Prompt: "Red handed"

[sirithromeniel]

Prompt: In episode 10 of season 3, when Merlin creates Dragoon he says to Arthur "You have caught me, red handed." I want something where as he says it he shoves his hand up, making it look red. Just...Dragoon gets established as having the weirdest sense of humor.
Characters: Dragoon!Merlin, Arthur, any assorted other characters
A/N: Just really, stupid puns and weird sense of humor. Especially in contrast to how seriously everyone takes everything.
