Take your minds back to fake Sam and Dean when they knock on Garth’s door on the boat and Kevin sprays them with Holy Water. I take it these were demons, who were pretending to be Sam and Dean if so why didn’t their skin burn when Kevin sprayed both Sam and Dean? Did I miss something?
Yesterday I put up a thread on the forum and they came back with some interesting scenarios see what you think, and see if their theory is legit. I like the idea of them not being demons but Shape-shifters as they didn’t react to the Holy Water.
