Rain
Rain had been pouring down the Earth for like hours now but there was no sign of stopping from the sound of it. Dean shot a wary gaze to the wide window and the thin lacey curtains covering it – a useless thing in the nine-year-old's humble opinion—they could not stop him and Sam from staring right through the rain, let alone from the thunder and lightning that cracked almost every five minutes.
Alone only with little Sammy in another motel room – their father had yet to return from a job, Dean did not dare shut his eyes even for a second. Not in this weather. Not when closing his eyes meant letting Sammy out of his sight, although the kid was curled up right here with him, never far from his embrace.
"Dean."
Suddenly a tiny, chubby hand rested on his cheek.
"What is it, Sammy?"
"Sleep, Dean," Sam mumbled.
"Yes, Sam. Just close your eyes, okay?"
Now it clasped at the side of his neck.
"No, Dean. Sleep." And the little boy pulled him closer, snuggling into his chest, and sighed softly in an attempt to draw him into the dreamland.
