User blog comment:Arthurlover7/What is your favorite episode of each season?/@comment-5324292-20130128000323

Series 1: The Labyrinth of Gedref

Series 2: The Once and Future Queen, Sins of the Father, Lady of the Lake, and Sweet Dreams. (I really liked Series 2, with Arthur and Gwen's relationship just starting. And I really liked Morgause in Sins of the Father. And I loved Merlin having a girlfriend. Teehee. :) )

Series 3: Gwaine and The Queen of Hearts

Series 4: Aithusa and A Servant of Two Masters

Series 5: (I haven't really seen much of Series 5 yet, even though I know what happens. I've only seen up to Another's Sorrow.) Out of those, I liked Arthur's Bane (Part 2), but I think I'm going to like With All My Heart and The Dark Tower.

My overall favorite is probably The Once and Future Queen, since there's not really a lot of drama and it's mostly just about Arthur and Gwen's blossoming love. :)
