Dean always wore his signature flannel over a t-shirt wherever he went. To others, it seems like it can be too much, but it was perfect for him. He was able to get cold very easily because he got hypothermia a lot as a kid when John would leave him and Sam in cheap motel rooms.   After finishing a hunt with Dean, it was starting to snow, and the temperature outside was beginning to drop. It looked like there was going to be a blizzard, but you both luckily found a cabin in the woods.   As you both went inside, you could see Dean was shivering, despite trying to look like it was not bothering him. “It seems like we’re gonna be stuck here unless we go back out there,” he mumbled with a sigh.
