COME ON! IT'S THE OLD WEST! COWBOYS AND HORSES AND EVERYTHING! PLUS DEALING WITH SAMUEL COLT (which is definitely plot-driven, given the history of the character, this could be a very interesting episode in general and not something filler or cracky at all) AND HOW ELSE ARE THEY GOING TO GET INTO THE PAST LIKE THAT?

I TOTES WANT CASTIEL TO BE IN THIS, WITHOUT A DOUBT. ;D
