The week-long national syndication window opens for the 140th episode of Star Trek: Deep Space Nine. William Sadler (Roswell, Bill & Ted’s Bogus Journey) guest stars. This episode introduces the Starfleet black ops division, Section 31, which becomes a recurring feature in the Star Trek mythos, reappearing in Star Trek: Enterprise, Star Trek: Discovery (and the Section 31 spinoff movie), and even the 2013 movie Star Trek: Into Darkness.
