"Arthur had to wonder, whether he should not feel something, anything at all, that would hint at him being controlled by Merlin. Even as he tried, he still felt nothing." Merlin is heard saying things that he shouldn't have said, and Uther is determined to do whatever it takes to free Arthur from the sorcerer's influence - which might be more difficult than expected.

"His bottom lip trembled. Wetness stung his eyes, but Arthur sucked the tears away. He wouldn't cry, he would not. He did not deserve the release. He never wanted to be eased from this pain, because then he might forget. He might forget his Merlin. Arthur Pendragon, Sovereign of Camelot, Once and Future King, never, ever wanted to forget his Merlin." AU season five.
