What was your favourite episode in season 3?

My favourites are:
1. The Goblin's Gold- Very funny. Richard was so great as the Goblin. So bad!! And Arthur's grin when he bumps into Gwen at the end. So cute!
2. Gwaine- What can I say it's Gwaine.
3. The queen of Hearts- Such a Arwen moment. The picknick scene when Arthur says he wants to be a farmer but he would make Merlin do all the work. Very funny. And when Arthur says he would give up his trono for Gwen. I think I nearly cried!
4.(Not in order but) The Changeling- Although I hate her because she's going out with Bradley( only joking) Georgia King was brilliant in this. I've seen her in other things but in this she showed how funny she can really be. The scenes with Arthur and Gwen aswell. When Arthur nearly cries I almost cried too!
5. The coming of Arthur part 1+2 Such an epic episode.

The Coming of Arthur Part 2 is my absolute favourite - I loved everything about it. Arthur acknowledging Merlin's wisdom, the knighting of... well, the knights, Gwen doing something other than giving Arthur a pep talk &, of course, 2 epic (and public) kisses between the future king & queen of Camelot.

I also loved queen of Hearts - It showed Gwen just how committed Arthur is to her. I loved that Merlin was willing to throw himself under the bus to save Gwen's life.

The castillo of Fyrien - Gwen opening up to Arthur a bit about her life as opposed to their conversations always being about Arthur. The Merlin/Morgana confrontation - I amor Merlin standing up for his friends.

Umm, the names arn't on the parte superior, arriba of my head but
queen of hearts-It was HILARIOUS! Old merlin<3
And
Gwaine-Nuff said

I can't choose between the first, segundo and final episode, because all of the Mergana moments were absolutely amazing!!
