Muriel reading Aziraphale's diary is a cute thought. Them reading Aziraphale's depiction of Armageddon't and finding out about body switch, while still being loyal to Heaven (and they are loyal to Heaven at the point of S2 final), on the other hand?....
Not so much, I'm afraid.
#yeah I'm convinced Metatron already knows about it#and that was what he was hinting at while talking about “looking into Aziraphale previous exploits”#but just an idea of how many possibilities there are to fuck up their only ace in the hole when it comes to Heaven's wrath#Gabriel knows about body switch now#Metatron most likely knows too#Muriel will likely find out about this too and there is only a hope they won't be that loyal to Heaven at that point anymore#Cause there are still archangels who don't know#and what can they do with this information?#good omens#good omens season 2#good omens s2#Muriel#good omens theory
