It's honestly really annoying how she can talk to Maitimo without alerting the other humans, but can't talk to the other humans without alerting all of the elves. Such as, for example, to confer with the woman who speaks twelve languages about what they are going to say if it turns out that they are expected to say things to the king, because somehow she kind of expected that they would go to the palace and just sort of look around and get a feel for why people went to the palace, even though in hindsight she can see that wandering around with a local prince with the most functional existing members of the tiny baby polity that you sort of founded overnight on the border of an existing polity is absolutely the sort of situation in which you probably get told to speak to the existing polity's king, even if you were not previously sure that you had anything to say to him.
She checks on the other humans. They look like they're about to sink into the floor. So no letting people ask questions of them, if she panics she has to pass to the woman who speaks twelve languages until she composes herself. Not that she'll be able to tell, since the king probably doesn't speak English and will therefore be using osanwe, but - whatever.
OK. Think Karen. You have seen historical dramas before. What would a vaguely competent person - don't picture yourself, picture, like, Marco Polo or someone - say to the king of the power that you founded your own settlement in the shadow of. Probably he'd introduce himself, give a short summary of events if asked, thank the king for his people's hospitality, and show interest in various things about Tirion. Probably discuss her people's priorities only if asked, since she does not, actually, need any immediate help from the king, and doesn't want to imply that she does. Solid. She can do all of that. It would be less pathetic if everyone weren't going to be reading her entire mind the whole time, but she can't do anything about that, can she.
