"Oh," says Aziraphale, relaxing a little. He has no basis of comprehension of the word(s?) she's used except context, which might leave it anywhere between 'spouse' and 'consigliere', but an oath is good.

"By 'vermin' I assume you mean the humans," he says hesitantly, still frowning at her. "Very well."

He really wants to go. Back to the Base, or better yet, to his shop, where he can read and drink. And he ought to let Crowley know there's another of these things in town. Actually, he thinks with a start, what would happen if Lucifer found out about her? Would he try to destroy her, or try to use her? Neither option is very tolerable.

He sighs heavily. Blast his innate good intentions. "Is there anything you need?" he asks, his tone curt and skirting the edge of impatience. "Shelter? Food? There is some infrastructure in place, for those of us who've been displaced."
