I didn't see any emotion in his face at all! He was totally cold and couldn't even be bothered to tell her to get lost and stay lost.
Correct, but when I first viewed the scene, and saw him make a move toward her, for a very quick millisecond, I sort of thought there was going to be some dialogue between them, and the closing of the door was so dramatic. It was in line with the "Fredo you are nothing to me" speech in the boathouse, but done silently.
