discover, from Tholian slaves left on board, that a Gorn named Slar has sabotaged the ship. Archer, after hearing voices telling him to achieve more fame and honor, decides to lead an assault team and kills the Gorn. Tucker is able to repair the warp drive and the ship then leaves to rendezvous with the ISS Avenger, arriving in time to save it from four rebel spacecraft. Avenger commanding officer Admiral Black comes aboard for an inspection accompanied by his first officer, Soval. After Black refuses Archer's request for captaincy of the new ship, Archer disintegrates him with a phaser pistol. Archer gives a speech to the officers of both ships, saying that they should move against Starfleet and the Empire. Soval and T'Pol meet, contemplating a future where alien species are respected and treated as equals; they convince Phlox to join their movement and sabotage Defiant. As the sole alien allowed to remain on board, he succeeds in disabling the ship's systems. Soval, on Avenger, then attacks, but Tucker disables Phlox and restores power. Defiant destroys its attacker. When Sato and Archer celebrate in the captain's quarters, Archer dies after being poisoned by Sato and we see that Mayweather is now in league with Sato. Reaching Earth on the advanced and powerful Defiant, Sato contacts Admiral Gardner, demanding his surrender and declaring herself "Empress Sato". Production Writing and filming The idea of returning to the mirror universe in Enterprise was first suggested by Judith and Garfield Reeves-Stevens. In "Mirror, Mirror", the tantalus field was used on several occasions and was thought to be a disintegrator. The Reeves-Stevenses proposed that it could be explained that instead of killing its victims, the field instead transported them back through time to a penal colony in the main universe. The Enterprise would then come across the penal colony, meeting Tiberius, portrayed by William Shatner. Tiberius would seek to use the transporter aboard the Enterprise to return to his own universe, but discovers that it has not yet diverged from the main universe and does not exist. The episode would then have explored the creation of the mirror universe through actions by Tiberius and Captain Archer. The storyline was pitched by Shatner, who had worked with the Reeves-Stevenses on the Shatnerverse series of Star Trek novels, to Manny Coto, Brannon Braga and Rick Berman. Berman had already received a pitch by Mike Sussman that
