Delightful! :D I love when Crowley gets philosophical. And, surprisingly, he's not even drunk! XD I completely agree with him that there really IS only one sin, and you've nailed it on the head.

Crowley breathing Aziraphale's wing well. You took that idea from how he healed the dove in the book, yes? Very very nice. :)

The image of Aziraphale crocheting is going to stick with me, probably to the point of becoming fanon. It just suits him too bloody well.
