Knock knock:
Trick or Treat!
Hnmmm: For you, lovely? A bit of that age-os-sail Merlin AU that won't leave me alone!
Merlin. None of the crew called him "the prisoner" or "the survivor". They used his given name, as if he were a friend. To some of them, it seemed he was. Lancelot and Gwaine, in particular, spent every spare moment down in the Brig with him, talking and laughing. Merlin himself seemed perfectly content in the bowels of the ship, surrounded by iron bars and sturdy planks. Happy enough, anyway, to insult Arthur with a sharp sort of glee every time they spoke. Worse, he rose to the bait every, single time. He was a captain and a prince: the epitome of control, but there was something about Merlin that slipped beneath his guard to needle at him, making him stoop to snarling and bluster, both of which just made a small, weary smile tilt Merlin's lips. The boy got to him. That was all. No one spoke to Arthur like that, as if his rank was nothing. No one dared. They looked at him and saw the man that would one day be their king. They respected him not just for the station of his birth, but for his deeds in battle and in defence of their kingdom. Merlin didn't respect him at all.
