Is it a show about SPIES? Is Meg a secret agent and Cas is her handler? Sam is the guy who doesn't say much and is terrifying and everyone calls "the cleaner"?

I feel like there could be a fantastic fic meme/challenge writing stories based solely off these pictures, with no necessary to connection to the show at all. I would TOTALLY read a fic where Cas is some kind of Secret Agent Man and Sam is a high-functioning sociopath-cum-assassin for hire.
