Eva's decorating for a party. It's not commemorating anything special, like a birthday, but who needs an excuse for a party? It's just a regular party, with lots of people, and of course it's going to be great because Eva is involved in the planning and organization. Sitting on the floor, she's drawing geometric shapes nearby, seemingly at random, though they seem to be forming some sort of pattern. Her phone buzzes, so she gets it out and responds to a text, then continues drawing. She finishes the circle she was working on.
".. Of course it is, you used telekinesis earlier. Sorry, this is all a bit... new." She runs her hand through her hair, then says, "Yeah, that'd be good."
"Up so we're specks in the sky, or streetwise and hope nobody notices the weird blur?"
"Uh. I'm fine with specks in the sky." Of course she is. Totally fine.
She realizes that she should probably grab her bag, so she fetches it, then says, "Right, I'm ready to go."
Fwoosh! They're out the door and high, high up without so much as a rush of air or a feeling of acceleration. He hovers for a few moments, pretending to look for the right house. (He's clearly showing off.)
Okaaaay. This is pretty exhilarating, and also very freaky, but kinda scary.
Jackpot. She has hit the literal jackpot, assuming she's not dreaming.
That assumes the fairy can be convinced to cooperate. He's not been too unreasonable so far, at least.
And then with another surreal zoom of motion, they're at the back door of her house with only a little plant-rustling to show for it.
Of course it assumes that. It's not, however, an unreasonable assumption.
She takes a moment to steady herself, then gets out her key and opens the door. "Right, so. You made it sound like you've never had to try to bring a world up to the modern age before. Do you have stuff saved on your... tablet thingy? Like, perhaps, scientific research papers?"
"I was planning to have you unsummon and resummon me, so I could download a library. Getting enough tools to kick-start a scientific revolution is not cheap unless you're willing to risk dealing with a, a particularly dangerous kind of daeva."
"Okay, but do you have anything on you now? I'm a little worried that you're going to disappear and then I'm not gonna be able to get you back. I mean, I have never heard of real fairies, ones like you, ever before."
"...Okay, I do have a ten year old encyclopedia from a hundred fifty years in your future. But if I give it to you maybe you just don't resummon me, and get rich and famous off it not to mention I've just lost a semi-nice computer and all my information security in one go."
"I'm not saying all of it, but if you could somehow get a couple of... I don't know! Research papers? Product designs? Something that would pay off and have benefits for sure, like something that gets water out of the atmosphere into a potable form? Or a scientific breakthrough, if there's been anything revolutionary."
"...Fine, fine, I'll set it up to only show a few things that came out relatively close to 2015 unless I unlock it again with a hideously long password. It'll take a bit of setup, though. The water thing isn't really possible, RO membranes get more efficient but there's real physical limits involved. How about... Instructions for making hydrocarbon batteries and the formulae and synthesis steps for a couple dozen medicines?"
"I think that would be extremely useful, awesome, and is approximately exactly what I was looking for, so thank you!"
She is not literally bouncing, mainly because it would be too undignified.
He starts tapping away on the computer. "I'm an unusually technopathic fairy, by the way, most don't bother. It's traditional to pay fairies with food." Hint, hint.
"Thank you," she repeats. "Is there anything in particular you like? Brownies? We have brownies and cookies, if you want something sweet."
"Brownies sound nice, thanks. I'm not trying to be mean, here, I'm just being careful and part of me can't stop seeing you as an incompetent summoner even when I ought to know better."
"No, don't worry, this is great."
Okay, she should probably stop with the continued thanks and go get those brownies, but even if she didn't summon him back, she would probably be set for life. A couple dozen medicines, depending on what they do, could make her extremely wealthy. Of course, she'd have to find someone to sell the rights to or something, and they'd have to believe that she's not just made everything up, but that is not insurmountable.
Right, brownies! She goes to fetch them.
Tap tap tap, tap tap, tap tap tap. He seems very efficient about it.
"Actually, if you could get me a lot of food to bring back I could buy more stuff. Second computer, a printer, plasma cutter, you know, tools."
She stops. "Okay! Uh, anything in particular? I could run to the store and fetch stuff."
"Cheapish packaged processed stuff, chips, cookies, cheese, meat, beer. Fairies in general aren't likely to notice it's from so long ago."
"I can't actually go buy more beer, since I'm not 21 yet, but I can get you what we already have. My mom, uh, trusts me."
If that's all, she will write that as a note into her phone and drive to a local store to get lots of the aforementioned stuff.
"Oh, right, drinking age is a thing. Beer specifically isn't necessary, it was just an example."
By the time she's back, Nick will be done with his hasty reprogramming.
And she is back with large quantities of stuff. If the de- and re-summoning works fine, he can take it back in batches. "I'm baaack," she says, still being somewhat ridiculously happy over the whole thing.
"Okay, so." He levitates a significant chunk of the stuff in front of him, touching it. "I wrote out a new circle that will get me and only me. When you want to summon me again, draw most but not all of the circle on a flat surface in any material, then write out the script around it, then finish the circle. It'll call me, and I might not answer immediately so just leave it until I do. And I'll need a few hours to exchange all this food for futuretools... Unsummoning me works by wanting me gone for a solid minute."
