He is watching a 3D printer print something while working on some kind of blueprints on a large screen.

"Hey, would you like your tablet thing back? Seeing as how you can come back whenever."

"Oh, right, I almost forgot about that. Thanks."

Eva runs back up to her room to fetch it, grabs her laptop, then goes back down to the garage and hands the tablet back over to Nick. She'll just sit in the kitchen researching things for a bit.

There are various noises coming from the impromptu workshop. None too loud.

After a while, Nick starts asking occasional questions about whether this or that service or material is expensive or if such and such a thing would sell well.

Eva is happy to look that stuff up!

And soon enough it's time to run to a junkyard. He's worked out an only slightly awkward-looking way to hide his wings. Eva should probably come along to negotiate for the not-used-to-Earth fairy.

Eva is again happy to do so. She's got a couple nearby candidates, and has directions to get there. ... Are they even going to pretend to take a car or something? Presumably they also want some sort of bag to collect stuff in.

Nick has a sack. And he could tolerate a vehicle for appearances' sake if it could be important.

Probably not too important, and if they were to take it it'd just slow them down (unless Nick transported the car with them too, but that just seems kinda pointless). It would just keep up appearances a bit more. Admittedly not really necessary, and it's probably not too weird to walk to a junkyard to get stuff?

(She really can't be bothered to take a vehicle. It was just a suggestion.)

Junkyard-wards?

Junkyard-wards. He has only human levels of being able to tell when people are looking at him, but he can manage a fast descent in an unoccupied alley near the junkyard just fine.

And they can walk to the entrance, pay a scavengers' fee, and look around for whatever Nick needs.

He needs telekinetically yanked-and-coiled wires, little trays from inside catalytic converters, lengths of rubber, the less rusty pieces of steel, spark plugs, oh an intact alternator that's handy...

There's a large variety of stuff here! Eva's trying to look out for anything he mentions, but a few of the things are definitely not things she'd recognize without researching them some more first. 'Rubber' or 'steel', she can help spot that fine.

Do they get everything Nick needs, or will they need to check out the other scrapyard?

They don't need to visit the other scrapyard for the first round of prototypes, but it might be useful later. Time to whoosh back to Eva's house?

Time to whoosh back!

Now that she's not so stunned by it, whooshing is actually kinda fun.

It really is.

...He thinks of a line he just can't resist using. "I can let you feel acceleration, too, pretend to be a rollercoaster. Do you like to ride rollercoasters?"

Eva raises an eyebrow. Well then. "I think the answer would have to be a yes," she says, somewhat teasingly.

He laughs. "Sorry if that was too forward, I just couldn't not say it once I thought of it. But, say, what's your favorite kind of rollercoaster? Fast and smooth, or one with variety?"

"Oh, well that is a question. I think... hm." She makes a show of thinking. "Slow to start off, but then builds? So yeah, variety."

"I'll keep that in mind in case it becomes... Relevant. I wouldn't presume to tell you when you want to ride a rollercoaster, of course."

"Oh, of course. Relevance is a necessary part of any... rollercoaster ride."

Is it clear that the metaphor is being stretched thin?

Clear enough. "Well since the relevance of this conversation is in question, I guess I'll get to work with this stuff. I'll have a shiny thing to show off to potential investors in a few days, tops."

"That sounds like a good plan!"

And Eva can do some baking or something, because fairies are typically paid in food, don'tcha know. They must have a cookbook somewhere.

Well, this fairy mentions that he is going to want to be paid in actual money if he stays and helps long-term. But food is nice, yes.

Tinkering progresses.
