“
Dax's line when she first meets Worf, and its translation, are given in the script as: "DAX (mischievous, in Klingon): Louk, a jeek CHIM‑ta law. (Yeah, but I'm a lot better looking than he was.)"
❕
Spoiler » This contains spoiler information for DS9 5x01: Apocalypse Rising. Come back after you've watched it. Continue anyway » The General Martok in this episode is actually a changeling impostor. It's unclear how the changeling faked the blood test near the start of this episode, but the reality is that the writers at this point likely hadn't envisioned a future episode where Martok had been replaced by a changeling.
Nitpickery: In the opening sequence, the crew are searching for a changeling on board the station. Kira contacts O'Brien and says, "Watch yourself, Chief. This changeling knows the station as well as we do. He could be anywhere, or anything." It is then revealed that this is merely a training exercise and that the changeling is Odo. Kira's warning to O'Brien serves no purpose in this context and acts only as exposition and to heighten the drama for the audience.
Watch Recommendation: Season 4 marks a significant refresh for Deep Space Nine and sets up important stories for the future. This episode is absolutely a "Must Watch" and is the 5th on the "Bare Minimum" list.
After an accident on the Defiant, Jake lives out his life on a quest to find his lost father.
Watch Recommendation: While you could skip this episode and not miss anything that is important to the overall story of this series, this episode is especially good and it's a bit of a step out of the norm for DS9. For those reasons, it's rated as "Highly Recommended."
Bashir tries to cure a group of Jem'Hadar of their addiction. B-plot: Much to the annoyance of Odo, Worf can't help but insert himself into matters of station security.

Worf's RAP Sheet: Interfering in an investigation
Thoughts: Until my most recent watch-through of this series, I never really paid attention to how may breaches of protocol, infractions, and outright crimes that Worf committed in this show. In this episode, we have "interfering in an investigation," but we'll see plenty more additions to his RAP sheet in the coming season and beyond.
Watch Recommendation: It's average and not terribly important. No recommendation.
Kira and Dukat investigate a 6-year-old crash site that claimed both Cardassian and Bajoran lives. B-plot: Sisko becomes uncomfortable when his relationship with Kasidy starts getting serious.
👽
This episode marks the first time in the Star Trek franchise that the Breen are depicted, even though we only see them in full suits and helmets. We will not see a Breen "in the flesh" until almost 30 years after this episode aired, in DIS 5x05: Mirrors.
Watch Recommendation: This episode introduces a new character and an important relationship for Dukat, so it's rated as a "Must Watch."
Dax is reunited with a symbiont from a previous life.
💋
This episode includes Star Trek's first same-sex kiss. This episode aired on October 30, 1995, and the kiss between Terry Farrell (Jadzia Dax) and Susanna Thompson (Dr. Lenara Kahn) was very controversial. Star Trek's first kiss between two men wouldn't be seen for another twenty-two years, in a 2017 episode of Star Trek: Discovery.
Watch Recommendation: The episode covers more of Dax's past, but it is still sort of a one-off episode that isn't going to impact the rest of the series. No recommendation.
The Defiant protects a Karemma ship from the Jem'Hadar in a sort of submarine-type way. Quark must earn the trade minister's trust while they disarm an undetonated torpedo.
Watch Recommendation: It's a good episode but nothing really important happens in it. No recommendation.
On their way to drop off Nog at Starfleet Academy, Quark, Rom, and Nog are thrown back in time to 1947 Roswell, New Mexico.

Episode takes place on Earth
Thoughts: This episode is usually rated by others as being above-average, and I think it's largely because everyone loves a good time-travel Trek story. I'm going against the grain by only giving it 2 stars... but this one just wasn't for me. It's a little too goofy and there some very cringy moments. And I'm pretty sure I got emphysema just by watching this episode. Of all the time-travel episodes in Trek, I'd rather watch any of them over this one.
Watch Recommendation: If you want to see a time-travel episode placed in 1947, don't let my rating stop you. I'm marking this as "Optional."
Kor, Dax, and Worf search for the fabled Sword of Kahless.
