In my opinion, he is a Cailleach-like characer, who comes, warns and leaves-only he was probably not summoned by Morgana. His eyes and the way he talks about Arthur's bane-he could be a druid that telepathetically called Merlin in order to let him know that. At least that's my current theory...we'll see on Saturday :D
