It's not much later, in Isabella's room, that she asks:
"So... is Alex really a dom?"
"Uneventful. Lots of sorting my memory out, I think I got a good efficiency jump."
"Mm - does it make any sense if I say I streamlined the metadata by which I call up a memory?"
"Lemme parse that," he says, and thinks for a second. "You made the... associations... or whatever-it-is that's information about which memory is which more organized or easier to read or something along those lines?"
"Times, places, emotions, people who were present, subjects I was thinking about, weather, all kinds of stuff."
"Yeah. If I'm thinking of a particular Tuesday, now that day's noon and four o'clock and so on go inside it."
"It really is! After we take over the world and make everyone immortal and fix everything we need to find a way to share magic."
"Right? I can't wait to figure out what lies at the end of the magic rainbow."
"Yes, you know, all those things no one's found out because no one's lived long enough to."
"Well, there are immortal mages older than we are. We might not make all forthcoming discoveries to be made."
"It sounds like at its worse merely a range and scale problem. Surely if someone focuses on that for long enough they'd be able to encompass the whole world? Or at least a small city?"
"Well - you might not want to actually do that per se because you'd want to filter for consent, you're going to get religious objections and suicidal people and stuff."
