Hey gay demons, just wanna say spoiler warning for s2 e6, and this is my theory as far as I know, (if you have seen something like it lmk) and it is my first every theory!
The break up was started by Aziraphale speaking first; so if Crowley had spoken first, maybe Azi would've changed his mind. Crowley said he would talk first, but then Azi jumped in. Crowley could've said and explained, changing Azi's mind.
Ik I wrote it kind bad, but yeah!
