I was starting to think that I was going to have trouble with something I had promised about the episode simply because it looked as though it was going to be a familiar plot, but I was wrong.
I think that this is one of my favourite episodes so far this season. From the opening scene I just felt that this was more than some knights out with their Queen, they were friends as well, and that was conveyed more than comfortably by the actors.
That Morgana was out to trap them once again was the only bit for me, her plan itself was different, clever and apparently effective.
I thought the Dark Tower was superb, creepy, almost scary in places with the random screams punctuating things very nicely.
There was a real sense of unease and terror in the false images that plagued Gwen, and it was nice to see a form of brainwashing in effect - and one that worked at that.
So not only did we have the shock of a regular being written out of the show, but a brainwashed Queen working for Morgana.
Which gives us something more to look forward to, can Gwen be saved, or is she going to have a bigger, darker role to play before the end of the season.
