Mads working on one of Desi's places legal could certainly be a form of connection between them. As for the illegal side of things? He'd work with him, but he has a strict policy that dealings go down outside of Boston, and he wont allow a smuggling route through Boston. but he'd let a smuggling route skirt the city. But that can all be stuff they talk about IC. ^_^
Though Desi will be curious why an Atlanta Boss is hanging around Boston. lol
