Nod.

Is there any way you can find out what happened to my girlfriend?  I haven't seen her in almost three months, and we didn't exactly part on planned terms.

Well, you could tell me her name and I could see what state she is in at the moment.

Tally Youngblood.

Tiny plastic Tally Youngblood and surroundings.

Patch of woods, campfire.  Two upright figures with short hair and even more face tattoos, in bodysuits.

The guy's expression doesn't much change, although his tattoos ramp their spinning back up.  Not that they've slowed down much since the last time.

Cam pinches out the model campfire.

Thank you.

No problem.

...What do you want?  Out of this situation.

Universal sapient flourishing?

...Nod.

Should we exchange names or is that incorrect to do with your type of magical guy?

Nah, it's fine, but points for the attempt at genre savvy. I'm Cam.

Zane.  Nice to meet you.

Charmed. Were we going to maybe leave, at some point?

I'd want to compose a message to my friends, even if your voice will keep the minder happy long enough for them to finish their trick.

Okay, knock yourself out. He sits sideways in a chair.

Zane is going to spend like twenty minutes with a personal screen, then.

Cam's going to grab the complete published works of the world since, oh, fifteen years before the oil 'splosion thing, and poke around at the news and whatnot since then, though a bit haphazardly since he doesn't know what sources to trust.

Then he'll get stuff starting in 2010, with no sign of Revelation.  There are some news sources recognizable from when he was human.  He comes across several articles about flooding and rising sea levels; it seems like looking at a map would have been illustrative after all.  If he checks the current state of things, Florida and New York City are completely gone, Lakes Erie and Ontario are gone but there are another two lakes around their size down around Virginia-or-so; the mouth of the Mississippi is a multiple-state-spanning bay.  There are similar differences across the globe.

As far as he can tell in twenty minutes, Zane is at least approximately right about things.  Here's a modern history textbook with a table of contents that pretty much matches the description Cam received, and if he checks ones in other languages the content is basically identical.

Wow. What is the current population of the world? How many died in the immediate fallout of the oil explosion and its sequelae?

Less than 300 million.  About 10 billion.

10 billion! There weren't that many people or even that close to it in his 2025! He will be looking at demographic charts at the time Zane's done with his composition.

Wave.  He's already typed, How are you planning to de-collar me, how sure are you it'll work, and how long do you think it might take even if your first attempt doesn't cut it?

Cam hefts the model Mars. It comes apart in his hand into neat quarters. Like that.
