Just before Fredo's boathouse outburst, when Michael, Tom and Neri are discussing how Pentangeli is alive, I reckon Tom says gleefully! payback time!!
“No way we can get to him. If we don't it's up to five counts of perjury†"Fredo says he doesn't know anything I believe him" “Roth played this one beautifullyâ€
I reckon he is thinking I am gonna take over! I am gonna be the Don!!
