Glass shatters everywhere as he run and crashes into mirror after mirror. Blood trickles down his forehead, as fragments get embedded in his flesh, but he keeps going forward, and onward.
He slips and falls, but picks himself and continues charging forward, towards the light. Each time the light draws near, and he thinks he has found it, only to find it's a mirror and he crushes it to pieces.
He's in a bloody mess by now. Blood all over his face, and shreds of glass cover his flesh. And there's a mirror in front of him, and he's disgusted by what he sees. The monster, the beast, a useless blood-dripping carcass.
And, out of the darkness, a bat whacks him at the side of the head.
And out of the darkness, a voice springs within his head.
"Why so serious" and an evil laughter rumbles through the cave.
The bat falls again, and he reaches forward, his fingers grasping for the mirror; to shatter, to break, to kill the shadow behind.
Only to realise it's not a mirror.
And the bat falls. For the last time.
