:p Uther is one of those characters that can make you feel only complete hatred for him in one episode, and in another episode, you sort of pity him and are okay with his existence. <--- literally couldn't have said it any better xD
I had watched doctor who before Merlin. And seen this episode before it. So when i started watching Merlin I couldn't figure out why he looked so familiar. When I looked it up I totally freaked out and then rewatched the episode just to watch Colin.
