Wow! I haven't seen this before. Maybe because I joined the wiki later. Nice thinking! I think it's pretty clever! But we can't be sure. I think that the writers didn't think THAT far on this one (We, as fans make a lot of our own speculations and think beyond limits sometimes). Maybe Nimueh reversed the sterility in some way and Arthur is actually Uther's son... Or maybe it's what you said... We can't know for sure unfortunately... But it is a great theory indeed!