🔀
Crossover: Kor (TOS), Toral (TNG)
🔗
Toral, son of Duras, first appears in TNG 4x26/5x01: Redemption, Parts I and II (though he is played by a different actor). In the episode, Worf spares Toral's life instead of killing him in response to his crimes against the House of Mogh.
🔗
Kor speaks of the Klingon Emperor, saying "a clone of the original Kahless cooked up in a vat by ambitious clerics." The story of this emperor is told in TNG 6x23: Rightful Heir.
Watch Recommendation: It's an average episode with not much impact on the rest of the series. No recommendation. Of course, if you want to see Kor again, go for it!
Bashir plays out a spy fantasy on the holodeck when things go awry.
🎭
Comedy/lighthearted episode
🟨
Holodeck episode
Thoughts: Despite my general dislike of Dr. Bashir, I think he's found a good spot here. He's much less annoying as a super-spy than in his role as a smug doctor. This episode requires a healthy dose of suspension of disbelief. Once you set aside the ridiculousness of the setup, i.e. how they got into the crazy holodeck situation, that makes it easier to sit back and just enjoy the hijinks.
Watch Recommendation: It doesn't have any impact on the rest of the series (except for a quick in-joke in episode DS9 6x20: His Way), but it's a fun Holodeck Hijinks episode, so I'll mark it as "Optional." I think it's always fun to see the cast playing different characters.
Sisko is made head of Starfleet security on Earth after a Changeling bombing.

Admiral Pips: Pips are awarded to episodes that are the most stand-out, representative examples of the series as a whole.
Watch Recommendation: This episode and the next episode are very important and integral to the overall storyline of Deep Space Nine. These two episodes are rated as "Must Watch."

Watch Recommendation: This episode and the previous episode are very important and integral to the overall storyline of Deep Space Nine. These two episodes are rated as "Must Watch."
Kira and Dukat chase Klingons in a woefully inadequate Cardassian cargo ship.
Thoughts: At one point, Dukat (played by Marc Alaimo) speaks of a fellow Cardassian, Gul Marratt, calling him "very dashing." This was such a missed opportunity to make a great in-joke. He could have instead talked about Gul Macet, another Cardassian who was also played by Marc Alaimo five years prior, in TNG 4x12: The Wounded. The line would have been much more humorous if Dukat were referring to someone who looks just like him as "very dashing."
Watch Recommendation: This episode is "Recommended" for some character building for Kira, Dukat, Damar, and Ziyal.
Kurn arrives on DS9 and asks Worf to kill him. Meanwhile, Kira and O'Brien investigate suspicious Klingon battle exercises just outside of Bajoran space.
A man who had been lost in the wormhole for 300 years now claims to be the Emissary of the Prophets.
B-plot: After his wife and daughter return to the station, O'Brien misses hanging out with Bashir.
“
Now?! - Worf, reacting to the news that Keiko is having another baby.
🔗
During an emergency on the Enterprise, Worf had to deliver Keiko's first baby, Molly, in TNG 5x05: Disaster.
Thoughts: One thing about this episode always bothered me. Sisko and Akorem Laan enter the wormhole, only Sisko returns, and the Bajorans only have Sisko's word on what happened. Considering the circumstances of their visit to the wormhole, did no one suspect Sisko of... you know, making Akorem "disappear"?
Watch Recommendation: While the episode effectively gives insight into Sisko's feelings about being the Emissary to the Prophets, the story itself doesn't have any impact on the rest of the series since everything is wrapped up by the end of the episode. No recommendation.
Worf's intentions are on trial after he unintentionally destroys a transport full of Klingon civilians.
⚖️
Courtroom Episode
📃
Worf's RAP Sheet: Negligence, assault
🎥
Notable Cinematography: Witness testimony addressing the camera directly.
Watch Recommendation: I like this episode, and you could give it a watch if you like courtroom episodes, but since it doesn't have any impact on the rest of the series (other than adding another charge to Worf's growing list of offenses), I'm not giving it a recommendation.
Dark themes: Mental illness, trauma, murder, suicide.
