You know I examine the trailer just to see if maybe I'm wrong and Gwen and Arthur really do have chemistry....I'm right they do not. I believe a lot of people are fans of them simply because they can't be together...they see themselves as Gwen and they writers are telling them this is who you're suppose to like. But us Merthur fans go where they chemistry is which is Merlin and Arthur, I don't simply like them cause they're male and hot although that doesn't hurt :)
