Two Deans stood before you. Identical in everything - hair, face, eyes, panicked fear in their expressions. They'd been pitching their argument for an hour now, trying to convince you that no, they were the real Dean, they swear!

You thought you could pick Dean out of anyone in a crowd. You could. But how do you pick Dean from himself? What happens when you make the wrong choice, and Dean's dead, and the shapeshifter masquerading as him is all that's left?

The gun in your hand bounces between the two of them, each of their hands raised in mock surrender. Anyone would balk with a pistol aimed in their face.

"C'mon, baby," one of the Deans says, desperation in his voice. He's been stood out here for so long, trying to make you see that he was the real one. Couldn't you tell? "You know it's me. You know it."

The other Dean shakes his head vehemently. "No, don't you dare listen to him, baby. Don't you dare. I'm Dean."

Your hands were trembling around the gun's grip, finger over the trigger. What the hell were you supposed to do?
