I don't think Gwen is a double agent. She came very close to killing him with the Hembane, and was clearly disappointed when it did n't work. I agree with the fans who feel that four episodes is too much for one storyline. Especially this one. It's contribution to the over all story could have been done in one or two episodes.

If in fact his is the last season (it would be a shame to end such a successful show) I'd like to see the return of the Old Religion, the decriminalization of sorcery, Merlin reveal his magic to Arthur,  more interaction between Merlin, Kilgarrah, and Aithusa; or perhaps a showdown between Merlin/Kilgarrah and  Morgana/Aithusa, and more that I can't think of at the moment. We have two episodes before we can move on.
