Isabella studies her new alethiometer dictionary between magical assignments from Metis. She even found a book of sample questions and answers - the English originals of the questions and the professional readers' deciphering of the answers are given, and she can try her hand at composing symbolized versions of each. She uses the exercises sparingly. There aren't that many of them, and she doesn't want to contaminate her knowledge of the subject while she's still learning, not until she has an actual alethiometer in her hands and can try asking it questions to which she already knows the answers to calibrate.
"I don't mean 'the sniffles' kind of flu, I mean it'll take the targeted person a rather heroic effort to drag themselves to the bathroom to puke and back under the covers to fall unconscious for another twelve hours," Isabella says. "There's a reason I don't want to just curse some random person even with a counterspell prepared."
Isabella looks at her translation in progress, then sets it aside. "...Okay. Stop when I say, though, if I say it. I might."
"Okay," says Petaal. Kas unperches from her, and she shifts bat to fly into Isabella's lap and linsang to snuggle up in it.
Isabella's got enough silk on to make this not technically daemon-touching. It is unsettlingly close nonetheless. She carefully settles her hands in her lap, letting Petaal be the one to complete the contact.
Kas curls up happily on the floor.
Slowly, Isabella pets the linsang in her lap. She's soft.
Actually, they both do.
Isabella gets used to this faster than she expected. She keeps an ear out for Metis, who could return at any time, but she carries on petting Petaal with focused attention.
After a little while of everyone enjoying themselves, Petaal turns into a fluffy long-haired cat and requests belly rubs.
