Karma Houdini: Hudson gets away when Sisko can't bring himself to shoot him.
Subverted years later. By the time the Dominion wiped out the Maquis, Hudson had been killed.
Poorly Disguised Pilot: Averted. This two-parter establishes the Maquis in order to lay the groundwork for Star Trek: Voyager. However, while it establishes the ideas of the show (showing Klingons, Native Americans, and former Starfleet officers among the Maquis), none of the characters for Voyager appear. In addition, the Maquis would end up playing a much more important story role on DS9 than VOY.
That Man Is Dead: Sisko offers Hudson one last chance to rejoin Starfleet, bringing him his uniform. Hudson chooses to phaser his uniform instead.
