A Bajoran woman hires Quark to recover an item on Deep Space Nine, which leads to the reopening of an old murder case, from the days of the Occupation, involving Odo, Gul Dukat, and Kira Nerys.
- Age Cut: Odo realises the place Quark was breaking into used to be the chemist's shop owned by the long-deceased Vaatrik. He unlocks the door... which opens on Gul Dukat, waiting for Odo in the chemist's shop just two hours after Vaatrik's death.
- And Another Thing...: Odo even makes a Columbo-like gesture while doing it.
- Anti-Hero: Odo keeps insisting he's not on anyone's side. Kira notes that he'll have to pick one eventually.
- Apologetic AttackerTRAZKO: (about to shoot Quark) I'm sorry.
QUARK: Yeah. Me too.
- Bad Liar: Odo accuses Kira of being one. He underestimated her.
- Big Damn Heroes: Rom averts his brother's Sickbed Slaying with some handy screaming. When he realises Quark's survival means he won't inherit the bar, he starts screaming again.
- Big "NO!":ROM: (screaming in fear)
ODO: It's over Rom! Over! You're a hero.
ROM: I am?
ODO: You saved your brother's life.
ROM: (realizes Quark's bar isn't his anymore; begins screaming again)
- Cannot Tell a Lie: Ironically, Odo's reputation for Brutal Honesty helps Kira escape Dukat.
- Captain's Log: Lampshaded and spoofed in Odo's Deadpan Snarker style (despite his disdain, it eventually becomes a Private Eye Monologue).ODO: Commence station security log, Stardate 47282.5. At the request of Commander Sisko, I will hereafter be recording a daily log of law enforcement affairs. The reason for this exercise is beyond my comprehension, except perhaps that Humans have a compulsion to keep records and files — so many, in fact, that they have to invent new ways to store them microscopically. Otherwise their records would overrun all known civilization. My own very adequate memory not being good enough for Starfleet, I am pleased to put my voice into this official record of this day: Everything's under control. End log.
- Confess to a Lesser Crime: When she's accused of murder, Kira confesses to sabotage. Note that this would only be considered "lesser" by Odo; the Cardassians would be far more eager to execute a rebel than the murderer of a mere Bajoran.
- Dies Wide Open: Quark after being shot. Fortunately Bashir doesn't settle for He's Dead, Jim.
- Deadly Delivery: The assassin carries a bunch of flowers while visiting Quark. As the Bajoran deputy is explaining that he can't have visitors, the assassin shoves the flowers into his chest to cover his knife thrust.
- Dramatic Thunder: Throughout Quark's meeting with Pallra.
- Face Death with Dignity: Upon realizing Trazko is going to kill him for Pallra, Quark chooses to make a sarcastic quip rather than beg for his life.
- Femme Fatale: Pallra oozes this trope, but it's a Red Herring. The true Femme Fatale is Kira.
- Friendship Moment: Odo points out that it's been over a year since the Cardassians left, and Kira could have told him the truth any time. When she admits she didn't want to risk their friendship, he notes that it might not have to.
- Good Cop/Bad Cop: Sisko and Odo, respectively, when grilling Rom about why Quark was shot. Odo plays on the "fraternal inheritance" motive angle along with the usual Perp Sweating, while Sisko uses family friend connection between his and Rom's sons to "rein in" Odo.
- Insistent Terminology: The Bajoran deaths in the mines are accidents.
- Irony: Odo says that his passion for justice may be his only clue to the nature of his own kind. Ironically their desire for order and security is the closest thing they have to Odo's ideals.
- It's What I Do: In the present, Kira tries to thank Odo for clearing her of the murder charges in the past. Odo shrugs it off, stating matter-of-factly, "You were innocent of the crime I was investigating." In an ironic twist, we later find out that she in fact wasn't.
- Lampshaded Double Entendre: Kira tells Odo she was looking for a job at Quark's when the murder happened. Odo goes to check this out.QUARK: She was showing me her, er, initiative.
ODO: Is that some sort of sexual reference?
QUARK: These jobs are hard to come by. Her credentials were very... impressive.
