"So something about making people live longer in specific...? What other kinds of things are related to this? "

"I'll try imagining making a phoenix." Incant. "Nope."

"Well, phoenixes are immortal, but they don't make people immortal. There must be something about that."

"Like... what? There aren't tons of ways around to immortalize people."

"I have no idea," she admits.

"I mean, I could make something up but that might foul the results."

"Try it anyway?"

"What was it?"

"Just outright inventing a spell so I could tap people on the head and make them immortal," she shrugs.

"Yeah, I think that's a bit too far-fetched." Pause. "Says the girl who thought magic was imaginary just a year and a month ago."

"I mean, tap them with my wand."

"Yes, I know, and it still sounded far-fetched. This is not a thought I should be having, I come from muggledom, I should not be stuck to old preconceived notions of what magic can or can't do!"

"I don't see any principled reason why an alchemical rock should do it and a wand spell shouldn't be able to, it'd just be beastly hard to come up with."

"Well, alchemy seems to be the only known way to break otherwise inviolable laws of magic."

"Then the rules aren't very inviolable, are they."

"Ergo 'otherwise'!"

"Still, wands are pretty great."

"Yeah, they are." Pause. "And now my brain's thinking of experimentation with new kinds of wands."

"New like what?"

"New cores, combination cores, new woods, non-woods. I wonder if a chip of the philosopher's stone could be a wand core."

"Ooh, combination cores, I never heard of those."

"Yeah! And it could be that they just don't work, but it could also be that attitudes like Mr. Ollivander's are widespread enough that people haven't tried, or not enough."

"Yeah, I haven't even heard of it as a thing that doesn't work."

"I mean, if the effects people ascribe to them are really true, it could even make sense that they react to each other or something, but." Shrug.
