One thing that I don't get in Godfather 2 is at the very end of the movie (where after the seen of the Family uniting for Vito's surpise birthday), the flim then quickly shows the seen of the Young Vito with the young Michael,(a small child) on a train waving good-bye. I don't get this small clip. Why does Coppola feel that he needs to include this small clip?? What is its signifance? Also, where are Vito and Michael leaving and where are they going?? I know somebody's got an answer to this...
