In the scene where Michael and Fredo are having their drink in Havana, Michael tells Fredo that he'll be assassinated. "Who?" Fredo asks. Michael grunts out "Roth," in a way that suggests to me disgust and regret--as if he's saying, "Why did I ever believe I could do a deal with him."
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.
