She wanders the city, goes back to where she's staying, sleeps. Wakes, wanders the city some more. Spends allocated money on further food and eats it at appropriate times and intervals.
She's been in small private spaces alone in field cover before. For hours at a time and overnight, even - it doesn't come up often, but it does ever.
She can't say she likes it very much. She's taking it for granted that she's being watched - by scrying or something, probably, unless they watched to see what room she got and had someone put in a camera while she was out. But she doesn't get any feedback off that like she might of a minder or a handler in the room. Even wandering around the city, which was weird enough for that long a time period in a row, she could presume that people might react somehow if she started doing something at least they knew she wasn't supposed to.
And given what circumstances are usually involved in being in small private spaces alone out of field cover (not that this place resembles a punishment cell much, at least), the associations are really not helping matters.
But this is what she has, so that's what it is.
There's some kind of matt on the floor, which she does appreciate. She's a field mage, and she's trained in and used to sleeping in beds in field cover as needed, just as she's used to sleeping unanchored, no waking up panicking from the lack of the chain from her wrist to the floor. Given everything she's managing at the moment, it's still rather nice not to have one more thing.
She sleeps. She wakes. She goes out.
