I will give one of the writers credit for Benny, cause I said to my cuz they made it seem like Benny was just a regular felon or criminal. But My cousin pointed out the fact they actually kept him mysterious until now. All they showed was that proctor actually said he was sorry to Benny that he had to keep his distance from him and the family because he didn't want to be associated at work. So they left room for him to be a don.
You're giving them too much credit.
They didn't mean for it to be mysterious. They probably forgot, since characters don't seem to follow their personality when they were introduced.
Just like how all of a sudden now O Dogg is a former cop. They seem to just throw stuff in to go along with a story of a particular episode.
