They don't know what part of that he thinks is eyebrow-raise-worthy - they don't know his background, if that's the relevant bit, he's just a guy as far as they're concerned.

...Okay, you know what, he doesn't actually know if their thing works both ways and it seems more important to know how this works than to avoid talking to people. Maybe. Or maybe not. Who knows.

He tries to think at them that he's unfamiliar with telepathy and would like them to confirm receipt of this message.

...if he can't communicate rather than just not feeling up for it that's significantly more concerning, they're concerned. Probably the healer can help with it if anybody can? If he wants to take them-collectively up on the offer of getting him?

He just shrugs.

...they're a little tempted to get the healer even though that was an ambiguous response but, no, it'd be a waste of time if he isn't actively interested in having the healer do things for him.

Well, people will probably keep him in fruit and things as long as he's here, and the river's right there for water, and the tent isn't bad, there's definitely worse places he could have ended up as a result of whatever happened to him. And the offer to get the healer if he's interested in that stands, they don't think anybody's going to mind doing that.

He pushes the fruit away from the tent. He opens his mouth and taps his lower lip with his finger and waits in case someone is going to come observe that he has no tongue.

His interlocutor is curious and then vaguely horrified, and spends a moment wondering how he came to be without a tongue before acknowledging that yeah that sure does explain why he's so thin. Well, purees and drinks aren't that much harder than plain fruit, especially if the tools for them are already set up, which they can do right now - they narrate what they're doing as they do, setting up a covered table a little ways from the tent with a hot plate and blender on it and a sign explaining that the newcomer needs softened foods and that the tools are here to facilitate people providing them. They'll have to bring a template from home for a dishwasher, they explain at the end, and they'll do that tomorrow.

He shakes his head and puts a hand over his mouth.

(Why are people like this! They keep giving him food, which is useless, and not cash, which can be traded for coffee, which prevents nightmares! It's like they think if they bury him in leftover french fries they'll go to Heaven. He really hopes that works out for them but he's getting the impression that the focus on food is really excessive even for people who eat, absolutely no one has complained to him that they're getting too much cash and not enough food.)

They're confused. ...unless he's starving himself to death on purpose which is, uh.... well, he gets to do that if he wants to? The offer of food is open, though.

They take down the sign but leave the cookware, after setting it to be slowly degradable rather than immune to weathering; if he objects to the implied suggestion that passerby might want to offer him softened food he can dump it in the woods or whatever but they're not sure enough that they're reading the situation correctly to want to rescind their attempt at help altogether.

He smiles in what is probably their general direction.

Right. Well. They'll be here for a while and they can keep an eye out for him if he wants to get their attention for anything, but they've done everything that's obvious to try for right now, they're going to go back to what they were doing.
