I agree that this season is quite good. It has  some elements of the earlier seasons formula of having a creature or "bad guy" who threatens either Arthur, Uther, or Camelot. Then, Merlin and Giaus figure out what it is, or why it is,what Merlin has to do, and Merlin eventually overcomes it. But this season deals mostly with the development of the Arthur vs Morgana storyline, It culminates with Morgana's second brief reign, and how Merlin, Arthur, and the Knights save Camelot in the end. The season is a bit darker than the earlier seasons, but is not as dark as the fifth season.

There is one thing that I am left wondering, and that is why Agravaine would forsake Arthur to support Morgana. As Agravaine says if he betrays Arthur he "betrays his sister, and that he would never do". But he does! And, we never find out why he would do so. We know that he has great hatred for Uther, but why Arthur, who is half Ygraine? We don't even know how he knows Morgana. He comes to Camelot after Morgana is gone. How did he get to know her so well that he would turn against his sister's only child? Does anyone know?
