"...why?"

"Well, humans in general aren't. And they have come up with some quite clever ways to deal with this fact, two of the most persistent of which being the existence of an afterlife and the opinion that 'death is a part of the natural order of things.'"

"...but natural orders of things are often terrible."

"Yes, you won't see me agree with this line of reasoning. For whatever reason living your life out to the fullest and accepting your death when it comes is a sort of virtue or something, I'm not sure."

"Weird."

"Yeah. At the same time there is very active research in life extension, medicine, curing diseases, getting rid of cancer, that sort of thing. So it's like, accept your death when it comes to you, but try to delay it as much as possible. Or something."

"...so they'd like healing and de-aging just fine but not something to make them outright immortal?"

"Healing, yes, but I expect lots of people would probably object to de-aging, too, on the grounds that ducked if I know."

"...huh."

"Humans are weird," she shrugs, then looks at the screen. "Fairies are weird, too, in a different way. I guess that just means people are weird."

"Yep."

"Anyway. Guess this about wraps everything up. Do you know of a library nearby?"

"Not trivially nearby but accessible, yes."

"Cool, then, we—oh, there's also the library Mum used to go to, doesn't need to be one close to the tree."

"People there are more likely to know of Thorn and take personal interest in what happened."

"Is anyone there likely to be friendly towards Thorn?"

"He didn't antagonize his neighbors. He traded me to Yellow, say."

"But surely people knew about what stuff he did? Or did he keep a lid on it?"

"He's unusual but mostly in finesse and sadism, not repertoire."

"Yyyyyep, I definitely want to fix that."

"What are we going to do about the other people loyal to Thorn, torturers and such? Sparrow them, too?"

"Yeah. I can do some of them myself, they didn't all have my name."

"We're gonna end up with a menagerie of sparrows that hate us."

"Yup."
