Mm-hm. See you tonight.

:All right – er, I'll just read the letter to you first, then I can start putting it in code before bed: 

He goes through it. It's short and gets across the points they discussed, without specifying what questions they're answers to. They can't leave Haven and are willing to wait. They need a uniquely identified person at the other end. Name and this kind of description might work, but also, Tadri? Also Bella (he doesn't use her name) needs assistance to read Valdemaran. 

:I could bring it over to the nearby point with Yfandes tomorrow: he offers. :Although, um, I don't know how worried we ought to be about traps or whatever, it might be safer for you to fly but I don't want to cut into your research time: 

I don't know how worried we ought to be about traps either. It doesn't sound too likely? Tadri wasn't a hostile sort of spy as they go and we do think it was an unusual outlay of his resources.

:Right. I can take care of myself pretty well – I'll go in with shields up and everything – and if something does happen, I can call you really fast, or Yfandes can. I...think that's a reasonable level of precautions?: 

That sounds good.

:See you tonight?: 

Mm-hm!

And she is there that night.

Vanyel has been on top of his time management, and is ready for bed. The completed letter is folded up and stuffed in a sturdy leather envelope for transport. 

And she sends him off to sleep.

The next few days are uneventful. Sayshen gently knocks on her shields around lunchtime the next day to ask for some books – a couple on history, and some historical ballads, but also Seldasen's treatise on ethics. Vanyel gets his two days of leave approved, and looks a lot more relaxed when she runs into him at mealtimes. 

Evening of the third day, when she swings by Healers', Gemma has a letter waiting, addressed to her. 

"Thanks!" Teekay, outside, copy, burn, decode, read.

She still can't read all of it on her own, but the gist of the first sentence is clear – Leareth is congratulating her on picking out Tadri as the spy, there are a few more words there, then he's - expressing appreciation that she left him alive and unmolested, something willingness to cooperate. A note about how something sounds workable; something something three days lead time. 

Is her next regular session with Vanyel in more or less than three days?

It's in two. 

If she's interpreting "lead time" correctly that doesn't strictly matter but she's not sure, she just knows what "three days" means. She brings the letter when she goes to put him to sleep that night.

Vanyel reads it through, first to himself and then out loud to her. 

"...I think he likes you," he says when he's done. "He's acknowledging that you had the capability to harm his agent, and didn't, and he's taking that as a sign of non-aggression and good faith. Er, I assume he didn't include Tadri's name in case someone else read your letter – it's not a very secure code – but he says your proposal is workable, I'm reading that as your proposal to use Tadri as a relay. And three days to set up, but it looks like the letter is dated yesterday, so two days from today, but he says to check again the next day if it doesn't go through, in case there was some unanticipated delay." 

Okay. So day after tomorrow I can check for Tadri. Do you want to be there?

"...Do you want me there?" 

It might be useful to have a second mind on the conversation from this end and a native guide in case he tries to snow me about something but I'll be fine if you have other things to do.

"I can be there." Figuring out whether or not he wants to feels impossible, but whether it's useful to Bella is a much simpler question. "Er, I don't know if you wanted to try to plan what we'll ask – not now, I should sleep, but at some point." 

I expect that to change over the course of the conversation anyway. We may hope he's paying Tadri enough that whether we pause between questions is the least of his concerns.

"Sure, that makes sense." Vanyel lies down. "I guess I'm ready to go to sleep now."

Night! And she puts him to sleep and goes to bed herself.

All seems quiet and she is not woken by any emergencies. 

Then at the appointed time, she can get the earcuff, leave the note about working outside, and notify Vanyel.
