Dean's first thought after tasting freedom was Sam.
His second was quenching the insatiable thirst that consumed his very being.
He chugged the water as if it was his life force.
Then he went for the food.
Oh yea baby.
Mom and Pop dives in the middle of nowhere were good for something.
Dean grabbed a smorgasbord of chips, cookies, candy, and soda.
He wasn't taking any chances today.
Breaking through a haze of fog and smoke and dust made a man hungry.
Clawing your way out of the depths of Hell after four long months made a man ravenous.
