#mimicry

Ok but what if humans were like the intergalactic translator species because of our mimicry abilities?

And then a week or two in, humans present one chap who can just (kind of) speak their language. He's not doing a great job, but he's closer with his pronunciation than any other species so far and his grasp of the non-verbal parts of the language isn't actually that bad
