Well, if Lucifer believes in him, then perhaps things will go smoothly, after all. (And there's a sentence Aziraphale never expect to think, let alone gain reassurance from.) "All I can do is be myself, although I do think it's a little presumptuous of me to show up unannounced."

Although maybe that doesn't matter since Moloch doesn't even have a structure he calls home. "He doesn't --" The angel sighs and shakes his head. "Of course he doesn't. I'll make sure the perch is one that's easily portable. And even if cleanliness is not an issue, he should regularly groom both animals. Harry never had parasites, but he loved to be brushed. It's a good way for an owner and a pet to spend some quality time together."

Aziraphale turns down the street they had come from, and sure enough, there is a pet supply store on the corner, selling all manner of products. The shop is modern by Earth standards, and the automatic glass doors slide open wide, leaving plenty of room for Lucifer's wings to pass through.
