I would argue that point. River and Simon came from a very affluent family, and both used Chinese interspersed into their conversation. In the episode "Safe," their father uses it. (There are some outtakes of the actor who plays their father trying in vain to get the line out... can't remember if that's the version that's on the DVD, or the extended one that's online.)Scott-S said:The lower class people speak Chinese in this universe. It is sort of the low class language.
In any event, pretty much everyone in the 'verse uses *some* Chinese, whether it's as swear words or endearments. I think it's just meant to represent an overall melding of the dominant cultures following the abandonment of "Earth-That-Was."
And, yes, I love Joss' use of language. It was one of the first things that hooked me into the series. I mean, c'mon -- where else are you gonna hear a line like "I swear by my pretty floral bonnet, I will end you"?
Dong ma?
