Sam studied Dean's tattoo closely, not liking the implied threat behind it. His frown deepened as he regarded Dean thoughtfully, wondering what anyone could've gained by drugging him. He didn't have to tell Dean that he didn't think the other man was fine, his expression said it without him having to.
Still, Sam was relieved to find that his shoulder slap hadn't thrown Dean for as much of a loop as it might have. He paused for a moment, catching the smile Dean sent in Shannon's retreating direction and cleared his throat. "Yeah, you're my brother alright," he said, his tone a little low as he stifled the urge to roll his eyes.
He shook his head and sighed. "No clue. I've been trying to piece everything together, but there's nothing the people we've met here have in common. Some have certain abilities and others don't. We're not even talking the same timelines here. I don't know of anything powerful enough to do something like this, or what kind of motive they'd have to bring us all together."
