Sam stared out of the window and smiled. The snow lay thick and Dean, well Dean was building a snowman!
Some days Dean could be happy with the simplest things. Dean looked up, saw Sam watching and waved. Shortly Sam would go and join him, maybe have a snowball fight and then he'd tackle Dean, lay his brother down in the whiteness and kiss the snow away from his face.
Days like this were rare in this new world he'd created, a demon army behind him. Snow never fell anymore but Dean asked and Sam, well he made it snow.
