Ironically enough, Johnny Sacks is dying of lung cancer in prison; Dr gives em 3 months to live. Guy starts smoking again, croaks. So now it's an open market in New York, even more so because one of the main front runners to take the job gets whacked (best scene of the episode).
Looks as if Phil Leotardo is going to start running shit & he wants to start by getting revenge for his brother's death.
