* GrowingTheBeard: Sadly averted. The written but unproduced mid-season episode "To The Ends Of The Earth" would have been to ''Crusade'' what "Signs And Portents" was to ''Series/BabylonFive''.
* HoYay: A fair amount of it between Galen and Gideon over the course of the series. Starting with Galen getting himself in trouble with the order for saving Gideon's life in the first place, and, well, this scene in "The Memory of War" sums up the rest:
-->'''Galen:''' Look [[FirstNameBasis Matthew]], to those of us in my order, another Technomage is the only family have. After I was asked to leave the order as a penalty for having too much contact with the outside, I came to rely on you.
-->''(Gideon gives Galen an odd look)''
-->'''Galen:''' [[VerbalBackspace And... and on the others.. and on this place.]]
* RecycledPremise: It's basically ''[[SpaceBattleshipYamato Space Battleship Excalibur]]''. The [[WhatCouldHaveBeen planned five-year arc was going to be]] more like ''Series/BlakesSeven''.
