YMMV / Star Trek: Deep Space Nine S01E19 "Duet"

• Alternative Character Interpretation: How accurate was Marritza's impersonation of Gul Darhe'el? Since the man is dead we know nothing about his real mannerisms. Given Marritza's own trauma, he was likely acting the way he thought Gul Darhe'el was on the inside.
• Anvilicious: The episode's aesop is not presented subtly. Tropes Are Tools, of course, and Nana Visitor makes an entire performance of that line: the viewer can practically feel the Heel Realization set in as Kira hears the words coming out of her own mouth.
• Award Snub: Harris Yulin gave one of the most knife-twisting, heartwrenching one-off performances in the history of Star Trek (and in the face of not even liking the part as written), and he wasn't even nominated for a Guest Star Emmy.
• Crosses the Line Twice: The "Gul Darhe'el" rants about "killing Bajoran scum" cross the line from reprehensibly evil to deliciously evil. Marritza really is playing it up just a bit too much, and it's inferred that this helps to make Odo suspicious.
• Ensemble Dark Horse: Marritza may be one of the most heartbreakingly complex one-shot characters in Star Trek history, and he often shoots right to the top of fan lists ranking them.
• Growing the Beard: Several critics have suggested that this is the point where this happened to DS9, as this episode showed what new and different stories could be done with the series' unique setting.
• Harsher in Hindsight: Marrtiza's thoughts on Cardassia's denial about their imperialism and that his people are all guilty are prophetic in hindsight given how Cardassia will exit the series. Garak will even call back Martiza's thoughts in his final scene.
• Heartwarming in Hindsight: If not for her experience with Marritza, Kira probably doesn't overcome her prejudice of Cardassians. In the long run, this made her more willing to help the Cardassian revolt against the Dominion six years later. So Marritza's actions were not entirely in vain.
• Narm: When "Gul Darhe'el" finally outs himself as Marritza, he does so with an overwrought cry and burying his face in his hands. A less astute viewer might assume he's still in-character and just mocking Marritza with a fake, exaggerated cry... until he continues talking.
• Narm Charm: The above scene still manages to be utterly heartbreaking.
• Tear Jerker: The Reveal combined with the Cruel Twist Ending makes for one of DS9's greatest tragedies.
• The Woobie: Marritza couldn't stand living with how he witnessed the brutalities against the Bajoran people without doing anything to stop it.
