Spent
Dean was curled up in the backseat of the Impala as Sam drove. Sam couldn't be certain if Dean had just passed out from exhaustion or actually let himself fall asleep. It didn't matter really… Asleep? Unconscious? At least Dean was getting some rest.
Sam pursed his lips, his fingers curling around the steering wheel even tighter. The long road to Bobby's seemed especially quiet tonight, nothing but the sound of the engine humming away and Dean's soft breathing. The younger Winchester sighed, glancing back at Dean in the rearview mirror, ugly purple bruises standing out against his pale skin.

A/N: E/O Challenge. Word was "spent" so I thought of being spent physically or emotionally and wound up with this. Hope you like it!
