I'm so happy it's going to be told through dickie, christophers father, so we'll see who ACTUALLY had him killed. also from the trailer it looks like dickie was indeed a mentor to tony, and we can see him chugging that vodka, displaying dickie was in fact a junkie like christopher told him at the bbq in season 6, actually seeing tony, sil, paulie, etc and how they rose up the ranks is going to be very interesting and answer a lot of questions.
