I was watching, and I noticed this shady character enjoying what appears to be a nice, freshly prepared lizard on a stick in Downbelow.
How does a lizard whose destiny is to be cooked over a slumdweller's fire get on a space station? I don't think importation is in this guy's price range, nor does it seem like a likely choice if someone were importing food. Does he have a lizard farm in some forgotten cargo bay? But why lizards, and furthermore why the questionable preparation? Surely if you're raising livestock for consumption you'd put more into your prep than "stab with stick, cook, and eat"? Is he going to eat the scales too?
I feel like the only reasonable explanation for this shot appearing in the show is that there are wild lizards on Babylon 5, and this man catches and eats them. I know there are over a dozen canonical B5 novels, but is the idea of wildlife on B5 ever addressed?
