Rachel grinned. "That sounds about right. I don't know the whole science about us, though. I know we came from another place, a long time ago, with a few other races, when there was a big war." She doesn't know if the word 'demon' will mean anything here, have the same weight, but she doesn't want to bring it up, not it or the Ever After or the elves. Not yet. "There are...enzymes in my blood that are different from humans, that make spells and charms work if I mix it with plants." That, admittedly, was dumbing it down, but going into leylines with someone who wasn't a witch, even a really smart kid, seemed a bit chancy.

She blinked a couple times, then shrugs, rubbing another leaf between her fingers to try to get something from the oils. Jenks would probably do better, but she doesn't have him, so she's having to trust her own senses. "I don't know. I haven't talked to anyone named Regulus or Lily. Maybe. If humans where they're from know about witches, probably." Unless they were from before the Turn. Oh God, that'd suck dishwater, to run in to pre-Turn witches. Pearce had been okay, but that had only been for one night, and he'd been on a mission. "Have you seen them do magic here?" Maybe that would tell her, if she knew what kind of magic these other 'witches' did.
