Okay, Merlin was pinned to the wall. So, since Arthur knew he had magic he used a silent spell to allow himself to walk free, one he was too panicked to remember when Uther was around. Arthur, in his rage and confusion, didn't notice this and the two of them marched off.
Happy?
So, thank you for the reviews, onward we go!
Merlin had told Arthur the important facts: that he was born with magic; he had been using it the whole time he was in Camelot and, since Arthur saw that Merlin was holding something back, he reluctantly told Arthur that he was the most powerful warlock to ever live and it was his destiny to protect Arthur.
Arthur had sat on the window ledge, looking out of the window in thought. "Leave me." Was Arthur's only response to Merlin's story. Obediently Merlin turned on his heel and left. The only time he returned to to attend to Arthur for dinner.
It was tense, Arthur ate in silence. Merlin became the perfect servant he cleared all spills straight away, filled Arthur's glass as soon as it emptied and got him ready for bed quicker than he ever had.
Arthur leaned over to put out the candle and found a small, rolled up piece of parchment that read, in the smooth handwriting that belonged to Merlin, "I'm sorry." He looked up to see the back of Merlin's head leave his room.
A single tear rolled slowly down Arthur's cheek, all that he would allow. He didn't know what to think, in his father's time Merlin would have been killed straight away. Not even a trial. It was law. And Arthur should follow it, shouldn't he?
His father was already angry and ashamed of what he had done during his reign, what Arthur had thought was right. He may as well continue to defy him. Merlin hadn't hurt him, or Camelot as far as he knew.
Merlin was good, kind and certainly clumsy. Even in the gravity of the situation, Arthur had to double-check. Merlin? The most powerful warlock to live? If he hadn't just discovered that he best friend had lied to him for years, he may even had laughed.
He had given up on sleep and just lay awake staring at the ceiling when he heard the sound of hoof beats. He looked out to see a hooded figure on a black horse riding at full speed out of the city.
Merlin.
Sorry, short I know but it felt like a good place to end.
