She'll order in a humidifier.
It has occurred to her, by now, that the researchers definitely don't know she's from another world. Which ... she feels like she should have been more on top of that? Should she have not let that slip? On the other hand, it's not like it would be hard for a shadowy antagonist to figure things out from what she has said.
She spends a little while trying to figure out if this is the kind of story where being from another world gets her locked up in a lab, or the kind of story where the moral is about learning to trust other people. She watches clouds scuttle across the sky.
The truth is this isn't any kind of story at all.
She hugs her knees, trying to figure out how to respond. Finally, she remembers something that her older cousin Peter told her once, at a different cousin's wedding, when she found him sitting on the dock with a mug, his feet dangling in the water: "tell the cops nothing, and doctors everything".
Disease researchers are probably relevantly doctors, she decides.
No, she tells them. She's never participated in a Pandemic Awareness Week, because she's from another world. And she doesn't have a mask, because she just came here with a book and her clothes and didn't realize masks were standard.
As soon as she's sent it, she realizes that she probably sounds delusional.
She tells them that they can check, maybe, with the teacher who found her when she arrived. She has their phone number.
She looks up masks on her phone, her eyes drooping closed for long stretches. She should probably nap again, but she wants to see what the masks are like. Something about the idea of wearing one in public really appeals to her.
