Its pretty clear that Paul took a while to make Roy. I mean Roy was already a major earner for years so he could have been made in the first batch when Carlo died. I'm sure Nino proposed him for a while. Its pretty clear Paul looked down on Roy but wanted to keep him around because he was one of the bigger earners in the family and he could take care of hits Paul wanted done(Frank Amato, The eppolitos) After the Westies alliance Roy kind of forced pauls hand.
