Pre-Arrangement query
I've been wondering this for quite some time...
Is there actually anywhere in canon that specifically says Aziraphale and Crowley fought in a physical manner before the Arrangement? Yes, they were Enemies, but did they have knock-down-drag-outs? So far, I cannot find anywhere this is written, nor even inferred. Is this only fanon?
If someone has a page or line that does clearly state this as fact, please point it out to me. I feel like I'm missing something....
