I am a bit late and sorry if it has already been said before but I just wanted to talk about the scene when Arthur and Merlin are with the two knights in the courtyard. When Arthur says "this is Merlin" you can see Merlin a little shy with a small smile like "hello, nice to meet you" and then Arthur says "he loves hard work". I don't know but when he realise that he talked about him just for work, I found Colin's face priceless !!!!