- In exchange for getting the list, Pallra promises Quark five bars of latinum and her 'personal gratitude', whereupon Quark leers and rubs his ear in an obvious reference to oo-mox.
- Left Hanging: In the end, Kira asks Odo if he can trust her in the same way ever again. He silently starts to gaze downward as the episode fades to black.
- MacGuffin: The list of names is a list of Bajorans who worked as informers for the Cardassians, whom Pallra intends to Blackmail. Her late husband Vaatrik was the contact between them and Dukat.
- Nice Job Breaking It, Hero!: Odo lets slip to Pallra that Quark has survived the attempt on his life, plus the name of one of the people on the list he was trying to steal. When the latter turns up dead, Odo realises what happened and puts a round-the-clock guard on Quark.
- Noir Episode: The episode follows a detective examining a murder, portrays almost all the characters as morally ambiguous, and employs a chiaroscuro visual style previously unseen in the series. It even has as a version of Private Eye Monologue in the form of Odo's log entries, used for the first time here.
- Noodle Incident: Odo doing the 'Cardassian Neck Trick,' which apparently left the entire Central Command in stitches for weeks.
- Origins Episode: Specifically, shows how Odo came to be a security officer on the station, and met Kira and Quark.
- Private Eye Monologue: As mentioned above, Odo's Captains Logs turn into this gradually over the course of the episode. By the fifth act, "Security log, supplemental" isn't even mentioned.
- Revealing Cover-Up: Granted, Quark likely would've tried to do something unscrupulous with the information he got from peeking at the list, but trying to have him assassinated put Odo on the case.
- Right Behind Me: Odo is interrogating Quark.ODO: She paid you for an alibi? I wonder how Gul Dukat will react when I tell him about that?
QUARK: (looking over Odo's shoulder) I'm sure it'll cost me a case of Cardassian ale.
DUKAT: Two cases at the very least.
- Sherlock Scan: Odo can tell Vaatrik's 'grieving' widow hasn't been crying as the skin around her tear ducts isn't swollen, and knows Kira is lying about working in the mines because her hands are too smooth.
- Ship Tease: While doing his Private Eye Monologue, Odo says that justice is meant to be blind; that there's no room for loyalty... or friendship... or love. Cut to Odo interrogating Kira.
- Smarter Than You Look: During the theft, Rom demonstrates several techniques that leave Quark stunned (largely because Rom previously used them to get into the bar's store room and vault). On the other hand, while getting grilled:Odo: You're not as stupid as you look.
Rom: I am too!
- Standard Female Grab Area:
- Dukat grabs Kira this way in one of the flashbacks and she submits to it silently. Considering that he was in a position to have her executed with a word, he probably could just as easily have restrained her with a finger.
- Kira then grabs Pallra this way when hauling her into a cell. She yanks her arm away angrily, but Kira just lays an even firmer hold on her.
- To Be Lawful or Good: Odo's dilemma in the flashback: trying to keep "order" while the lawful authority is a brutal occupation. While he chooses not to expose Kira's resistance ties to Dukat, that's only because he's convinced she didn't commit the murder."If you're innocent, you'll go free. If you're not, I'll turn you over to Cardassian authorities. That's the only choice here."
- Twisted Echo Cut: Quark and Dukat are sharing an Evil Laugh when the scene Age Cuts to a group of customers laughing in contemporary Quark's.
- Vorpal Pillow: Attempted on Quark, even though the knife the assassin used on the guard would have been quicker. It seems he planned to have Quark die of "natural causes" quietly and didn't change this plan even though he'd already blown the whole point of this subterfuge by stabbing the guard.
- Whatever Happened to the Mouse?: The ever-pragmatic Dukat told Odo he was hiring him to investigate in preference to the recommendation of his superiors, who told him he should just round up and execute ten Bajorans at random in retaliation for the murder. Odo failed to find his culprit, however; which leaves us to wonder whether Dukat decided to carry out those executions.
- Whole Episode Flashback: Much of this story takes place during the Cardassian Occupation of Bajor.
- You Got Spunk: Dukat is amused that Odo is not afraid of him.
