Recap / Star Trek Deep Space Nine S 07 E 13 Field Of Fire
The newest Dax meets the outcast Dax
A serial killer has appeared on the station, and he seems to be using chemically-propelled projectiles, aka bullets, to murder his victims. Ezri is put in charge of the investigation, but she can't make heads or tails of the case. It takes a killer to catch a killer, so Ezri is forced to recall the deranged psyche of Joran from the depths of the Dax symbiont. With Joran's help, Ezri starts to find clues, but at the cost of her own psychological stability... and the killer is already working on finding his next target.

Tropes in this episode:

  • Abnormal Ammo: Zigzagged. In the 24th century, with phasers and disruptors the weapons of choice, bullets are now the abnormal ammo!
  • Artistic License Military: Early in the episode Ezri refers to the first victim, Lieutenant (JG) Ilario, as "not the first drunken ensign I've escorted home" (presumably in reference to Sisko). Funny thing is he's correctly referred to as "Lieutenant Ilario" in the previous scene.
  • Bat Deduction: How Ezri concludes that the killer is a Vulcan, just by discovering that all victims have photos of themselves smiling in their quarters.
  • Catapult Nightmare: Ezri in her nightdress.
  • Cold Sniper: They don't get much colder than a dispassionate Vulcan.
  • Consulting a Convicted Killer: An odd variation in that the killer is inside Ezri.
  • Continuity Nod: The Grissom was the ship destroyed by Kruge in Star Trek III: The Search for Spock.
  • Deconstruction: Of the "emotionless, pure logic" of Vulcans. Vulcans do have emotions, and they are much more powerful and destructive than human emotions. This episode explores what would happen to a Vulcan with severe PTSD when they decide to take extreme measures to contain their emotions. In this case, Chu'lak was experiencing emotion when seeing pictures of people laughing, so "logic demanded" that he destroy the source of them.
  • Enemy Mine: The situation forces Ezri to seek the assistance of Joran.
  • Eureka Moment:
    • O'Brien figuring out how the killer enhanced the rifle to kill from across the station.
    • Ezri realizing that all three victims had pictures of smiling faces in their quarters, and another one when she deduces that the killer is a Vulcan.
  • Exotic Extended Marriage: The Bolian victim has a wife and "co-husband," whatever that means.
  • Fatal Family Photo: Ilario's is actually of friends rather than family, but him smiling over it is one of many warning signs that he's about to die, and the other victims have similar happy pictures near their deaths.
  • Flanderization: Continuing from "Facets," Joran has gone from emotionally unstable with anger-management issues, to outright psychopathic killer, with whom Ezri consults on the murder investigation Hannibal Lecter-style.
  • Gun Accessories: The exographic targeting sensor and micro-transporter.
  • Helpful Hallucination: Invoked by Ezri as part of a Trill ritual so that she can interact with Joran.
  • I Call It "Vera": When O'Brien hears about old frontiersmen doing this with their rifles, he jokes about calling his tricorder "Sally."
  • If You Kill Him, You Will Be Just Like Him: Ezri is faced with this once she comes face-to-face with the killer. She chooses not to.
  • Improbable Weapon User: The killer seems to be using a transporter-assisted sniper rifle, which is like someone today putting a silencer on a musket.
  • In Vino Veritas: A relatively mild example-Ilario tells Ezri how beautiful she is while he's drunk.
  • Journey to the Center of the Mind: The Joran/nightmare scenes.
  • Locked Room Mystery: Lieutenant Junior Grade Ilario, victim number one, was in his quarters with the door locked when he was shot, and the station computer recorded no entry other than him. When you've got a bullet-teleporting sniper rifle, you can do that kind of thing.
  • Noodle Incident: Whatever happened at that bar on Bolarus involving a younger Sisko.
  • Offscreen Moment of Awesome: Ilario's combat piloting (the reason he's being toasted) occurred before the episode starts.
  • Parting Words Regret: When Lieutenant Ilario asks to join Bashir and O'Brien in the Alamo program, they tell him he can't. After he's found dead, they regret not letting him play with them.
  • Red Herring: Ensign Bertram accessed the replicator pattern for the TR-116 rifle, and when we see him he's being chased by security. Turns out he just collects weapons as a hobby and was on Bajor when the murders occurred.
  • Shell-Shocked Veteran: Chu'lak was one of only six survivors of the U.S.S. Grissom when it was destroyed. The episode explores what a Vulcan suffering from severe PTSD is like.
  • Sniper Duel: The episode culminates with one between Ezri and the murderer.
  • Weaponized Teleportation: The murder weapon is a prototype rifle with a micro-transporter that can teleport bullets in mid-flight, allowing the user kill their target from virtually anywhere.
  • What the Hell, Hero?: Sisko gives Ezri one when she almost stabs the guy she thinks is the murderer.
