"Does anyone here," Nelen says, his voice coming out too quietly, "speak Anitami -"

One person present can echo Nelen uncannily well but none of them seem to speak Anitami!

Nelen doesn't really have a plan for this situation. He looks between various tall aliens nervously.

They don't seem to be sure what to do with him either! Someone offers a pastry. The one who can imitate him is teaching another one to imitate him. Some other people seem to be arguing but not heatedly.

He looks at the pastry, and tentatively holds out his hand.

Pastry alien looks exceedingly pleased with theirself and hands him the pastry.

...he tastes it.

It does not taste like it is made out of alien proteins and will kill him, if you can tell that by taste. 

Nibble nibble. Tentative smile.

The alien beams back at him. Points at themself. "Faervel."

Nelen points at himself. "Nelen."

If they want to trade more vocabulary it seems like no aliens of any color are inclined to bring him to the alien authorities. In fact some will go off to get more food to try to feed him.

He did not actually arrive on an empty stomach and doesn't know how to communicate that but he will tentatively attempt vocabulary.

The aliens are fast on the uptake and it seems like once he teaches one of them something they all know it. 

They elicit enough vocabulary to ask where his parents are.

He is not nearly as good at retention; he mispronounces what he doesn't forget.

His parents are at home.

Do his parents know where he is? Does he need help getting home?

They know where he is and he thinks he knows how to get home. ...he's an adult.

Oh. He is very short.

They are very tall.

This place is called Brithombar. It is their something-city. They're not sure how to communicate what the something is. An important person is here?

...capital city?

Yeah!

(There really isn't much city. Maybe other parts of it are denser.)

It's very spread out for a city.

They do not seem to think so, not especially! Are his people like orcs, orc cities are tall and mostly only have parks on rooftops.

He doesn't know what an orc is but cities do mostly put parks on rooftops.
