He also tries very hard not to think about how all of his alts have killed someone. This time, he's not as successful. Edarial's not sure if Prime's killed someone before the fiasco that was finding him, so he might be absolved for that, but the other two certainly chose to. Neither of them regret it in the slightest. He knows this because he asked, quietly, privately. It was in the defense of their matching Bells. That's - he doesn't know how to feel about that. That's worrying.
Obviously, the solution is math. He asks both alts for their - mental numbers, the factors behind them, and then he scurries off to crunch his own and compare with what they have. Iobel didn't want to have a competition, but - this isn't that. He's comparing notes. If he's - likely to kill someone in defense of her, he'd like a heads up first.
Copious amounts of math is completed. Edarial is - kind of frightened by the results. He gets up, and he goes to find Iobel. Because according to Adarin-math, he is probably capable of killing people in her defense.
He glances at the clenched hand. He considers trying to hold it, then - decides against it, for now. Maybe later.
"We've - decided what to do, but we seem to be - having trouble making it - happen."
She lets him, unclenching it as he collects it. She almost says something, but then changes her mind.
"... I have no idea if that was a place to begin or not?" he laughs, self-consciously.
"If you'd walked into my shop and held my hand without saying hello first I daresay I would have been puzzled," she remarks.
"In the scenario where you were acting on instructions from your future self or the one where you have suddenly contrived a need for a spellbook?"
"Both. The - contrived need for a spellbook I would have acted utterly ordinary. The instructions from my future self, less so."
"I think I would have recognized you if you'd walked in. Because you were a prince and it is generally wise to know what the future ruler of one's country looks like. It would have been very unexpected."
"I'll bet," he snorts. "What would you have done if the crown prince walked in asking for a spellbook?"
"Sold it to you. Maybe if I had politics on my mind I'd have asked how you were planning to do some particular thing, if there seemed to be a rapport, but I didn't like to overdo customer interaction, I never liked it when I was held up making small talk while buying jam and bread and sardines."
"Aha. So it might have been required for me to ask for help on, say, a project for a certain fountain."
"I would have been fascinated by the fountain. I'd probably have given you the spellbook for free just to look at what you had on it."
"And you've seen what I'd do with it - although if I'd gotten at the chart in an earlier stage of development I might have been more useful."
"I didn't say I wasn't, but I could have contributed more if there had been more left to do."
"It's huge," she says, and it is. "I'm probably going to wind up pruning it into a few versions, each with its own massive drawback, unless we find alts with magic that handles working memory - I checked Phix's notes on runecasting and it doesn't have anything like that."
