Has anyone considered in all seriousness that archie isnt danny's dad though, because, Archie and Glenda - Both blonde they produced Ronnie and Roxy (Blonde Children) and now Danny he is Mousy brown, where did that hair color come from?
Whereas We never met Eric did we but we know Grant and Phil were darker - when they had hair lol.
and then there is the possibility she wasnt preg when she left, she could have fell preg after she left archie to someone else, i think it would make for interesting viwing lol
