Also notice that in the film and the novel, Tom never refers to Vito as "Pop," "Godfather" or "Don Corleone." In fact, he never uses any form of address.
Turnbull, you're a good man. But Tom does refer to Vito as Pop after they all leave his bedroom after telling him the heartbreaking news that Mike killed Sollozzo; Sonny's wants to go after that pimp Tattaglia and Tom counters with "let the smoke clear, Pop can negotiate."
So he did--excellent catch, Montauk! The novel says that Vito told Tom never to forget his own father, even though Tom's father was an alcoholic and left him wandering the streets. Perhaps that's why Tom never called Vito "Pop" to his face.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
