Why wouldnt Castellano sit down with Salvie Testa? Do i even need to say why..serious. NY would of demanded a guy high up in Philly to first contact someone with clout, maybe a capo with the Gambino 's first.
What was Salvie gonna do, knock on Castellano's front door and ask Castellano if he would back him and some other 25 year old guys to take over Philly.
Im sure the FBI bug in Castellano's home would of had a lot of agents laughing at that one.
