Sammy, his kid and leos mom mustve had kids really young, think about it. Sammy and Hazel were about the same age (13) in 1942( if I'm not mistaken). Leo was born in the 90s (around 1995) so that's about 53 years and 13 + 53 is 66. What I'm trying to say is that I find 66 a young age to be a great grandfather. If he were Leo's grandfather I would have believed it more. I'm not saying its not possible because it is very possible. But I think it wouldve been more believeable if sammy was leos grandfather.
