Ha, Mike. Skiffyspeak.
B7 = Blake's 7, a British science fiction TV series that aired about -- ye gods -- 40 years ago. Can that be right?
FTL = Faster Than Lightspeed, possible only in fiction.
Mary Jane = I think this is supposed to be Mary Sue. (Austin?) I'll just assume it is. A Mary Sue is a character in fan fiction who generally is an idealized version of the fan herself. The fiction is based on a favorite TV series; it's a way the fan can insert herself into the action and intermingle with her favorite characters. Frequently the hero falls madly in love with her. I've never heard the Liberator called a Mary Sue, but I can see how the label would fit.
