At the end of season 1 when Uncle Junior is arrested , the agent said they wanted Johnny Sack but more importantly they wanted Tarese and Mangano . But they never brought up Carmine Lup, and at that time wasnt Johnny just a captain (maybe underboss) but agent never brought up Johnny's boss Carmine Lupertazzi .
It would be cool to see the other boss's Tarese , Mangano, Paglieri at least once maybe at Carmine's funeral or something .
