. as a team, they're big earners for the family but since danny is a soldato it mostly just goes right up the chain through your guy to the don. more blue collar crime stuff, robbery of trucks full of swag coming from o'hare, shaking down unions, some drug running and providing protection to businesses that pay them. we can add/delete anything from that list but it's just what i'm going off in my mind. your guy obviously has the final sa since he's capo of the area - d'angelo just works under him. he went to prison for the last two years, but he just got out and is back to work under the northside capo.
