Where did you meet him? "Friend" is kind of a strong word. He's my servant.
[A hell of a good one too, if he'll say so himself.]
You're a knight? [He knows a family of knights so yes, this is relevant to his interests. He's not going to say anything trite like "but you're so young!" considering he's a 14-year-old Queen's Watchdog, so ymmv.]
