Despite watching II any number of times, like you, I notice new things during every viewing and speculate about their meaning.

This time around I noticed that when Michael returns to the compound after Havana and during the Nevada winter, he stops in the snow and looks at the little motor car that Tom purchased for Anthony. Then he takes a long look at his bedroom and the formerly broken window glass from the attempted assassination. Then, of course, he takes another long look at Kay sewing. He then goes to Mama to ask about losing his family. All quite poignant.
