In the opening 20 seconds of the episode there is a 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 5 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.
