The second Loki says 'flee for your coin' is when Clint stops paying as much attention to his wayward arrows and more to the fellow boy. Brow furrowed. And then he just...keeps talking? In the strangest fucking way? Opens his mouth to argue that he doesn't think Loki is just some dumb kid, that he doesn't think anything about him, but he's starting to think he's a weirdo who needs picked up by whatever guardian he wandered away from--but Loki keeps talking, and Clint's brow keeps furrowing.

And then the motherfucker uses some kind of genuine actual magic, and Clint startles back several steps.

His bow is half raised. He does not take the arrow. Looks at it suspiciously like it's going to disappear (and find itself embedded suddenly in his back). Looks at Loki.

"What the fuck are you? Did I step in a damn fairy circle?"
