Actual languages spoken by characters
OK, it didn't happen to often, but there were a few times where we actually go to hear what the actual languages spoken by the characters sounded like. For instance, in A Human Reaction, we hear Aeryn and I think Rygel speaking as heard by...well, they're not actuallly humans, but you know what I mean.
What i wonder is if there was actually written dialog that spoke, or did they just ad lib? And they obviously arrived at the "sound" of the Sebacean language by simply taking Claudia Black's voice and running backwards. So one would therefore wonder if what she actually said meant anything, or did she just improvise a bunch of gibberish, which they then ran backwards in post-production?
