I love it! Such a great vignette. I've not yet read Good Omens, but it is on my To Read List. (I'm the one with the Obscure List of Fandoms TM - seriously, I once wrote fic for ITV's The Royal)

I get the rapport between the two characters, the humour and irritation, the banter hits all my slashy buttons ;-)
As well as all that, the talk of dodgy translations into random languages just makes me giggle - having studied Ancient Greek I totally get how dangerous the wrong phrase can be in ordinary writing, let alone the Necromicon ;-)

Very cool fill. Thank you.
