I think the whole issue of magic reveal was badly developed in the show. Merlin telling Morgana about his powers would make sense, and would be a more interesting situation, regardless if Morgana turns evil later or she doesn't. Also Morgana would be a much more interesting antagonist if they worked together with the same goals in the beginning and their confrontations arised from different views about how those goals should be approached.

Also since Nimueh finds out easily about Merlin's magic, and druids easily identify Merlis as Emrys without ever seen he before, it is hardly believable Morgana has such a hard time realizing about these issues. Not to mention neither Morgana and Morgause suspect of Merlin having magic, even after he escapes the serkets,  pretty lame.
