Nayoki swarms through after Leareth. 

He takes the Gate down right away, because that was really far and he's fighting not to sway on his feet. :Nayoki, go find whoever is in charge here, tell them I sent you to negotiate - set-command them if you feel threatened, Gate to Velgarth if you need to–:

And spin around. :Matirin. Talk to me. Are you all right: 

He can't tell what's wrong with Matirin with Thoughtsensing, because he's wearing the amulet, but he's got mage-sight and Healing-Sight and Mindhealing Sight, why isn't he responding - 

<I'm trying to let you ->

<You being here is a bad idea, the situation is very delicate, but they had a good reason to arrest me given the information they had and they have my permission to be doing this and everything is fine. Please just give me a day to get this sorted out, or is there some kind of emergency on Earth ->

His thoughtsensing amulet blocks Thoughtsensing from detecting what is going on here but Healing and Mindhealing sight can both pick it up! That's someone morphed Yeerk!

Okay, 'morphed Yeerk' is better than 'actual Yeerk' (presumably from some other planet) but - what - also he can't tell at all if that's Matirin or the Yeerk-Andalite, but it seems more likely to be whoever's morphed as Yeerk since they can just take over. 

:I am sorry but I cannot actually tell if that is you and I worry I do not have time to resolve this here: 

And he crosses the room to Matirin in two strides and starts bringing up an interworld Gate-terminus under them. 

:Nayoki, can you get a message out - interworld to Velgarth if you cannot reach Earth directly–:

<I can ask him to leave if you calm down and promise me you won't hurt him!>

Interworld Gates take annoyingly long especially when he's already really tired. ...Which is arguably a reason he shouldn't be rushing to Gate them out. He can get the threshold ready and then - figure out if he needs to get Matirin out or not. 

:I am not going to hurt whoever it is, I just want to know what is happening and why: 

Nayoki slips back into the room. Very quietly. :Leareth this seems complicated: 

:I noticed. Shield the door please: 

Gate-threshold stable and ready to go, he can hold it like that while he figures out if he needs it.

What can he– oh, right. He uses Fetching and the Thoughtsensing talisman is no longer on Matirin. 

The Yeerk slithers out of his ear and he collapses to his knees on the grass and scrabbles desperately for the Yeerk's body, on the grass, trying to shield it from Leareth, even though that doesn't make sense. His thoughts are very scattered because this was VERY HORRIBLE, definitely the worst thing to have happened to him in a very long string of bad things, and that despite - he needs to tell Leareth that it's fine -

The demorphing Andalite is thinking that the plan was for him to take a memory-affecting drug immediately afterwards so as to not have violated Matirin's privacy and not doubled the potential avenues for every piece of sensitive information Matirin has to leak and he really wants to do that but also this situation seems like it will not be remotely improved by his being incredibly confused about it - 

<Matirin, do you have this under control, do you want me to take the drugs now ->

Twitch. <- right - forgot - yeah, I guess so - I'm sorry ->

<He didn't know> he is in the meantime saying very firmly to some other confused angry Andalites. <He didn't know they were wrong at all, he was furious when he found out, it was too late when he found out, and he didn't know they were dangerously wrong until he got here, he also did not know Leareth was going to show up here, he thought it should be impossible if we were far enough away - can you please get me the drugs ->

<Is there an emergency on Earth> he asks Leareth dully.

:No. I - was very concerned about what happened to you and did not feel inclined to take the message they sent on faith, I wanted to come myself to confirm you were all right - you are in fact - agreeing to this arrest...?: He's so incredibly confused. :Are you all right?: 

No he just had a Yeerk in him and it was one of the people he loves and trusts more in the world and it was still incredibly horrible. 

<I'm fine> he says in a calm, steady mindvoice that reflects none of that. <This has nothing to do with the alliance or any events on Velgarth or on Earth. When we departed for Earth, my father made the decision to give me wrong coordinates for Earth, to give to Nerefir's fleet, because he didn't want - a larger force that didn't answer to him and disagreed with him on how to approach the situation on Earth. He didn't tell me the coordinates were wrong, I found out later, and I was angry.

I learned yesterday that they were - more wrong than I had imagined. Not just far away from the war, actively dangerous, the fleet lost a lot of ships when they jumped out there. I do not know whether my father did that deliberately. I - think I would bet not, though I acknowledge the odds of it occurring by chance to be very small. Anyway, Nerefir was understandably absolutely furious about this and wanted to verify that I had nothing to do with it, which I was happy to agree to because I in fact had nothing to do with it, and - I apologize for scaring you.>

This is all delivered very flatly but his thoughts are still mostly screaming, he feels like he's been - dipped in tar, or something, and it's sticky and everywhere and in the way of everything - <We agreed that Finleran, who I trust, would take an amnestic afterwards, so that strategic secrets could remain so, and for my privacy - can you stop shielding the door, please ->

:Oh. Gods. That - makes much more sense - of course they were angry...: 

He gestures vaguely at Nayoki, who lowers her shield to collect drugs. (And then puts it right back afterward, unasked, because she's feeling very tense right now.) 

:Matirin, I just stole your Thoughtsensing talisman to confirm things, so I know you are not fine, but - I suppose that is not really the point...: He holds it out in his hand. :What are they going to do now: 

He takes his amulet back and puts it on. <Well, now that they believe me that I had nothing to do with it there are still a lot of - things to work out - but I expect that once we've talked those things over they will very grudgingly congratulate me on having won the war and everything. Did you get the Pool ship?>

:Yes. Very unsurprising coup attempt, led by sub-Visser Twelve, for the expected reasons. Cayaldwin cracked the Gift-morphing problem on the way so we had about ten of Nayoki and taking the ship was trivial: 

He nods. <Congratulations. In that case I expect you should go acquire Vanyel and reassure him that I am fine and that this is just how people are forced to do politics when they haven't any magic horses and are not themselves in some deep fundamental sense Leareth.>

Leareth nods. Reluctantly. :I am glad things are - less bad than I expected. In some ways: Worse in others. Could their father really have... Cayaldwin is going to be very upset, he predicts. :I am sorry for - making things more complicated. I thought it had to be about tech-sharing or something and it seemed - very disproportionate and egregious for that. I do understand their response here: Sigh. 

<Yeah. I was upset until they explained, but with context, I think they acted reasonably. And I want to make sure everyone has that context, but - I should sort things out here first. I apologize for worrying you.>

:It was not your fault at all. I will go back and provide what context I can - if that is all right with you, I think it will be better for me to do that than say nothing: 

<Yes, that's fine.>
