[That definitely startles him; Crowley runs through a mental list of women he knows, that also know he's a snake (most of them), who might be able to make the connection between himself and an angel. Diana likely would, but he doesn't think Diana comes across as the sort of person who would give mice as snacks.

Who else could it be?]

It wasn't a woman that gave them to me. Who's been calling me your serpent?

[Like, it's true, but they shouldn't say it.

As for the glomming, Crowley turns to face Aziraphale, reaches out to gently touch his arm with his free hand.]

Didn't I say? There's a lot worse than this that you could want. [He'd allow that too, if it was necessary, but that's not the point.] Promise not to make it weird once the feeling's passed and I'll not complain about your displays.
