She does not catch it; she has to scoot over and grab it. "How does it UV?"
She closes her eyes, holds the crystal at arm's length in front of her nose - drops her arms and leaves the crystal floating there - and starts chanting in Latin.
"Back when I'm back," she sighs, and she shoulders her bag, stashes the crystal, and tromps away into the woods.
After that time, she comes back. In a black uniform with a name badge that says Witch I. Swan and has one empty pip on the collar. They've apparently allowed her to dispense with the hat. Her companion (Witch M. Roxbury) wears one - black, mesh panel, brimmed - and has two pips, full.
Witch I. Swan dispels her invisibility spell by chanting in Latin some more.
"She's reassured me that she has some reason to think so," M. Roxbury says. "We'd like you to come down to the USADI base and talk it over there."
"Ultraviolet weapons are of strong research interest to us because of their efficacy against vampires. We tested yours on a captive and its results were impressive."
...A captive. Well. "I am willing to share technical documents and by my guesstimate I could build a machine to produce the same kind of UV emitters at scale in a week or two. But I want my property back. Please also keep in mind that I have never visited this version of Earth before, and will probably react to things differently than you expect. For example, killing a prisoner is often considered a war crime."
"Experimenting on vampires is legal and strategically essential," says M. Roxbury, sounding surprised that he'd take offense. "We don't always have one around, but since we did, it was used to verify your story that your flashlight was ultraviolet. At any rate, we have no attachment to the individual flashlight, but our techs been trying to develop handheld civilian-suitable ultraviolet flashlights that produce a strong enough beam to dust a vampire for years."
"I don't doubt your word, but imagine if someone told you they had executed a, say, a religious extremist. That's what I mean by warning you that I might react to things strangely. At any rate, lead the way to the base, or I can fly us all there very quickly if you give me directions and trust me enough for that."
Bella sighs.
"Vampires have no souls," Roxbury continues. "By and large their interests are murder, murder-themed hedonism, and occasional apocalypses."
"I see. In that case I can certainly help set up manufacturing of the UV emitters as quickly as possible, under some conditions. An expedited patent, or perhaps just a large lump sum." Nick follows them, walking instead of floating for solidarity, and to seem less alien.
"What are you planning on doing with the money?" Roxbury inquires.
"I don't have selfish uses for large amounts of money beyond a certain point since it's no good in Fairyland and I can only bring so much when I go back. But I do want the options it provides as long as I'm still on Earth."
"Historically only a handful of demons want money and they usually don't want it for anything nice," Bella says. "You can probably get a better deal if you offer to let the USADI or a representative hold it in trust for you and block you if you start hiring mercenary vampires with it."
"It'd come with a fair bit of bureaucracy, wouldn't it? So that's a 'maybe, negotiation pending'. But I'm not a classic demon. I'll swear under lie detection- my temperament is better described as similar to the so-called neutral species. I have never killed anyone or indirectly caused any deaths- any humans, I should amend, given the test you mentioned. And I plan to keep it that way."
"I'm actually considering assigning Swan as your liaison," Roxbury says. "You're currently need-to-know but everyone who needs to know has a lot on their plate and she can be freely assigned. Too bureaucratic?" asks Roxbury dryly.
