Those come hither eyes were betrayed by those uncertain words. Or so Anthony thought as his mind turned towards a slightly more serious path.

"You've a point. From everything I've read it is supposed to be a very dangerous thing to allow a demon to become attached to you. Especially if you don't know their real name."

"I could tell you what it was. It's probably a good idea, just in case... you need to stop me. I don't think I liked it much so don't go spreading it around. I didn't even tell Alec. If anything goes pear-shaped I want you to be the one to... whatever one does with demons, banish them, seal them in a jar."

The rest was whispered so much softer than anything else he had said thus far as he wanted only Aziraphale to know.

"It was Crawley."

And as things were soft and comfortable here in the alley he leaned in to steal a kiss.
