“Time is the bastard offspring of an incestuous act that God committed upon reality." Merlin to Arthur in "Arthur Rex”

“[Arthur] "Er... Just how much did you have to drink?"Merlin frowned at Arthur... Both of him.”

“It was Arthur's welcome alone, I believe, which turned the tide of misery for Merlin.”

“Arthur is no fit king. Uther's bastard, Merlin's pawn, he is lowborn and a fool. He is wanton and petty and cruel. A glutton and a drunkard, he lacks all civilized graces. In short, he is a sullen, ignorant brute.All these things and more men say of Arthur. Let them. When all the words are spoken and the arguements fall exhausted into silence, this single fact remains: we would follow Arthur to the very gates of Hell and beyond if he asked it. And that is the solitary truth.Show me another who can claim such loyalty.”

“[Arthur to Merlin]I'm the Prince of Wales, and you're Welsh. I can do whatever I bloody well like to you.”

“All that winter's day and far into the night the kings twisted and squirmed, but Merlin held them in his iron grasp and would not let go. He became first a rock, and then a mountain in Arthur's defence. Arthur stood equally unmoved. No power on earth could have prevailed against them . . .”
