Sam hasn't seemed to notice you. Curled in on himself, knees tucked to his chest, head on his knees. Shaking almost violently, muttering under his breath. All of his words are unintelligible, all but one. "Stop," and he says it over and over. Until he hears you.

His head snaps up, lips parted slightly. Panting. Eyes wide. He makes no move, just.. admires. Studies you.
