"Sure. But I'm magical, aren't I? Who's to say I can't change a metaphysical property?"

"...I really don't think it will help."

"Maybe not," she agrees, "but—if we could convince people that worked and figure out a way to get more changers here and have them nod at food—we'd need to vet for trustworthy ones but—"

"This is the kind of thinking that led to Savo's idea."

"Yeah," she sighs. "But it looks like the main reason Savo's idea failed was that—people didn't believe him, right?"

"Yyyyes. I'm not sure you understand how little people believe in magic."

"Right, but that part I can literally demonstrate." She changes her hair colour to blue. "The summoning part, too—or, well, I can't summon, but you can and I can show you how."

"You can't demonstrate it to billions of people."

"No, not me, personally.—should I perhaps get out of your hair and instead go bother your—husband? I'm sure you didn't wake up thinking 'boy what a good day to be alien translator and things-explainer.'"

"...he didn't either. And he's not nearby."

"Yeah but I'm expecting he can point me at someone who can use me better. And I can go wherever he is."

"By - what, flying through the air? I mentioned we're at war -"

"I presume you got here somehow other than walking? Do you have—cars, that's a word that exists, and trains, you probably have some form of transportation. If you're worried about conspicuousness I can turn my wings into air."

"...of course you can. We got here by a helicopter shuttle from the train station, had to change trains twice."

"If I fly most of the way to the train station will I be in much danger of being spotted?"

"Yes, some people live around here, just not many."

"Hmm, what if I fly very high?"

"Birdwatchers." Sigh.

She rubs her chin. "What's the way here to the station like?"

"You can hike it, if you like hiking, but it'd take all day."

"Oh, all day hiking's fine."

...he gets her a map.

She accepts it. "I'm indestructible," she explains. "Even if you shot me that'd at most hurt a little and annoy me, maybe ruin my clothes and I can mend that. I don't get significantly impaired by hunger or thirst or sleep deprivation, either. It'll be boring but that's all it will be."

"If Zazi needed to dismiss you how would she do that."

"Concentrate on wanting me gone for a minute, but if you'd like to do that... I'd like to at least leave you a circle that summons me, specifically, if you ever change your mind. And one with bindings, the one she used had none and bindings are pretty important, most angels are perfectly nice but a not-nice one could cause a lot of harm."
