The Identicards given to Marcus and Franklin are for Jim Fennerman and Daniel Lane, respectively. Their backstory is that they are a young married couple on holiday to Mars on their honeymoon. This is a rare look at human social issues in the Babylon 5 universe and insinuates that by the 23rd century, same-sex marriage is perfectly legal not only on Earth but throughout Earth-controlled space. Same-sex relationships and themes in television SF were not typical at this time. In a 2014 interview, show creator J. Michael Straczynski said that "We didn't make a big deal out of them being married. We played it exactly as if it was a male-female couple being married, or pretending to be married. I think it didn't have much of a fuss about it because it's science fiction, you're expected to be able to do those sorts of things more readily than you can in a mainstream show. But yeah, we were out there in the forefront of these things 20 years ago."
