"Humans - the kind of person I am - grow up faster."

"I used to be a human but became a demon when I died."

"Technically I think I'm significantly younger than your son."

" - huh. There's a world like ours but in the future? Can I see what we achieve -"

Cam rummages around for photos of Tirion.

He and Nerdanel both start cooing over it. "I need a physics textbook."

"I need a materials science textbook -"

"That's so so many people!"

"I assume your world is different in some ways since in this one Elves can't read minds except of each other and specific other species, so other things might be different too, but Quenya's pretty similar far as I can tell and so on... Uh, the bar over there is sapient and has all publications ever and is good at recommending books if you narrow it down well enough."

Both of his parents are kind of just standing there in shock. 

"Hi, Bar!"

Hello! Can I get you anything to drink?

"...for one thing the lighting is different..."

He picks up the napkin and frowns at it. What does it say? he asks the bar -

And then oooh, yes, I would like a drink, thank you!

"Can I have my complete publications in the universe that's hundreds of Years ahead of ours? And Fëanáro's -"

"And Rúmil's and Aulë's and Erulastëon -"

Some paper and some definitely not paper appears! Tiny Maitimo gets a white beverage in a mug!

They blink at it.

" - I guess you're not even ahead of us, yet - Cam, when do they get electricity - wow, my alt's life must have been fascinating - uh, those are computers, my father will tell you the things you need to know to make sense of computers from a not-yet-at-electricity standpoint -"

Looking... "Looks like 1310?"

"That's eighty-five Years from now - what's electricity -"

"I think I like Elves better when they're on even ground with us! Though wow this is so weird - wait, how do you have the chips and not know what electricity is -"

"Chips?"

"Non-cyborgness would explain the different mindreading, they might not have chips."

"- do you, like, die -"

"Very rarely."
