Awwww! That's great. I love the little baby-snake Crowley, and the... well, I love everything, really. Especially how you have Historical-A&C friendship and Heaven/Hell politics.

"Something small and squiggly fell from the clothes and writhed on the ground. Aziraphale, veteran of the Host who had just banished a demon multiple times stronger than himself, screamed and jumped back, throwing the clothes away from him."

This made me grin hard, and the baby snake and baby speech after made my face hurt. ((In a good way!))

Wonderful fic!
