"So how familiar are you with the history of the Earths that aren't mine?"

"Fairly familiar. The point of divergence is the existence of mutants?"

"As far as I can tell so far, anyway."

"Stop me when I hit a wrong US President...Washington Adams Jefferson Madison Monroe Quincy Adams Jackson Van Buren Harrison Tyler Polk Taylor Fillmore Pierce Buchanan Lincoln Johnson Grant Hayes Garfield Arthur Cleveland Harrison Cleveland McKinley Roosevelt Taft Wilson Harding Coolidge Hoover Roosevelt Truman Eisenhower Kennedy Johnson Nixon Ford Carter -"

"Those're all right. Carter had been President less than a year when the Sentinels happened.

"Then you don't have significant historical divergences, looks like - it is really weird how closely history sticks to the script in worlds with different magics and different people..."

"...Did the others have the Cuban Missile Crisis?"

"I don't know Earth history that well, Emma, d'you -"

"Yep."

"Well that's really weird, because it was caused by a mutant in my world."

"There are a lot of things about cross-world similarities that make terrifyingly little sense - Abaddon's Earth had a Revelation at the same time as Cam did it despite Cam and his family not existing -"

"You've lost me."

"All in the files! But, in Cam and Emma's world, like mine, it is possible to summon daeva, and this was a secret until Cam decided to go public with it in the early 21st century. And Abaddon, my world, also has an Earth, and in that Earth someone else went public with it at the same time as Cam did in his world, and the same way."

"Oh. That's very strange."

"You don't say. And all the versions of me have the same name, despite the fact the magic ones get prophetic names."

"Might depend on how prophecy works but yeah."

"Periodically we get curious and bother Bar about it, but it rarely gets us anywhere."

"Why would Bar know how prophecy works?"

"No, no, about how alternate universe versions of people work."

"Oh. In what ways has it failed to get you anywhere?"

"No published works explain the phenomenon, Bar can identify alts but can't tell us how we could do it - when they don't look conveniently alike, I mean, and apparently they don't always -"

"You don't think you could recognize yourself?"

"I could probably recognize anyone, but personal interaction with people is not a very efficient way to figure out if there's a version of you somewhere in the world."

"Didn't Emma check my world for an alt of your brother?"

"Yeah, and that's weird too, you can't conjure for 'married to', you can't conjure for 'likes these things', you can conjure for 'alternate universe version of' - why?"
