"Notherenotherenothere..." he muttered to himself, too scared to punch. They liked it when he fought. They seared the flesh off his bones when he fought.

Last time the not!Sam was there, he pulled his heart out and held it up to him.

See Dean? It's all mine, always was. And then he'd swallow it all down, bite by bite.
