"Repression" is the 150th episode of the science fiction television series Star Trek: Voyager, and the fourth episode of the seventh (and final) season of the series. The storyline revisits the potential for Starfleet and Maquis conflict explored in "Worst Case Scenario" at the end of season three. A series of attacks against former Maquis crew members baffles the Voyager senior staff. This episode explores mind control triggered by a subliminal message and the loyalties of crew members. The friendship between Commander Tuvok and Captain Janeway ultimately overcomes a fanatic's ability to invoke repressed conditioning. A recurring theme is Tuvok's "hunches", which he can neither explain nor ignore. Another feature of this episode is the Vulcan mind meld being used to force or invoke uncharacteristic behaviour. It is unclear how many of the former Maquis crew members on Voyager had been exposed to the fanatic's mind control techniques. This may be a rare instance of a forced mind meld creating aberrant behaviour in the victim. This is also the only onscreen mention of the name of Chakotay's Maquis ship, the Val Jean. Plot A Bajoran man talks to an image of the starship USS Voyager and chants incantations, as images of Voyager crew, formerly Maquis, appear on his screen. On board Voyager, Tom Paris and his new wife B'Elanna Torres enter the holodeck recreation of the Palace Theatre in Chicago to watch a classic film. As the film starts, Tom deletes the holographic audience, revealing Tabor (Jad Mager), comatose in the front row. The Doctor finds disruptions in his synaptic pathways, contusions and microfractures. Captain Janeway puts Tuvok in charge of the investigation into the attack. Tuvok's uncharacteristic "hunch" is that someone on Voyager is responsible. Soon there are five comatose crewmen in Sickbay, with the same injuries, are all former Maquis. Tuvok notes that the assailant must have access to security protocols. Chakotay cautions the other former Maquis: they are to carry hand phasers and go nowhere alone. Meanwhile, Tom Paris and Kim have captured a displaced photon negative image of two humanoid figures on the holodeck – Ensign Tabor and his assailant. Tuvok asks them to increase the resolution of the images and keep him informed. The attacks began after the last data stream from Starfleet, so Tuvok investigates personal messages in that transmission, including a letter to Kim mentioning a friend killed by the Maquis.
