Crusade

J. Michael Straczynski had completed the script for the season 1 finale before the series was cancelled, an episode titled "The End of the Line". The episode was to have Captain Gideon discover the origin of the hybrid-Shadow vessel encountered earlier in the series: a secret EarthForce project to combine human and Shadow technology. An EarthForce officer would have subsequently revealed that Techno-Mages were originally agents of the Shadows who rebelled, but still use the Shadows' technology. The friendship between Gideon and Galen would have been strained, not only by the revelation of the Techno-Mages' origins, but by Galen's admission that he was sent by the Techno-Mages to find any more leftover Shadow technology, and that was why he'd been helping Gideon in the first place. The episode, and the season, was to have ended with Gideon on Mars trying to expose the EarthForce experiments, only to be shot by an EarthForce sniper.
