Deliberate "mistake": Though he moved freely about the station in his environmental suit, Kosh was never actually seen going through a door. He approached doors, but then, sometimes rather disconcertingly, would suddenly be shown on the other side. The reason: look closely and you'll realise his costume was too large to fit through any of the doorways on the set, so in reality the character would never have been able to move around the station.

Visible crew/equipment: When the Ikarran tosses Sinclair into a pile of cargo crates, the commander's stunt double's face can be seen briefly. Submitted by Jean G

Revealing: As Lennier is first setting foot on the station, the same extra rides the escalator in the background up twice, even though we never saw him (nor was there time for him to) come down. Submitted by Jean G

Revealing: Inside Sinclair's mind, just after the knight shoots the fake Garibaldi, he lowers his gun and the end briefly lights up red. Evidently the actor accidentally pulled the trigger on the prop and triggered the light that lets the CGI team time the effects correctly. Note that it is not the gun barrel glowing after shooting, as it is not lit up before he lowers it. Submitted by Gary O'Reilly

Continuity: Before she's succeeded in her effort to move it with telekinesis, Talia's penny reverses itself on the table between takes, changing from tails-up to heads-up. Submitted by Jean G

Continuity: While she stands at attention and the Sgt. Major chews out her unit for fighting, Dodger's hair keeps recombing itself every time the shot changes angles. Her bangs are parted, then solid across her forehead, then parted again. Submitted by Jean G

Deliberate "mistake": In this episode, a simple light frequency modulation enables Sheridan to briefly see the Shadow creatures. But because J. Michael Straczynski decided that this was just "too easy," the technique was "accidentally on purpose" forgotten about for subsequent episodes. Submitted by Jean G

Continuity: When you see Morden's picture on the screen before the theme title, he is smiling, but after the theme title ends, he is in a different position and is not smiling.

Continuity: In "Babylon Squared," it took several hours to reach Sector 14 from Babylon 5. Here, Sheridan and Garibaldi get there in a matter of minutes. Submitted by Jean G

Continuity: At the security meeting, just as Captain Lochley is saying "I agree with Sheridan", she is shown in a long shot uncrossing her arms and starting to move forward. The camera goes to a close-up of her, and she once again is shown uncrossing her arms and starting to walk forward. Submitted by Twotall
