"I don't know," he says, "I don't know." God works in mysterious ways, but Aziraphale can't even conjure up the strength to comfort himself with those words. "But let's get you inside now, please, Crowley."

He, very belatedly, noticed that Crowley is lying to him about his pain, and attempts to find where it is he's hurt. He discovers he can't tell where it is, but unlike with Anathema's bike, he knows exactly how Crowley is supposed to be, and so very easily performs a restorative miracle. Once he's sat Crowley inside, he'll have to come back out and do a few more of them, make sure everyone alive is in working condition.

Honestly, he can't believe it's over just like that either, and with so many dead. It's like they don't even care, like everyone around them was just a pawn. Aziraphale has never felt more faithless than in this moment, and focuses in on Crowley because he doesn't want to look back at all the carnage behind them; he seems to be on the verge of collapse.

Another rain starts, to wash this all away. It isn't blessed, since there are a few demons who get hit with it and haven't melted, but Aziraphale instinctually unfolds his wings from his back, and lifts one gingerly over Crowley's head.
