To the considerable alarm of the nearest Elves, who draw weapons!

She clutches her baby and drops into a crouch around her, squeaking.

Don't move, instructs an Elf, and some of them warily step closer, swords drawn, and if she's listening there's some kind of warning going out.

She shivers and holds very still. Don't hurt me don't hurt my baby please

...Elves start singing. 

It's probably magical.

Can she tell what the song is about?

Sleep!

Okay that's pleasantly nonfatal. She hugs her baby.

They sleep.

She wakes up in a dungeon, nude, her legs but not her arms shackled to the wall. The baby has been clothed in some kind of Elf fabric, light and gold and excessively pretty, and tucked back into her arms.

...she hugs her baby.

After a minute an Elf comes in. 

Do you speak any Quenya?

"Yes."

He raises an eyebrow slightly and someone outside starts softly singing a different song. Hard to guess what this one does.

"What are you doing here?"

"I don't really know. There was a - thing -" Looked like this. "- walked into it, showed up in your city."

"Were you instructed to do that?"

"No."

"What instructions are you currently under?"

"Uh, I was in the middle of acting in a hallucination at the time, so - to do that."

"Do you know how to give someone access to your thoughts?"

"Yes."

"I think you should do that."

"- okay."

Thoughts are art, all over her, on display. Why did the snake monster lead to an Elf city? Why was there even a snake monster? She doesn't know which city this is, they looked like Noldor but the Noldor haven't been here that long by out-of-Angband time. Maybe they are just very very fast at building cities. The baby's (Kat's) clothes are soft.

"Have you lied to me about anything?"

"No."

"Why do you suppose the Enemy wants you here?"
