"The photo studio is on the floor below this one, and I can see a stairwell in that corner." Point.

"Okay!"  Presumably none of these rooms are Obviously a photo studio, given that Lorn doesn't know what that is, but they can hope?

The rooms are labeled!

That's a no, then!  It's fine, they will ask yet another person.

What's the deal with the photo studio; does it look like they should wait outside the door, is there someone to talk to . . .

The photo studio is further subdivided with paper accordioning barriers. He does get a super weird look when he indicates he can't read.

In the photo studio there is a uniformed person at a desk working on his computer. He looks up at Lornell. "Hello, how can I help you?"

"I'm a slider, I have magic that lets me copy traits and things from other people - like generally physical things, skills, and knowledge, but not episodish memory - and an upstairs person recommended me a registered photo series."

"Can you demonstrate that now before we set up?"

"Yes."  They repeat the hair trick.

The person behind the desk's eyes go very wide. He gets up and comes around. "May I?" he asks, reaching for the altered hair.

"Yes.  - Or, you may touch the hair.  Please without pulling or caressing it."

"I would like to check if it is growing directly from your scalp. I will not do this without your permission but if you don't let someone inspect it closely we won't be able to certify much about the photos."

"Don't be - checking-me-out-like, or hurt on purpose?  Otherwise fine.  I just want avoid miscommunication and upsetness."

"I'm not particularly attracted to you," he says. "I might want to pull out one or two hairs. Is that all right?"

"Yes."

He comes closer, sifts through the hair, tugs one free.

"Amazing," he murmurs. "What is it you need the photos specifically for?"

"I don't know; an upstairs person said so.  I would like help.  People in a park did not help; people at Sarind Memorial Hospital did not help despite I let them drug me for hours.  Where does a slider go?  No one has said."

"Well, as far as I'm aware you're the first slider ever to come here. What kind of help do you need?"

"I don't know.  I don't know anything about here.  Can learn, once there is someone it's okay to learn from.  Probably not you, if you are important and know secret things.  But I have no apartment, no money, no life, no friends.  In maybe a week or less I will urgent need a friend, person who likes talking with me, or I will be very sad and want to do no things.  If that and if permission from very skill people, I do anything, another best in the world apparently, very helpful a credit to Loza!  But how to start."

"...I don't know secret things, that's not really a House of Truth thing."

"Okay."

"What we can do for you is confirm that you seem to have magical powers, and people will believe us because we don't lie."

maybe Lorn will be very sad and want to do no things about not having any friends here yet RIGHT NOW actually

"Okay.  Should I borrow your knowledge of things instead of asking questions?"

"If that won't do anything to me."

"It will not."  What are photos, what's a registered photo series specifically, how will they help?

Photos are a way of recording images, and the House of Truth does photos and then keeps verified records of when and under what conditions those were taken, for example for ID purposes.
