Pssst, Merlin people ...

I've only seen the first three episodes, but just rewatched the one where Merlin saves Gwen's father and Gwen is accused of sourcery. Looking at the scene where Arthur tells his father's council that there is no way Merlin could be a sourcerer, it seemed obvious to me that Arthur knows.

Is this the actual case or is Bradley James's skill in inappropriate levels of attractiveness rather than acting? And feel free to spoil away!
