Good Omens: The Pharaoh's Son (Aziraphale x Crowley)
Crowley and Aziraphale have known each other for a little while, just a few millennia. But, something is coming, something that has Aziraphale very, very worried. Crowley can't just up and leave no matter if the angel begs and pleads, probably.
This is the demon and the angel's first big falling out that will change their lives forever.

"And, why exactly would I do that?"
"Because I," the angel paused. He seemed unsure himself, but it didn't seem to stop his resolve. "Please, it really is frightfully important that you leave. I really do wish I could say what is going on, but if word got out that I'd warned you, well, let's just say it would mean a lot of trouble, possibly for us both."
"This wouldn't have anything to do with the pharaoh's second son, would it?"
