User blog:Uncleho/Perhaps this is how Arthur learns of Merlin's magic?

I was just thinking--what if the only way to cure Gwen of thinking that Arthur is her enemy is through magic. Perhaps Arthur learns of Gwen being under Morgana's spell, and Merlin steps in and helps? Perhaps that would make Arthur feel less betrayed by Merlin when he finds out he has magic. Just a thought. What do you think?
