Olivant, I agree and disagree. I, too, don't think that any harm would have come to Frankie's wife or the daughter that we see in the scene at the mall, and that it's their financial well-being that is discussed. However, even though it was "between the brothers", I've always thought that Vincenzo Pentangeli might not be as safe from harm. I believe that's why Frankie brings his brother up in his conversation with Tom.
