Dean's eyes widened slightly, but he wasn't angry. Then he got up and went to one of his bags, fishing out the bottle of aspirin that he hadn't needed since Sam was alive and made his way back over to the two of them. "Here, Sammy," he said gently, taking Sam's hand in his and placing two aspirin in his palm. "Take these, see if they help."

He would explain this to Alec later, but right now, he needed to take care of Sam. He didn't know if the aspirin would work, now that he was a demon, but he figured it was worth a shot.
