As I recall Starchild the 'official' explanation for Dick as Batman II and Bruce Jr. as Robin II was that Alfred was something of a closet novelist, writing up these imaginary stories of Dick as Batman and Bruce's son teaming up to battle the son of the Joker. In those tales Bruce's wife's face was also concealed from the reader's eye, so they were always left guess as to just who won Batman's heart after all.
Well Bill, one never knows, does one?

Still, given the fact that the Batman II tales were penned long before O'Neil and Adams created Ra's and Talia, I tend to lean more toward the former two suspects. But hey, that's me.
