Every single episode! Why do all of the episodes surprise me than? (Even though I've seen all them twice I still get tensed):)
In a land of myth and a time of magic the destiny of a great kingdom rests on the shoulders of a young man his name.... Merlin
Arthur: "You can't hide anything from me, Merlin." Merlin chuckles. This is basically the whole show
Miranda Ferguson is a genius. This is probably my favorite Merlin pin ever.
One of the best sassy Merlin moments.
Merlin: Magic is neither good nor evil it is a tool like a knife is a knife evil? Only if the wielder is evil. - the house of hades, rick riordan
Merlin - “Do stop moaning. At least the work’s interesting.”
this is the most hilarious, and accurate, description of season 1 that i've read so far
