Apocalypse Rising |
|
|
|
| |
Sisko, O'Brien, Odo, and Worf go undercover on the Klingon homeworld to expose a Changeling impersonating Gowron.
|
|
|
|
|
| 🤰 |
Regarding her pregnancy, Kira's says to Bashir, “But don't forget, this is still your fault.” She is referring to the fact that Bashir performed the transfer of the O'Brien baby to Kira's womb. This line is actually a bit of a fourth wall-bending joke, because actor Alexander Siddig (Bashir) is the real-life father of Nana Visitor's (Kira) baby. |
| |
|
|
Nitpickery: All Sisko had to do was push the button. I guess he really wanted that medal. |
| |
|
|
Watch Recommendation: This episode provides a conclusion to the previous one, but it's only rated as “Recommended” since it doesn't really contain much vital information essential to the series. |

The Ship |
|
|
|
| |
Sisko fights to keep a crashed Jem'Hadar ship that he's salvaged.
|
|
|
|
|
| |
|
|
Nitpickery: I'm no military strategist, but couldn't Sisko have at least tried to negotiate with Kilana for a med kit or something to help Muniz? |
| |
|
|
Watch Recommendation: It's a bit harrowing watching Muniz' condition deteriorate. No recommendation. |

|
|
|

Bashir and Jake lend a hand to a Federation colony under attack by the Klingons; Jake experiences shell shock.

Annoying Bashir Moment: Smug babbling during the teaser. I liked the part where Jake's inner monologue drowns him out. |

The Assignment |
|
|
|
| |
A Pah-Wraith takes over Keiko's body and forces O'Brien to do her bidding... but not in a sexy way.
|
|
|
|
|
| |
|
|
Nitpickery: Did you notice, towards the beginning of the episode, Miles asks the Pah Wraith why it took over Keiko and not him, since he's the one who can perform all the work, but the Pah Wraith never answers the question because Julian conveniently interrupts the conversation by ringing the door chime? I love it when the writers get lazy. |
| |
|
|
Watch Recommendation: It's okay, and it's another episode that is pretty inconsequential for the rest of the series, so there's no recommendation here. |

Vice-Admiral Pips: Pips are awarded to episodes that are the most stand-out, representative examples of the series as a whole. This episode is a special tribute and a bit of a masterpiece. The only reason it didn't get full-Admiral pips is because it's not truly representative of the rest of the series. It is a one-off. A glorious one-off, but still a one-off. |

Watch Recommendation: You might want to watch the Original Series episode TOS 2x15: The Trouble with Tribbles before watching this one, but you certainly don't have to do that in order to understand or appreciate this episode. This episode is truly something special, and really is a “Must Watch.” |

Let He Who Is Without Sin... |
|
|
|
| |
Everyone acts like a bunch of jackwagons on Risa.
|
|
|
|
|
| ❌ |
Absurd actions with no consequences: Worf faced no consequences for what was at least “conduct unbecoming a Starfleet officer” but was probably actually an outright crime. |

Worf's RAP Sheet: Sabotage |
| 🔗 |
|
| |
|
| |
Thoughts: Do not think that I am taking sides in the Dax/Worf conflict, because both of them act like children in this episode. The fundamentalists' arguments are specious, at best, and Spoiler » WORF LITERALLY COMMITS SABOTAGE AGAINST AN ENTIRE FEDERATION PLANET. HE RUINED THE VACATIONS OF HUNDREDS OF THOUSANDS OF PEOPLE BECAUSE HE WAS IN A BAD MOOD. And that stupid story from his childhood that came out of NO WHERE does not even come close to explaining his actions. Argh. |

|
|

|
Watch Recommendation: This story has elements of how Deep Space Nine used to be while the Cardassians occupied it, and delves a little into Odo's history, but it's still not really important to the overall story. No recommendation. |

Star Trek: First Contact released
The film Star Trek: First Contact was released on November 22, 1996. However, the events of the movie don't actually take place until after the episode DS9 5x22: Children of Time. It's certainly not necessary, but you may want to wait until then to watch the film if you want to see events in chronological order.

The Ascent |
|
|
|
| |
Marooned, Quark and Odo must climb a mountain to survive.
B-plot: Jake and Nog become roommates and have some trouble getting along.
|
|
|
|
|
| 🔗 |
|
| |
|
| |
Nitpickery: In the B-plot, the writers make the new roommates, Jake and Nog, sort of like The Odd Couple. One is fastidious while the other is a sloppy “free spirit,” and obviously this conflict is a formula for HILARITY! The stupid part that I can't get over is that Jake's messiness apparently comes in the form of him regularly taking out every article of clothing that he owns and tossing them anywhere there's an open spot. Either that or he changes clothes every hour or so. There's a shirt in the replicator... this isn't just being untidy, this is some kind of psychopathy! |
| |
|
| |
Thoughts: I get exhausted just watching this episode. The contrasting tropes of “two characters at odds must work together to survive against insurmountable challenges” and “two characters who were friends are now at odds” is a little tired, so I had to knock off a half-star from my rating of an otherwise average episode. |
| |
|
|
Watch Recommendation: Neither of these stories matter in the long run. No recommendation. |

Someone is murdering Kira's old Resistance comrades.

|
|
| ❌ |
Absurd actions with no consequences: Kira goes off half-cocked, risking her own life and the life of the O'Brien baby, and it's never addressed. She also strikes not one but THREE fellow officers, nearly vents an entire section of the station into space, uses the transporter to secretly move around the station, steals security files and a runabout... but we'll never speak of this incident again. |
| ❕ |

