His sister had a tinker/thinker power that was well suited for artistry. her creations had appearances, holographic light patterns, and caused psychic sounds that changed based on who was observing them. No one had quite the same experience with her work. People who owned these pieces usually had others that envied them. Thus her creations were in high demand.
Some time later she gave him a device in the rough shape of a handgun. The grip was a smooth transparent crystal. There were complex structures that were etched into the surface that framed non-repetitive fractals within. It had ribbon like glass that extended the butt of the weapon there was a wing-like brace for his had to slip through. The rest changed shape as he tried to move it around in his hand. It was jagged from one view, blocky in another, Took the form of a bird in a third but was generally recognised as the barrel. After messing with some of the thinner extrusion he noted it was surprisingly durable for something that looked so fragile, also a bit too girly for his taste.
Um. I should point out, mass-producing Tinker stuff doesn't work, because it's pretty much always incredibly complicated and prone to things going wrong without the correct maintenance, and only the Tinker in question is able to fix it.
Unless I'm confusing superhero universes again, in which case nevermind.
There are exceptions to the rule, however. I believe Masamune is a Thinker who can make Tinkers' plans suitable for mass production, although I could be confusing something along the line; it's not impossible that there's a Tinker who can make things requiring minimal maintenance, especially if it is such a narrowly-focused and minimally-versatile specialty.
Trigger Event: On one such trip and the last one he had ever booked since then, he boarded the wrong flight and arrived early. He had planned to wait at the airport to apologize to the passenger he accidentally displaced (and had to take the flight Brandon booked) but a mechanical error crashed the plane onto the runway. He would never get that chance. In all, thanks to the safety features and rapid response of emergency services, only five people died. But more than five died as an indirect result. The man he had displaced was a surgeon. And because of a single mistake, he'd never save another life again.
That's certainly unpleasant, but it isn't trigger=event material. About the tamest TE was Grue's; he showed up to his mother's house to get her sister away from some thankfully unspecified thing, when his mother's boyfriend got in the way and he beat him up. In short: Implied sexual abuse of his little sister, which due to Grue's* location included an element of fear as he hurried to her, followed by a fight (during which, incidentally, his mother was screaming at him because he was beating her boyfriend to within an inch of his life). And, remember, this is the
most pleasant trigger event we've heard of. Most are more like Taylor's, which involved being locked inside her locker, which had been filled with an assortment of filth that had been festering over Christmas break, for what was probably at least an hour, at the end of which time Taylor had to go to the hospital.
If being near a plane crash that some stranger you accidentally displaced was on was enough for a trigger event, there wouldn't be any normal humans left in the world.
Kevin spent enough time around his sister to know how to maintain her art pieces.
I'm calling BS on this particular argument. Tinker powers aren't something you can learn (although a certain Teacher might be able to "teach" you).
Anyways. 15 minutes to the deadline!
