This was supposed to be a one-shot but somebody asked a continuation so here's a little more
He finds him among brine and ruin. In a sweltering heat not of this earth, something scorching that vaporizes any good intentions one that comes down here may hold, let it be pavement for the road instead.
And Crowley has never seen an angel so broken.
Of course They did not kill him. There are things even They could not do without fearing heavenly retribution, things that transcend immortality straight into the realm of the foolishness.
But They could hurt him. They could break him in a million tiny different ways and Crowley observes every single one of them, commits them to memory so that one day the price may be paid in full.
"Aziraphale!" The name sounds rough in his tone of voice, a surprised noise more than a proper word and he is next to the other immortal in a heartbeat, one hand pushing against his shoulder for any sign of consciousness.
The angel sighs, head tilted back and his eyes are dulled, the clear blue Crowley once admired clouded in discomfort.
But they focus on his face gradually, blinking slowly, and Aziraphale smiles.
"You came for me."
Crowley swallows. He doesn't point out he is only here because They want him to be. They had Their fun, but everything grows boring eventually and if he has found Aziraphale it is because They allowed him to.
Because this too is part of his punishment.
"Of course I did, don't be daft." He says, using his free hand to tilt back his angel's face and there's blood covering the bottom of his face from a split lip. Something dark and bruised against his neck. His wings hand useless and limp, once pristine feathers in tattered ruins stained with red.
Something so human about him it hurts.
Aziraphale laughs a little, a pained little noise as he tries to move but the ropes chafe his already raw wrists. "Indubitably."
Crowley undoes the bindings easily and he allows the other to use him as a crutch as he painstakingly gets up from the chair he was confined to.
He buckles and the demon catches him.
"Can we go home now?" He asks. Something so hurtful, so broken, Crowley doesn't ever want to hear Aziraphale like this again.
"Yes." He says. "Let's go home."
