I can't help but wonder if the creators of this show would entertain the notion of extrapolation where Arthur does return..
After all, that's pretty much the gist of it right? Merlin is servant of Arthur and Arthur is destined to eventually return.
So, I wonder if maybe .. a post - apocalyptic war happened and a new Arthur would be destined to bring back the fractured humanity. It would be the same Merlin.. A re-incarnated Arthur .. and then.. everything else can be totally left to the writers imagination.
