"Like, it's not as strong, and--If I were to, say, take an apple, and put a thin barrier to bisect it, the top and bottom halves wouldn't come off, the barrier and the apple would be sort of coexisting. And then when I dismissed the barrier the structural integrity of the apple where it had been would be severely compromised, but it wouldn't be cut."

"But you could still seriously injure somebody that way?"

"Theoretically, but I never have. I can think of one instance in my whole life so far when I would have chosen to, and I didn't have them at the time."

"Why didn't you have them?"

"When you reincarnate, your S-Factor has to be reactivated. I never actually knew for sure as Beatrice that I still had S-Factor, and almost all of the ways guaranteed to activate it will seriously hurt or kill you if you don't."

"Like Lorica's world's trigger events?"

"Not exactly. If you wander close to an otherwise-lethal source of radiation you may not even know it until you get mad and suddenly your asshole ex's eyebrows are on fire."

"...True story?"

"Hypothetical example, alas."

"So what does it besides lethal radiation?"

"Just say no to exploding exotic energy," murmurs Lorica absently, punching a random-looking array of holes in a bit of sheet metal.

"The shrapnel from the gun's casing did some damage," she tugs the collar of her shirt down to show a thin white scar tracing up her collarbone, "but since we had dormant S-Factor to activate the energy didn't hurt us at all."

"Well, that looks sort of superficial, I hope it doesn't predict the weather or anything? We can be kind of careless about injuries because we can heal each other - and we strongly suspect that if only one of Alli dies she just reintegrates into the other one, although fortunately that hasn't been tested."

"Risked it a little wrangle people into an orderly line for Bella to teleport back when we were doing evac. One of me would do the eating and sleeping and the other would shout at refugees. Could've blown any minute."

"Could you have covered an area all the way around Yellowstone National Park for several consecutive days?"

"The ash robot will mostly only be able to cover a neighborhood-sized area and probably shouldn't operate under the high temperature likely around the middle of the explosion. I could make a bigger one but it might not fit through the door."

"I don't fully understand the meteorology involved but I think apart from being unpleasant to breathe the big problem is that it's getting between us and sunshine, or more to the point our plants and sunshine. If you could just blow a lot of ash in such a way that it would settle, ideally in one of the now-uninhabited parts of the world, that could be big."

"Oh. That's easy. Especially if...the bar arbitrarily conjures objects, right? And you mentioned borrowing things...can I borrow something and take it into her world if the door doesn't close at any point and I bring it right back when I'm done with it?"

The price will be added to your tab, and removed when you return the object.

That doesn't present an obstacle.
