If Griff is Biff's grandson, how come we never meet Biff's son?

Actually, it's never been established whether Biff has a son. Since we don't know what Griff's last name is, Griff could be the son of Biff's daughter. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
