Death of cas

It was a really cold day when cas died. Hell I remember it like it was yesterday. As I said it was cold, Sam and I had gone on a hunt for a vampire attacking campers in the in the cabins of the Colorado Rockies(flashback moment). " Alright so what, a vamp gets the kicks out of making messy kills with his victims. I don't know Dean. It just doesn't seem like a vampire at this point." Sam had been going on with this hunt for hours. " ok so what if it's not a vampire, Sam we know how to kill literally any thing out there. Maybe it's a werewolf you never know."
