The different beams are now all bent towards a single point to create a three-dimensional sculpture of light hanging in the air in front of her as they constantly cross each other's path. The floating diagram shrinks down from three feet in diameter to a measly six inches, and she twists her head to flash you a smile. "Watch this. Fire in the hole!"
A hole forms in that cage of warped space. You know this only because the lasers race out as a widening cone of burning light, and the resulting carnage puts her particle cannon to shame. You blink in shock at the callousness you just witnessed as sweet little Vista kills the team of mercenaries attacking you, but then you hear it.
Groans of pain. Those henchmen are, somehow, still alive.
"I'm not a Tinker, obviously, but it's funny the kinds of things you can learn from them," Vista says as she deactivates her shield, either aware of your surprise or just wanting to brag a little. "Kid Win? Lasers were about the only things he could build reliably and that he didn't immediately take apart again, but he had a lot of trouble with math and stuff, and he was constantly puttering around with all sorts of equations. I was around enough that I learned some of the physics behind them just by osmosis. Then Miss Militia one day tried to teach us how to play pool, and she is phenomenal at bouncing pool balls off the bumpers. It's all about the angles.
"Put the two of them together, and a couple of times Kid and I tried to work on bouncing his lasers around corners and catching them again. The bouncing, not a problem. Catching, now that's harder. I can corral a laser, but keeping it too long in twisted space makes it spread out, and after a while the laser is just a big flashlight. Then again, Kid's lasers wouldn't hurt you if he shot you. They were basically just a strong punch. With these?" She walks into the apartment, her eyes moving around to make sure nobody would try jumping up or out from around a corner. "Either spreading the light out would make it harmless, or it would hurt them but still wouldn't kill them. No matter which, it was something we could use."
