Sisko, Jake, Ezri and Grandpa Sisko head off to find the Orb of the Emissary. While Worf is joined by Quark, Julian and O'Brien in taking out a Dominion shipyard and getting Jadzia into Sto-Vo-Kor.
- Big "SHUT UP!": When Quark is trying to get a little gratitude from Worf in the form of him saying "two words" (which, of course, are "Thank you"):Worf: BE QUIET!
Quark: That's two words, all right. Just not the two I was hoping for.
- Blue and Orange Morality: Showcased with the Prophets, who took over the body of an unwilling woman, forcing her to marry Joseph and ensure Sisko's birth.
- Continuity Nod: Sisko has another vision as Benny Russell. Only this one is a Pah-Wraith attempt to keep him away from the Orb. Damar appears as his psychiatrist.
- May be some Fridge Brilliance here, to explain the entire Benny Russell vision. The whole thing was a Pah-Wraith Mind Rape attempt to leave Sisko trapped in that world, accepting the institutionalized prejudice and persevering in a Sisyphean effort to get published.
- The use of Damar is interesting also, as he was not given an Expy in the earlier Benny Russell episode.
- Also Quark again refers to himself as "Quark, son of Keldar" while dealing with Klingons.
- Crusading Widower: How does Worf deal with Jadzia's death? By blowing up a Dominion shipyard.
- Divine Intervention: Sisko learns his birth was due to the possession of his mother by a Prophet.
- Double Standard: Rape, Divine on Mortal: The Prophets apparently weren't too picky about consent when they mind-controlled Sisko's mom into marrying his dad, considering that she bolted the second her agency was returned to her.
- Due to the Dead: Everyone's surprised that even Quark is joining the mission in Jadzia's memory.
- The Final Temptation: The Pah-Wraiths try to keep Sisko from opening the Orb of the Emissary by giving him a vision placing him in the shoes of Benny Russell, who was placed in a psychiatric hospital after his mental breakdown and continued writing his "Deep Space 9" stories on the walls of his cell. Appearing as an orderly, the Pah-Wraiths try to convince Sisko to abandon his efforts in the real world by letting him paint over his scrawling with the promise that it was for his own good. Sisko is tempted for a moment, but comes around with Ezri's help.
- Got Volunteered: Ezri never trained to join with a symbiote. But since she was the only Trill aboard, she needed to join with it immediately, getting a quick explanation from the USS Destiny's chief medical officer before surgery.
- I Am X, Son of Y: When Quark shows up for the mission, he declares himself "Quark, son of Keldar" (a Continuity Nod to "The House of Quark").
- Kill It with Fire: No bigger fire than a frigging sun to take out the Dominion shipyard.
- Motor Mouth: Ezri goes a mile-a-minute due to being new to the whole Joined thing.
- Noodle Incident: Whatever happened in the Klingon mess hall, apparently involving gagh.
- Not So Different: Clearly, neither the Prophets nor the Pah'wraiths are above violating people's minds and free will...
- O.O.C. Is Serious Business: Worf apologizes for being a jerk. No one else can believe their ears.
- Palm Bloodletting: Once again, part of a Klingon ritual. Quark isn't too thrilled about it.
- Past-Life Memories: A recurring issue for Ezri—Torias's death makes her nervous about flying in a shuttle, and she reflexively orders raktajino (which she ends up hating) from the replicator because it was Curzon and Jadzia's favorite drink.
- Room Full of Crazy: The walls of Benny Russell's room in the psych ward in Sisko's vision are covered with what we are led to believe is a novelization of every episode up to that point.
- Solar Flare Disaster: Worf and co create one to wipe out a Dominion shipyard.
- Stuff Blowing Up: Doesn't get much bigger than a solar plasma ejection.
- Vomit Discretion Shot: We cut to the runabout just after they've finished cleaning up the results of Ezri's motion sickness.
- What the Hell, Hero?: Martok calls Worf out for being a jerk to his friends. Leads to the aforementioned apology.
