Na'vi and discovering humans having multiple languages

[Neyfan]

Yeah, in all scifi the alien cultures are one, one language and culture. Earth and humans do not have that.

How would say Neytiri react to a human who doesn't speak english at all or as a first language? The Na'vi know english,but not of the thousands of other human languages like German, Japanese, Mandarin, Cantonese, Russian, and so on.

It would be cool and amusing to see this in the sequels. The na'vi meet some of these humans who are non english speakers and how they respond to it.
