She waits in the room, after, for a while, and - Nona doesn't come.
They might only get one chance. And Nona wants out too, and Etty shouldn't fault her for waiting, but she writes those thoughts on her scroll in terrible handwriting and cries and wishes that things would go faster.
She doesn't want to be one of the swans.
She's tried talking to them some more - tried imitating them, and when she does that they'll act like she's one of the flock and stop being afraid of her, but she can't get any glimmer of human memory out of them whatever prompts she tries.
She does not want to be one of the swans.
And the next girl won't even have the hope of Nona, the comfort of maybe soon.
She holds Nona, when Nona meets her in the orchard, and she thinks maybe soon, and one night she says:
"Do you - have any idea when you'll be able to say it?"
Another animal summoning spell requires her to urinate in her best approximation of a perfect circle wherever she wants the animal to appear. A third requires that she have the severed foot of the desired kind of animal, whereupon once the proper rituals are complete she can summon as many of it as she likes.
"I found some healing spells but nothing general, not in the books. Some of the specific ones will work on things of narrow parameters - like the type of implement. If you have something made of steel to use to get the blood you can be patched up after. All-purpose versions, like what you had before, I'd have to go into his notes for."
She summons a deer. She kills the deer. She paints its blood on all the things she needs to paint its blood on, then pours the last few drops over her head, as directed.
She sits at the head of the dining room table and summons a feast.
Nearly every spell that accomplishes something interesting involves a component that is either sacrificial in some way or just plain disgusting. There is a loose category of cleaning spells that only need water and occasionally soap for the setup - a common thread is that once set up, many spells can be repeated by an effort of will or a token gesture - but that is really about it.
Etty decides she is going to be Library Person and Nona, who plainly has a higher or possibly nonexistent disgust threshold, can be the Actual Spellcasting Person barring emergencies. Etty does find some soap and water and re-casts the spell that kept the castle clean by herself, though.
