That's very true about connecting the dots :P I've never realized it but a lot of things are often left for fans to speculate, I suppose that's one of the great things about this show... The mystery. But yeah, I agree and that's what I've been saying as well, I think they'd level headed. They both could only be killed by one weapon. Maybe if there was some sort of face off we'd find out but that's never going to happen.
