[He fidgets with the hem of his shirt during Merlin's mini monologue, the weight of his actions beginning to settle a little more heavily on his shoulders than it had before... and he even apologized already! He's a man with secrets, he can respect someone wanting to keep something like to themselves

It's that last part that almost crushes him. He went and upset someone who actually likes him! Ugh, he's such a dick. But he's not going to wallow in this one man pity party! He's gonna make up for it, dammit, and fix it. He can't let Merlin regret this!]

Oh, no, man! I never thought you were pretending to be a prince or anything. That part's pretty obvious! You've got, like, a super princely demeanor and all that. Confidence, talent, smarts, the magic and looks to back it all up? Like who wouldn't think you were actually a prince? [Pfft.]

And, listen... I won't tell anybody else what I know. And like, if someone comes to the same conclusion I did, they probably just know the weird variation of your story, and it wasn't me that told'em. I'll pinky swear right here, right now, that my zips are lipped. Scout's honor.

[But was he ever a scout? Who knows.]
