and recovered sensor data shows a Tellarite vessel firing. With both delegations on board, and accusations of duplicity rising between the groups, Archer considers taking the Andorians to their homeworld. At full warp, Enterprise is suddenly attacked by an Andorian ship. When attempts at communicating fail, Archer demands that Shran intervene — he complies by explaining how to knock out its shields — but the attempt is ineffective. Enterprise is spared only when the attacking ship has to retreat because of a fluctuating power grid. T'Pol then notices that the "Andorian" and "Tellarite" ships have the same energy signature. The alien vessel is then tracked, and it appears to be capable of holographically disguising itself. Shran is unconvinced, and using Talas as a distraction, manages to escape and capture Gral, before order is restored. However, when Archer convinces Shran to examine the evidence, a member of the Tellarite delegation is able to wrest a weapon from Talas, and shoots her. Meanwhile, Commander Tucker, Lieutenant Malcolm Reed and two MACOs beam aboard the ship, only to find it deserted and without life support. Although the MACOs are beamed back, the transporter is damaged before Tucker and Reed can be rescued. They are able to locate an oxygen supply within the ship's systems, but become stranded when the vessel warps away, and make their way to an empty bridge. On Romulus, it is revealed that the ship is actually a drone, controlled by a pilot under the command of Romulan Admiral Valdore, supported by a scientist called Nijil, in an attempt to prevent a regional détente. Production The episode was written by Mike Sussman and André Bormanis. The duo had previously collaborated on several episodes, the most recent of which season three's "Hatchery". Meanwhile, they had written episodes individually, with Sussman writing three episodes so far during season four and Bormanis penning "Awakening". "Babel One" was directed by David Straiton, his third in season four after the second part of "Storm Front" as well as the stand-alone episode "Daedalus". Filming began on November 2, 2004 and lasted until November 10. The first scene filmed was on the Andorian bridge, which had been used in previous episodes but was made to look battle damaged for this episode. Other sets used included the standing sets to represent the Enterprise, as well as new sets showing the interior of the Romulan vessel. The title of
