It's a shame that Crusade was cancelled when it was. Everyone's favorite Psi Cop, Bester, was to make an appearance in "Value Judgments", the next episode that would have been filmed had the series not been cancelled. This episode would have been followed up by "To The Ends Of The Earth", a "Signs and Portents"-type episode that, along with the season finale, "End of the Line", would have sent the series into an entirely new direction. Apparently there was much more to Straczynski's 5-year plan for Crusade than just finding a cure for the Drakh plague.

Although the scripts for the episodes mentioned are no longer being sold, has more information, if you're interested. (Look under Crusade, Reviews)
