G'Kar offers Londo "spoo", and proudly declares it to be fresh. This foodstuff was first mentioned in She-Ra: Princess of Power (1985). Series creator J. Michael Straczynski was a writer on that show. In this show's universe, spoo is a delicacy among many alien races, although G'Kar is actually needling Londo; while the Narn eat spoo fresh, the Centauri prefer it aged.
The original title of this episode was "Sabre Rattling." Even though the title was changed, the original title still appears in many of the DVD box sets.
In order to break the ice with Claudia Christian, Andrea Thompson walked onto the bridge for her first scene and said "Talia Winters, licensed commercial psychopath." They became good friends afterwards.
