Series 4 was a not as good repeat of Series 3. (It was still very good though) Morgana took on the role Morgouse form Series 3 and Agravane took on the role Morgnana had last year. They reapeted the enemy within arc and it wasn’t even as meaningful since we only knew Agravane for 5 minutes before we realised his betrayal rather than 2 Series. Also the finale was the same except this time the army was mortal so they actually lowered the threat.

Just a question which Series did you see first?
