Oh.
Leareth starts trying to say something and then gives up and just leaves his thoughts public again. He hadn't thought about it! None of the individual things bother him either! Aside from the fact that he is now noticing there's kind of a pattern here and - maybe he's asking a lot of Maitimo actually, that is a lot of support things for one person to be doing, it seems maybe even unfair but - it's not like there are that many other people he could ask for this kind of help. Maybe he could ask Nayoki to come across from Velgarth, but she's very competently running a research team in his absence and he's loathe to grab any of his best people from the organization when he's not there and won't be for the foreseeable future, and also this would be an even weirder shifting-of-roles for her than it is for Vanyel, probably.
The part where he's formally their prisoner doesn't seem that interesting, Leareth is sure that Maitimo distrusts him exactly the amount he distrusts himself, and that is correct, it's actively helpful at this point that he can offload some of the paranoia about whether and how Melkor compromised him so that he can - focus on doing things at all.
He remembers a fragment that he's pretty sure is real, Maitimo walking in while he lay in the rubble of Angband, looking at him, gesturing for someone to knock him unconscious. It was clearly the correct thing to do. If anything he feels safer, knowing that happened.
...He's worried that Maitimo wouldn't be able to notice if this were an unfair position to put him in, because the entire person he is, is so shaped around being what other people need.
That is a lot of not very coherent thoughts! About a subject he had not considered until now and has no idea how to think about either! Mostly Leareth is grateful that Maitimo is around and willing to spend kind of an absurd amount of time helping him even though he has a lot of other important responsibilities.