Thoughts: I really would have liked to see more consequences of this episode in later stories rather than just having everything wrapped up at the end of this episode and never mentioned again. Also, the least the Argrathi people could have done was given O'Brien the replicator pattern for chee'lash fruit :(
Watch Recommendation: Reviews are mixed, and despite the trauma that O'Brien endures, the events of this episode are never, ever mentioned again. No recommendation.
A really creepy woman helps Jake write; Lwaxana visits Odo, seeking help for her unborn son.
🔗
Lwaxana speaks to Odo about her daughter Kestra, who died at age 6. The story of this loss is told in TNG 7x07: Dark Page.
🙇♀️
This is the final appearance of Majel Barrett, as Lwaxana Troi, in the Star Trek franchise. Barrett also played Nurse Christine Chapel in The Original Series and The Animated Series. Lwaxana's unborn son in this episode is never mentioned again, but presumably he was born and is out there, somewhere...
Thoughts: I'm not sure which one is the A-plot and which is the B-plot. The episode seems like it's two entirely unrelated stories thrown together, and neither of them is good.
Watch Recommendation: This episode is dumb. Skip it. Despite the very low score, I'm not marking this one as "Notably Bad" because it is sort of just passively bad, while the other lowest-rated episodes actively cause me pain when watching them.
The crew join forces with the Dominion to find a group of rogue Jem'Hadar.
🔗
The impetus of this story centers on the discovery of an Iconian Gateway. The legend of the Iconians is first discussed when the planet Iconia is discovered in TNG 2x11: Contagion. Worf references this episode when he tells Sisko that he was present when Iconia was discovered.
📃
Worf's RAP sheet: Assault on an ally
Nitpickery: Near the beginning of the episode, Sisko says he wishes he could have the Defiant standing guard over the station "twenty-six hours a day." There are numerous references to twenty-six-hour days throughout the series, so, while it is never explicitly stated, it can be assumed that Bajor takes twenty-six hours to make one rotation and since DS9 is a Bajoran station, that is the schedule this crew follows. So what am I nitpicking? Avery Brooks (Sisko) puts an odd emphasis on the word "six" when he delivers his line, as if he's exaggerating or saying something out of the ordinary. I feel like the line should have been delivered more casually. Imagine if someone emphasized the "four" when they said, "Our store is open twenty-FOUR hours a day."
Watch Recommendation: It's a decent episode, but it's not crucial to the rest of the show. No recommendation.
Bashir works to cure a plague that was created by the Dominion.
🙄
Annoying Bashir Moment: "There is no cure!" Thankfully, Jadzia gives him a reality-check.
Watch Recommendation: It is one of my favorites to watch, so I have to admit that Dr. Bashir doesn't always bother me. Still, it is a one-off story that is not important to the rest of the show, so I'm not giving a recommendation.
After learning that he has a terminal illness, Quark sells his soon-to-be dead body to the highest bidder. Also, Kira becomes a surrogate mother.
Watch Recommendation: I originally had this rated as "Recommended" because of two plot developments that you probably should know about, but the episode isn't really that great... so you can either watch it yourself, or just see those two things by clicking on this spoiler tag: Spoiler » (1) Because Keiko was injured in some weird shuttle accident, the O'Brien baby is surgically transferred to Kira, who must now carry him to term. This was done as a convenience since Nana Visitor (Kira) was actually pregnant for real. (2) Liquidator Brunt tricks Quark into reneging on a contract, so the Ferengi Commerce Authority revokes his business license and bars him from doing business with other Ferengi.
Odo contracts an unknown ailment; tensions rise between the Klingons and Federation.
🙄
Annoying Bashir Moment: Nearly skipping a stone into the Founders. "Oh... right..."
❕
Spoiler » As punishment for harming another changeling, the Founders transform Odo into a solid in this episode.
Thoughts: I rated this lower than the others. I just felt like it was "average" for a season finale. It wasn't bad, but I didn't think it was anything special, either.
Watch Recommendation: It's a season finale with important story developments, so it's a "Must Watch."
