Since there have been several thread lately regarding Tom's position in the family, here's another scene to ponder. For being in an important position in the family (not yet consigliere) Tom makes a less than savvy statement regarding Carlo's future in the family.
TOM
......Now your new son-in-law; give him something important?
VITO CORLEONE
Never. Give him a living, but never discuss the Family business with him. What else?
BTW, I never took the "give him something important" as a question. To me it sounded more like a statement that he wanted confirmed. Regardless, for an up-and-comer in the family, Tom is not in synch with the Don's position. I always thought this dialogue did not have continuity with the character or the situation. For being such a smart guy, why would he ask such a dumb question?
