" - I don't have a way to write it." She seems kind of vaguely embarrassed about this. 

"Well, we'll adapt the Elven one."

"OK. Can you, uh, show me how the Elven system works? And I can show you how to write Confederate One?"

Bounce bounce bounce bounce - "That sounds great!"

Awwww. "OK!" She - kind of really wants to eat something but that sounds kind of annoying and surely he's going to eat food at some point?

She can show him how Confederate One looks on paper and show him how it looks with hand signs and describe how it looks with lights, when the Alteri communicate with it.

He is so delighted about this. He gets to work rigging something up that will display the lights on a screen in response to his thoughts. And he shows her the Quenya alphabet, with a symbol for each sound.

Oooh. She works on memorizing them for a bit and then doesn't know how to write them down so she'll remember them and can study them later. After a bit she settles on writing various Etra La words in the Quenya alphabet, one associated with each letter, with Confederate One translations next to them so she doesn't get confused or forget which words are which.

She writes her name, and writes the Confederate One for 97816 next to it. That isn't really the same thing at all, but it'll remind her what that one is.

He may not need to eat; it's mysterious. Anyway he asks questions until he can do the writing and the hand signals.

Well that's terrible, but she's just going to tough it out and hope her memory doesn't suffer very much from the lack of food. (It will. Oh well. She has notes.)

She is happy to answer any and all questions about Confederate One. It's structurally similar to Etra La, in terms of how the words fit together grammatically, but the languages have been diverging for at least a thousand years and at this point they're also fairly distinct.

Oh awesome! In that case he wants to do all the things with Confederate One that they did with Etra La - starting with a small vocabulary list, guessing sentences and eliciting corrections... in addition to not eating it may be that he doesn't sleep.

Oh no.

She can go about eighteen more hours without food or sleep or water (or bathroom breaks, she hasn't had any water since this morning so that happens not to be pressing either), and then her comprehension is going to start to falter. She's not going to bring any of this up before then. Talking to him in her own languages isn't a particularly mentally taxing activity, but she can't actually do it indefinitely.

He has Confederate One down in less than eighteen hours and then does think to ask if she wants to grab food or anything.

Oh good.

"Yeah! That'd be great."

"What do you like?"

"I - like food?"

Aaaaaa.

"Yes, but what kinds of food?"

"Uhhh. I - will tell you when I've had some different kinds of food?"

He laughs. "Makes sense!" 

Someone brings them a spread of lots of kinds of food.

Oh wow that's a lot of kinds of food and she is so hungry. Not dangerously hungry, she knows what that feels like, but pretty uncomfortably hungry.

She focuses kind of a lot on eating at a speed that suggests that the food is tasty but that she is not a starving animal. She offers opinions on various foods, which mostly range from 'this is perfectly fine, I could live on this' to 'this is the best thing I have ever tasted, ancestors, if I ever have to go back to nutrient blocks I'm going to cry'.

He delightedly gets food-specific vocabulary and promises that her favorites will be conveyed to the chefs.

If she were less hungry she would think that was kind of weird but she is so hungry and it's so good. And she offers all of the food-specific vocabulary, though her food-specific vocabulary is a little limited by the fact that a lot of her food for the past ten or twelve years has been nutrient blocks and the occasional vegetable.

That's appalling. The poor people. The Elves will prepare feasts for them for after the Alteri have been reasoned with.

She finds this incredibly gratifying. She's also getting pretty tired, but if Fëanáro isn't going to bed then that must mean they have more to cover. She has ever worked two fourteen-hour shifts without sleeping in between, and it was miserable and she hated it and she was screaming internally by the end but it didn't kill her so hey that's something.

"We can start on Yahivi or we can do location names and geography and star charts and stuff."

"Let's do Yahivi!!"

Oh boy.

"OK!"

They can do Yahivi the same way they did the other languages. Yahivi is structurally and phonetically very different from Etra La, and has a different history underlying it.

She has maybe a few more hours in her before the comprehension problems and limited attention span start getting obvious enough that she can't reasonably cover for them.
