And eventually the chipreader and associated hardware is whirring away on that.

He goes to check on the small him. "Are you sure there's no one in yelling range?"

"There might be people on the road to the city but my parents' workshops are soundproofed so they don't get distracted."

"Maybe you can hold the door and someone can go interrupt them."

"It makes them sad when you interrupt them."

"I think in this case it'll make them happy." He takes his hand.

He goes back inside.

...Cam does not bother the tiny Maitimo.

The tiny Maitimo beams at him and waves. 

That is painfully adorable. Cam waves back.

"Timothy says my mommy and daddy will not be sad about being interrupted."

"...I speak seventy or so languages depending on how you count," Cam mentions.

" - he will probably find that interesting. And he will want to give me a hug because this place is weird and confusing and I wish I could go home."

"And you can, as soon as we find him, but you need to be really patient at holding the door, can't get distracted. All right?"

He nods solemnly.

And someone goes and fetches a Fëanáro and a Nerdanel.

They are visibly younger! The equivalent of a human eighteen or nineteen, maybe, definitely not the ambiguous-mid-twenties of their non-mindreading alts.

They look at the door. They blink.

Hugs!!!!!!!!

" - what's this -"

"This is a magical interdimensional bar."

" - interdimensional? There are other dimensions? How'd it end up here, who or what are you - you're not Quendi -"

"I'm a demon, my name is Cam, the door appropriates the locations of doors in other dimensions uncontrollably at random but given the presence of someone from the correct dimension in the bar can be maintained indefinitely. There are a lot of dimensions but we've been concerning ourselves with a handful so far."

"- I see." Blink.

"And some of them have alternate universe versions of the same personality." He inclines his head slightly Timothyward.

"I'm a different species but I'm your son. The Bar can notice when people are alternate universe versions of people and also we are acquainted with another Arda with an adult Nelyafinwë Maitimo who is an alternate universe version of me and also this guy is very much what I remember being like when I was four. - You can meet the my-universe version of yourself in a bit, I sent him a message but time runs strangely within the interdimensional bar."

"I'm seven."
