The question about the kidnapping of children goes completely unheard. It's a good question and surely Aziraphale would have something to say about it, but he's rather taken with the description of "sparkly" being used in reference to something he was comparing Crowley to. He hadn't thought of fae wings as sparkly, not yet, but now he is. Such a thing wouldn't suit Crowley at all, but it would certainly amuse Aziraphale to see it.

Well, that, and Aziraphale's thoughts are starting to get a little more hazy.

"Are they sparkly?" he asks, a little distracted.

His arms tighten around Crowley as he gives it a little more thought.

Then he adds, "It's a Fae's nature to beguile and trick others. From little to small things. And they do have a certain style about them."

Also, they are very imaginative creatures.
