Towards the very end of Pratchett and Gaiman's Good Omens,
after Adam has decided not to destroy the world after all, and the moment of the destined battle has passed without incident,
his father, the Devil himself, is on his way up to the surface:
The ground began to shake. The noise was like a subway train, but not one passing under. It was more like the sound of one coming up.
Crowley fumbled madly with the gear shift.
“That's not Beelzebub!” he shouted, above the noise of the wind. “That's Him. His Father! This isn't Armageddon, this is personal. Start, you bloody thing!”
Aziraphale, Crowley, and Shadwell march forth to face Him, but Adam does ... something:
Adam looked around. He looked down. His face took on an expression of calculated innocence.
There was a moment of conflict.
But Adam was on his own ground.
Always, and ultimately, on his own ground.
He moved one hand around in a blurred half circle.
... Aziraphale and Crowley felt the world change.
There was no noise. There were no cracks. There was just that where there had been the beginnings of a volcano of Satanic power, there was just clearing smoke, and a car drawing slowly to a halt, its engine loud in the evening hush.
Apart from an absolutely cringemaking overuse of the word "there" in a single sentence and paragraph ... what actually happened here? Adam's biological father, the Devil, is coming up from Hell, then
suddenly it's only his adoptive father, Mr Young. Did Adam somehow transform the Devil into a human? That seems unlikely. Did Adam dismiss the Devil, and it's only coincidence that Mr Young turned up exactly there and then? I think there's something I'm missing.
