Anders simply walks up next to Yuna, and bumps her hip with his as they walk.

Understood. She leaves her work where it is and follows.

(She is not looking forward to having to do that sort of thing. But that she is certainly not trying without actual indication she's supposed to be.)

Lunch is the same set up as breakfast and dinner the previous day, all of the household coming together. One of the servants passes Elvira a plate, already with food on it. 

"I thought after lunch you could show Elvira around the library?" Yuna says to Andrew.

"Sounds good to me. What sort of books do you like?" He asks Elvira.

She eats food that she is given. They continue to be letting her taste it. She can pay a bit more attention to that, at the moment.

At this point it's almost odd to get a normal question for once. "Adventure novels. Some nonfiction." (She has to be careful with the adventure novels, but they're common enough on recess and enough mages like them that it's not been taken as suspicious that she does.)

"Older stuff, I'll bet. Like Yuna."

"You say that like you won't read the first history book that's handed to you."

"I am slightly more choosy than that, thank you very much."

She's not sure what he's talking about or why he said that about Yuna. (At the least, 'liking the same books as a human' isn't something she's tended to hear of mages getting tortured over.) Is he trying to tell her she should try talking to Yuna about 'older stuff' when Yuna comes for the sex? (Older adventure novels or older nonfiction? Older by publication date or by setting?) (She does note apparent book preferences to herself, Andrew's and since she's been given it (truly or not) Yuna's as well).

The rest of it - fits, if Yuna likes an 'anti-mage-slavery' thing - of course one reads what's handed to one, generally, there's not going to be anything else. So if Yuna likes hearing how different it is here, that would be right on.

Nothing in there sounded like a question to her, so she waits.

"Do you? Like older stuff? Like the classics?"

"I'm sorry, I don't understand." (Still not sure exactly how she's supposed to be talking to him, here.)

"Do you like books that were written many years ago? Or ones from closer years?"

By publication date, then. ...She supposes someone might have taste about that like many do about subject matter or style. "Haven't been particular." (That phrasing's risking a bit, but that just continues to be how trying for more information faster works.)

“This could be a chance to form a preference. We’re very opinionated in this house.”

Nod.

She's not sure if that's instructions or advice, but either way she'll take it and be glad. (It's also of course weird either way, but she's already clear on that aspect of the household). She considers if it's likely to be a problem if she says thank you; decides it's also worth the risk.

Smile. "Thank you."

"You're very welcome!" Andrew seems to settle at that.

Yuna dips her head to hide her pleased smile.

Once everyone's finished eating, Andrew turns to Elvira. "Wanna go to the library now?"

She was trained in body language reading; she notices the smile. That suggests she did something in the right direction, possibly. That's good. (She considers preferences. It would not be a good idea to show high preference for something she actually liked overmuch; too much risk if she - gets invested, and it ends up denied. Something she likes but not to that level would be what to use.)

Internal flinch but this is how they do things here and so she needs to learn it and so that is what she is doing.

Smile. "Yes, thank you."

"Come with me, then!" Anders leads the way.

Field mages in cover can give orders to other mages so as not to break cover, so there's an internal flinch but him saying that is informative and not just terror-causing.

Quick look to Yuna (which might get her a reprimand, if she's supposed to just obey, but this one's a risk both ways and she'll take it). And if that gives no indication otherwise, she goes.

Yuna's deep in conversation with her father, nodding at something he's saying and is not paying attention to Elvira. 

Then she goes. 

Andrew takes her to the wing she hasn't visited yet, and into a not-insignificantly-large room, filled with books.

That is a lot of books. But she's aware of the concept of libraries. She waits for some indication of what she is to do here.
