Presently it's bedtime, and Cam goes to his room and Matilda and Jellybean go to theirs and Cam has the chance to ask Grace what on earth she meant.
"Well," Grace says, whispering, "you've been holding off on labeling because you're only fourteen, but people stabilize at different ages, don't they? And as near as I can tell you've been stable for almost a year now. Not on either, but on whichever. I think you're just as likely to get a crush on Jellybean as Matilda and vice-versa, and I don't think it's because you're still undeclared, I think you're just wired that way."
Cam considers this. "Okay," he says. "I can live with that."
"I should hope so," says Grace, and Cam laughs, and he goes to sleep.
He's still on a sleep cycle appropriate to school, so he may be up before Jellybean and Matilda in the morning.
"Well, Renée's pretty laid back about my friends calling her Renée - although if I do it she doesn't like it, I have to address her to her face as Mom - but I have friends whose moms insist on being Mrs. Little or whatever," Cam explains. "All right. Now we know where a locus is for later, let's see what we can do about plants and medicines and stuff. We can keep experimenting on that till you guys are bored, and then you can go do whatever for a bit while I win a million dollars and then we can get really started."
"All right, we can keep doing that until you get bored and then we can go and I win a million dollars," says Cam. "I should probably submit an application thing first so they have time to process it, though. Should we take the bus back home or gate there, d'you think?"
Cam wishes to convince his vitamin to be better at being a vitamin. Ideally, it could supply perfect micronutrients for whoever took it with some sort of time-release so it wouldn't be necessary to have a new one every day for the vitamins that humans can't store effectively, but he'd settle for omitting side effects like niacin flush or some other measurable improvement in the performance. What does his manual have to say about that?
They don't make a lot of progress, and after a while Cam switches to a potato of his own. He already has a fair number of spells pulled on the subject of food and knows how to make the potato taste like chicken. Can he make it have other features of cleverer products? Can it taste like beef, can he fuss with the macronutrient content, will it consent to pass on characteristics like that to its sprouts?
He decides to wait to see if Jellybean gets around to more useful changes than darkened color of his own accord before attempting to prod him into it. He carries on with his own approach to the project, and takes a bit of a listen to what Matilda's doing between attempts.
Jellybean convinces the potato to have a nutrient balance closer to the ideal ratio for human consumption. He doesn't say it like that, though, so it might take some listening to figure out that's what he's up to.
"Yeah. Arizona's not really great for it, but I guess if we can make them take root in the backyard here, that's a good test of how they'll do in, like, the Sahara, compared to if we went someplace cooler?" says Cam. "So there's here, it's not like the sand in the yard is doing anything that Renée'll be annoyed if we mess up."
It'll take a while to get longer term data on how tasty it is, of course. He goes in and works with the next most cooperative item, a grain of quinoa that Renée bought as a form of protein for vegetarian experimentation, and gives it a similar treatment.
Invisibility: check!
Gate setup is a go!
Is that the office of James Randi? Well, there's James Randi, anyway.
Cam steps through.
"My application's under Nick Carter, but full disclosure, not my real name," says Cam. "Oh, and I don't have a bank account, for reasons of my own, so if you can't give the first payment in non-check form I'll just have to skip that one, and I'd like the rest liquidated in cash, and the agreed-upon test was that I'd make some plant seeds of your own provision sprout instantly by talking to them, do you have those ready or do you want me to wait while you send somebody to the garden store?"
"Mr. Carter, are you invisible?"
"Yes," says Cam dryly. "Yes, I am invisible, and I teleported here, but isn't the point that we do an agreed-upon test under controlled conditions, not that I just show up and wow you?"
"...Ye-e-es."
He does not sound thrilled.
"If you want to see some other stuff, to make up for the fact that you're going to have to give me a million dollars and the fact that I've got other things to do than loiter here being researched," says Cam, "I don't object to passing the time."
"What can you do?"
"Lots of stuff," says Cam brightly. "But not manufacture a million dollars out of thin air, which is why I'm here."
"Why so secretive, Mr. Carter?" he asks, after the phone call has concluded.
"I'm not omnipotent, teleporting is kinda hard, and I'm really not interested in a career as a lab rat," says Cam. "I don't think you personally would be cutting me up, but I'd rather your friends and colleagues not be able to find me at home."
"Why no bank account?"
"For," Cam repeats, "reasons of my own."
"Well, I'm still learning, but I can look up any specific effects that interest you."
"So the... magic... you're claiming is in a book."
"I don't really want to go into too much detail, Mr. Randi. There's a reason I'm being invisible and so on."
"I see." Pause. "Can you fix my computer?"
"That's a probably!" says Cam, flicking his manual and turning pages.
Randi side-eyes him and starts poking around on his computer.
"You realize if I can't parade you in front of all of the people interested in the outcome of the challenge," Randi says, "it'll be hard to explain."
"You can film it if you want. I am after all invisible," offers Cam. "I realize that doesn't help that much, given movies, but it should do some."
"A little. I don't want to do too much of it, and you won't be able to prove it's not voiceover anyway."
"True," Randi admits.
His phone rings. He picks up.
"If you'll come with me," he says to Cam when the call ends.
"Right behind you, Mr. Randi."
"Yep," says Cam.
Down the elevator they go.
There are some pots and some seeds in them, and they're under plastic covers.
"All you have to do is talk to them, is that right?" Randi asks.
"I can do it that way," confirms Cam vaguely. "Pretty sure they can hear me through the plastic."
"Go ahead, then," sighs Randi.
"Heyyyy, seeds," says Cam brightly in Speech, familiar by now with how to wake up plants. "Sprout!"
"...We agreed on this test," says Randi quietly. "You've passed this test."
"Yeah, but I don't mind making another trip, I mean, it's a million dollars, it'll take you guys a while to liquidate it anyway, right?"
"If someone else invisible with my voice who hacks into one of our email accounts to get the when-and-where information appears," Cam says, "or rather, doesn't appear, but invisibly comes to be located here, says he's in your records as Nick Carter, and asks for my money, you know what, hand him an installment, I won't blame you," says Cam. "The exactly one million figure does not matter that much to me."
"Yes, please, otherwise I'd have to do something awkward where I teleport to a lot of different post offices redeeming money orders so nobody can tell where I live, they maybe ask for ID, or whatever."
"...That'll take a while."
"I'm not in a huge hurry," says Cam. "Just keep it coming, please."
"As agreed," Randi sighs, picking up a plastic cover and poking at one of the plants.
"You can go," sighs Randi, poking another plant.
Cam strolls out of the room.
"Moon," observes Cam, perhaps unnecessarily, turning on the spot to take in the moonscape. The stars are something else, the view of Earth really something else. "Damn." The part they're standing on is pretty much gray dirt as far as the eye can see, but the sky from here...
