During the wedding reception scene, Michael introduces Tom to Kay as Tom Hagen. I suppose that's to also introduce Tom as a step-sibling for the audience that didn't read the novel. But Tom follows up by telling Michael that "your father" has been asking for you. Then in the meeting after Vito is shot, Tom uses the phrase again by telling Sonny If "your father dies ...". In both scenes, why does Tom not say "Pop" or use some similar synonym?
I also noticed that Oli...doesn't seem he would use that phrase if he grew up as Sonny's "brother."
"Now, that plane goes to Miami." "That's right. That's where I want it met."
