For my money, one of the best subtle moments in the Trilogy comes in a deleted scene just after Connie's wedding. Vito and Michael are waiting to be driven to Genco's deathbed. Vito says to Michael, "Did your American girlfriend get home alright?" He says this in a disapproving tone--and rolls his eyes momentarily. Wonderful bit of acting by Brando!

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.