In this episode, Dr. Bashir is actually a changeling impostor who repairs Kira's placental perforation. Yikes!
|
| |
|
| |
Thoughts: This story has some real unrealized potential, if only they had run with it instead of wrapping it all up in one episode and never mentioning it again. Kira's emotions are obviously running high, but she also has a baby to think about. I would have liked to see some confrontation between the O'Briens and Kira over this, as well as some more fallout from Kira's loss, but the events of this episode are literally never mentioned again. |
| |
|
|
Watch Recommendation: While the episode does build some character for Kira and goes into some of her history as a member of the Bajoran underground, it's not a good episode, and it's frustrating to watch Kira make so many poor choices. No recommendation. |

Spoiler » This contains spoiler information for 5x14: In Purgatory's Shadow. Come back after you've watched it. Continue anyway » Dr. Bashir doesn't appear in this episode, but he is still a changeling impostor at this point. (Yikes!) |
| 🔗 |
This is part 2 of 3 in the Sisko vs. Eddington story arc. The first episode is DS9 4x22: For the Cause and the last one is DS9 5x23: Blaze of Glory. |
| |
|
| |
Nitpickery: We've never seen Sisko do any boxing before. We'll never see Sisko do any boxing again. But we need a way to show that he's frustrated and apparently we couldn't think of anything but the old punching-bag trope! |
|
Watch Recommendation: Because it's an important part of the Eddington arc, this episode is a “Must Match.” |

During a briefing in the wardroom, Sisko mentions “the recent Borg attack.” He is referring to the events from the film Star Trek: First Contact, which premiered less than three months prior to this episode. Sisko also speaks of “Professor Kahn of the Trill Science Ministry,” who is a new host for a former wife of a former host of Dax's... uh, yeah. Anyway, we met Dr. Kahn back in DS9 4x06: Rejoined. |

Spoiler » The Dominion fleet, along with Dukat's ship, leaving the station and heading to Cardassia is likely the meaning behind the vision of locusts that Sisko saw in DS9 5x10: Rapture. |
| |
|
| |
Thoughts: It occurred to me during this episode that whenever a Starfleet officer is taken prisoner by anyone, their combadges are always confiscated, but they always seem to keep their rank pips. Starfleet should probably hide some tech in those pips that can be used to aid in escape! |
| |
|

Doctor Bashir, I Presume |

Crossover: Lewis Zimmerman and the Mark 1 EMH (VOY) |
| 🙄 |
Annoying Bashir Moment: I mean... honestly, mostly the entire episode. |
| |
|
| |
Thoughts: It has been four and a half seasons, and it seems the writers just don't know what to do with Dr. Bashir (other than having him get captured and replaced by a changeling, twice). And then someone came up with this episode. Spoiler » The big reveal is that Dr. Bashir's parents had him genetically altered as a child because he wasn't keeping up with other kids his age. They had his physical and mental abilities enhanced to turn him into the successful doctor he is today. Since genetic alteration is illegal in the Federation (see: Khan Noonien Singh), Bashir's career was suddenly at risk when his secret was discovered. A deal was struck where Julian's father would go to prison for two years so Julian could stay in Starfleet (and we'll never see or hear from his parents again after this episode). Now, what purpose did this plot twist serve except to make Bashir even more aloof and annoying? Someone who is naturally brilliant and smug about it is annoying enough, but now we know that Bashir's intelligence was unnaturally engineered, making all those times he was singing his own praises even more infuriating! And that is why I rated this episode lower than others have rated it. |
| |
|
|
Watch Recommendation: I'm trying not to have too many episodes rated “Must Match” so this one is only “Recommended.” It's not one of my favorites, but there is an important REVEAL that you should probably know about. So give it a watch if you want to see some fun Robert Picardo crossover action, or you can just keep up-to-date by revealing the spoiler above. |

|
|
|

|
| 😱 |
Scary episode (Of that genre, anyway. Actual fright not guaranteed.) |
| |
|
| |
Nitpickery: It bothers me that the away team categorizes items they need into three groups: “must haves,” “could use,” and “would be nice,” but O'Brien splits the group into three teams and assigns one of those lists to each of the groups, essentially devoting equal resources to each list instead of prioritizing them appropriately. |

|
| |
|
| |
Thoughts: I like this episode. It's meant to be a silly episode, and I think it does a good job of mixing a silly A-plot with a serious B-plot. Trek often has trouble properly balancing humor and drama, so this is a refreshing success. It's cute how all of Jake and Nog's side-quests brings a renewed sense of happiness to the station. Well, except for poor Leeta. |
| |
|
|
Watch Recommendation: While this episode is considered to be the beginning of an 8-episode arc, it really is mostly focused on this silly one-off story about the baseball card, so I think you can safely skip it without having to fear the soulless minions of orthodoxy. The next episode is much more important. |

If Sisko hadn't prevented Bajor from joining the Federation in DS9 5x10: Rapture, Bajor would not have been able to independently sign a non-aggression pact with the Dominion in this episode. |
| |
|
| |
Thoughts: It's important to not think too hard about that magic infinite minefield made with magic infinite mines that blow up ships and also magically create more mines so there's always more magic infinite mines to blow up more ships. Also, they're cloaked for some reason. |
| |
|
|
Watch Recommendation: It's a very important season finale and a “Must Watch.” It's also the sixth episode on the “Bare Minimum” list. |
