Summary
I wrote this story with the idea of exploring what happens in between the flashbacks and the mini-episodes that go from Edinburgh 1827 to the moment Aziraphale and Crowley meet again in 1967, because there’s a thread that ties them all together, and that thread is holy water.
I wanted to stick to canon as much as possible, but obviously, with the Ineffables I can never quite keep my urge to see them together under control, not even in one-shots, let alone in a long fic. So yes, there’s a completely non-canon love confession, and a period where Aziraphale and Crowley are actually a couple.
Another small non-canon detail: at the beginning of the story, Crowley doesn’t live in Mayfair but in Bloomsbury for plot reasons.
The original Italian title is a common saying whose literal translation would be “Like the devil and holy water.” It refers to two opposite, incompatible things or people that repel each other. Since it’s impossible to translate it faithfully into English, I chose an alternative that conveys the meaning of the original expression, though sadly it loses the reference to holy water.The fic is complete, I’ll be posting one chapter every Sunday.
