She gives it to him.

He puts it in his pocket. 

"Thanks for not mind-controlling me I guess. Not that I'd be mad if you had, I guess, so I don't know if it makes sense to thank you?"

"I mean, I think not mind controlling people is, like, below the minimum decent person line and therefore not something people really typically thank each other for."

"I am really confused about what humans use 'thank you' for but often they use it when they do something that creates debt and not mind controlling someone doesn't do that."

"You, uh, use it whenever someone does something that, like, makes you glad that they did it, I guess. And also when they do you favors or give you compliments or are generally helpful or - I guess we say it a lot? But we don't go around, like, thanking people for not punching us in the face, or whatever."

Nod.

"...sorry."

"Okay, also confused about when humans say sorry but I don't think that was an occasion for it."

"Um, when you did something wrong, or when something bad happened to someone and you're sympathetic, or possibly when you are kind of unclear on whether you did anything wrong but you kind of wish your friends didn't have to deal with evidence of you being kind of creepy."

"I mean, I'm the one whose intended career path is 'kidnapper'."

"...I guess that's true?"

"So I think I'd be being kind of hypocritical if I was upset with you because sometimes you want - or don't even want exactly - to make me like you."

"I guess."

Sigh. 

"I just - I dunno. Thanks for holding onto it."

"Of course."

She'll just stop checking it until the text changes, then. She is kind of mad at herself but not entirely sure why. 

He keeps it in a pocket. 

She keeps using Blink and Shelve in combination at the library. She occasionally uses Whisper. She stops using Un-say and also ends up talking to people markedly less in the first place. She doesn't use All's Well at all. She works really hard at the cemetery.

She kind of talks to Connor less, outside of reading, and talks less about the stuff they're reading afterwards. She doesn't mean to, but it happens. She prints out lists of everything that she and little Connor need for school in the fall, and takes him shopping to buy it. She plays with Zana some. She periodically heads to the fairy ring and reads stacks of books there by herself. It's easier not to hate herself when she's not thinking about herself at all.

"It changed," he tells her a couple of days later.

"Can I see?"

"Yeah. Here you go."

She checks the spellbook.

Spell: Invisibility

Do you need an explanation?

Instructions: Go somewhere where no one can see you. Stay there until you cannot see yourself.

"It's an invisibility spell."
