In the opening 20 seconds of the episode, there is an Earth Alliance logo behind Captain Sheridan. The caption below says, "Earth Alliance Cortez 901196". The ship he is on is the Agamemnon. However, the name Cortez is used for a different ship in a later episode.
The security guard visibly tenses before Kalain palm-punches him in the chest.
Commander Sheridan finishes his speech, with five minutes to spare, in an empty control center. A command center, on a station where ships can arrive at any time, would not be empty.
