yeah that would be interesting. I think he would be kinda and sensitieve and loveing and filled with faith - the things that we have been lead to beleve Mary was.

Oddly enough I think Sam would still be obstanant and obsessive and still (when you get down to it) be very "John" in temperment. Mary would ahve always said "Sam you are Just liek your father" and Sam always would have said "I'm nothing like him! I hate him!"

I also think Dean would have been John's favored child and Sam Mary's
