That's yet another deleted scene (actually a snippet). In the theatrical version, Tom gets up from the table and says, "Thank you for the dinner and a very pleasant evening. If your car can take me to the airport...Mr. Corleone is a man who needs to hear bad news at once." He then gives him a patented Robert Duvall look. Woltz stares back intently.

In the extra snippet, Tom pauses on the stairway outside the dining room on his way out because he hears a commotion. He looks up and sees a disheveled Janie at the railing, with her mother tugging her back (presumably into Woltz's bedroom).
