This is why I think Little Carmine will be back. With Leotardo in poor health and Johnny Sac in prison for 15 years, he has a golden opportunity to take New York again. A war with him could start if he finds out that Tony was behind the Rusty hit, Rusty was one of his "best friends" as he says in season 6. As for certain character betraying Tony....I say Patsy, he is very sour over his brother "Philly Spoons" being whacked in season two, and he detested his "protege" Christopher when he was passed over by him for a vacant Capo spot in season four. Should be an interesting season.
