This section contains a summary of Babylon 5's story arc (the 5-year plotline) up to, but not including, "Soul Hunter." Note that this is chock full of spoilers!
Season One began with "Midnight on the Firing Line," about 6 months later. Lt. Cmdr Susan Ivanova replaced Lt. Cmdr. Takashima as second-in-command; her dislike of the Psi Corps became evident when Talia Winters arrived. A Centauri agricultural outpost was attacked without provocation by the Narns. (In broad strokes, this episode portrayed the Narns as the "bad guys" and the Centauri as comic relief.) Luis Santiago was reelected President of the Earth Alliance.
