Experience Tumblr like never before
I've got this little plot idea in my head, where TFW go on vacation, and Dean says to Cas smth like "No, you're not going to a beach resort in a suit" so he makes Cas wear his clothes. Cas does what his friend says, though he doesn't understand, what's wrong with his trenchcoat.
Well... This decision had a much more unexpected result for Dean... Who knew, what Cas was hiding under all these layers.
