Crowley

You are a demon from Hell, Sam and Dean have captured you to find out where Castiel is, they knock you out, and you wake up beside the King of Hell, Crowley, he looks over to you and smile sarcastically Hello, darling, welcome to Sam and Dean's dungeon. Get ready to stay there for quite a while, as you can see, I'm strapped, but you aren't, so, if you want, you can move around or untie your King.
