Yeah, that's one thing I've kind of slated in as a B story in a given
episode...an alien comes aboard and they just can't quite manage to
communicate, it's just too damned foreign in its thinking. (What I'd love is
for them to find out at the end that it's some other alien's damned cat or
something, and they've been spending all this time trying to communicate with
something that ain't sentient...but with aliens, how can you tell sometimes?)
