Gorgon: Have you ever heard the story of the black snake? Once there was a crafty black snake who kept eating this poor chicken's eggs. She couldn't watch them all the time, you see? The black snake would wait until she was gone... and then slide one of the eggs into his mouth and crush it in his throat. Now, this went on until there was only one egg left. But when the chicken left that egg, just for a moment, the snake swallowed it up. But for some reason, he couldn't crush it in his throat. The chicken had hard-boiled her final egg just to choke the snake. And the snake died.

Castiel: Why are you telling this story?

Gorgon: Because I can't quite tell if he's the chicken... or the snake. (meaning Jack)
