I just think it's wierd how people always write about Arthur being angry that Merlin didn't trust. With his life? I wouldn't. I got some really good friends but nobody knows everything about me.
Disclaimer: Don't own Merlin.
Trust: To rely upon or place confidence in someone or something.
"So we're you ever planning to tell me Merlin?" Arthur spat.
"Yes actually," Merlin responded, he was acting unnaturally calm despite having the single most important secret of his life reviled. Arthur didn't know where this cool attitude had come from. Merlin didn't know where his attitude had come from.
"When."
"Well obviously later, maybe when you were king, when you had the power to make magic legal. Because believe it or not Arthur I don't like committing crime. I don't like how under your fathers rule I'm not even entitled to breath. It's a very delicate situation." Merlin explained
"You should have trusted me! I wouldn't have told my father."
"Maybe I should have or maybe I shouldn't. You see my dilemma. Arthur you've never given me any real solid reason to trust. You may be a prince and you may be a prat but you're not entitled to all my secrets, those are mine to keep and I'd be a fool to hand them all out. Don't expect your future subjects to hand you their lives on a silver platter." Merlin suddenly changed the subject. "May I leave now I have chores to finish?" Arthur gave a vague gesture of dismissal, feeling empty. His fury had left and he was thinking much clearer now.
