Mission completed, Dean lay back on his pillow with a sigh. "Damn, I'm tired."
"You should sleep."
When Dean didn't answer, Sam touched his forehead. It felt a little warm, so he handed his brother some aspirin and a glass of water.
Once Dean had swallowed them down, Sam went to the bathroom, coming back with a damp wash cloth, the coolness of it on Dean's flushed face drawing out a drowsy murmur of appreciation before he drifted into sleep.
Sam took one wary look outside, then sat back down beside Dean and powered up his laptop.
Time to hunt.
