who's coming home."
The first shot of the episode gives us an old man, injecting himself with a hypospray, just prior to a young woman (Rachel Robinson) knocking at his door. So, what was in the hypospray?... Oh: the young woman, Melanie, claims that the old man (Tony Todd) is Jake Sisko (Cirroc Lofton). ...What? Oh: Melanie claims that Jake is her favorite author, and always wondered why he stopped writing after Anslem and Collected Stories were published. She has tracked him down, and Jake decides that tonight, of all nights, is the time to tell the story of why he stopped telling stories: "My father died."
After the credits, we begin one of the episode's many Flashbacks: to the USS Defiant in the "present day" of DS9 (i.e., Lofton as Jake), with the elder Jake narrating. Though Jake was nose-deep in the writing of Anslem at the time, his father convinced him to come out to the Bajoran Wormhole to watch it undergo an "inversion," a natural wonder that only happens every 50 years or so.
Unfortunately, most natural wonders involve the Star Trek Shake, which rattles something loose in the Defiant's warp core. Disobeying orders, Jake follows Sisko down to Engineering, and father and son successfully get the core stabilized before it explodes. All is well, and Sisko hands back the bit of Applied Phlebotinum Jake gave him... as a bolt of energy slants out of the warp core and vaporizes him.
Old Jake: People do. Time passes, and they realize that the person they lost is really gone. And they heal.
Melanie: Is that what happened to you?
Old Jake: No. I suppose not.
Jake, now totally orphaned, rattles around DS9; everybody is nice to him, but that doesn't help a whole lot. Even worse, his father appears to him while he sleeps—not as a ghost or a nightmare, but seemingly whole and disoriented, before immediately disappearing again. The first time Jake thinks it was a dream, but the second he is able to rush Sisko down to Sickbay, where Dax and Bashir confirm that this is the real Sisko, somehow Unstuck in Time. Unfortunately they are not able to re-stick him before he disappears again. Even worse, between the loss of The Emissary and the increased Klingon aggression showcased in the previous episode, the Bajorans have lost faith in The Federation. Jake and all other Starfleet personnel are obliged to withdraw from the station. While on Earth, Jake (now played by Tony Todd in flashbacks as well as in "the present") settles down in Louisiana with his grandfather, marries a Bajoran painter, Korena, and appears ready to put everything behind him. ...Until Sisko drops in again, drawing Jake's attention away from his life and back to that of his father's.
Jake goes back to school for a degree in temporal mechanics, abandoning his writing career and his wife to do so, and deduces that his best opportunity to get his father back will be to take the old Defiant back to the wormhole as it undergoes another inversion. Aided by Captain Nog and the now-elderly Bashir and Dax, he sets up a device that will hopefully pull Sisko back into the timestream. Instead, it pulls him out of time for a short chat. Sisko begs Jake to move on and live his life, to put the tragedy behind him, but to no avail.
This brings us back to "the present," where the elderly Jake and the young Melanie sit in that house in Louisiana. Jake explains that he has finally worked out the nature of the connection between himself and his father: Jake acts like an anchor, continuing to drag his father forward through time. If Jake were to somehow sever that connection when his father is present, it should act as a giant Reset Button, sending his father back to the moment of the accident. But how is he going to mash the... Is that what was in the hypospray?? Is that why Jake chose today of all days to tell this story? Evidently so. He gives Melanie a copy of the work of fiction he was toiling over before she arrived, and some parting words of wisdom:
Jake settles himself in to wait, eventually drowsing; when he wakes up, Sisko is there. Sisko clearly plans to make the best of what little time he has with his son, but Jake has even less.
Old Jake: For you, and for the boy that I was. He needs you, more than you know. Don't you see? We're going to get a second... chance.
Courtesy of his son's warning, Sisko is this time prepared. He makes a Diving Save, shielding both him and Jake from the blast of energy. Jake is astonished: how did Sisko know that was going to happen? But Sisko is more preoccupied with his son, who gave up his life to save them both.
- A Day in the Limelight: For the first time in the series, Jake is front and center, though ironically, Cirroc Lofton is absent for much of the episode.
- Adult Fear: A father dies, and his beloved son never truly recovers from the loss - progressively throwing the rest of his life away in his inability to move on. Sisko gets small glimpses of his son's life over the decades as Jake loses sight of everything that made him happy, and is progressively more distraught with each encounter.
- Back to School: Adult Jake earns a degree in temporal mechanics, as part of his plan to save his father.
- Big "NO!": Ben, when he realizes that Jake has committed suicide for him.
- Jake gets one earlier when his father disappears, and again later when his first attempt to save Sisko fails.
- Break Out the Museum Piece: The Defiant gets de-mothballed in the future by Jake & friends, presumably in order to recreate the accident as closely as possible. Dax states that just about the only thing that still worked, when they started rehauling her, was the replicator!
- Determinator: Jake, hoo boy. He devotes his entire adult life to getting his dad back.
- Disappeared Dad: Stuck out of time, but still.
- Famous Last Words: "Don't you see? We're finally going to get a second.....chance....."
- Framing Device: An elderly Jake Sisko relates the reason he stopped writing to a young fan of his.
- Heroic Sacrifice: Jake's eventual solution.
- Holographic Terminal: Bashir on the un-mothballed Defiant comments on how long it's been since he's used a two-dimensional console, suggesting that Starfleet has switched to these.
- How We Got Here: Albeit with Jake Sisko as an old man.
- I Want Grandkids: Sisko says this when he visits Jake and Korena in New Orleans.
- It Was a Dark and Stormy Night: This actually is how the episode begins.
- Manly Tears: Jake practically spends half the episode with this! (As will the viewers, in all likelihood.)
- The Mourning After: A filial rather than romantic version, and justified given the nature of it. It's hard to find closure for a disappearance under ordinary circumstances, much less when your loved one keeps re-appearing. Ben, however, repeatedly insists that Jake needs to move on with his life.
- Parental Substitute: Dax steps in as a maternal figure for Jake after his father's apparent "death."
- Pet the Dog: Quark gives Nog some time off work so that he and Jake can use the holosuite.
- Putting the Band Back Together: Jake does this with the Defiant's crew during the rescue mission.
- Rank Up: Nog does this a few times, eventually becoming The Captain.
- Reset Button Suicide Mission: Benjamin Sisko is trapped in subspace by a Negative Space Wedgie and periodically comes back for a few minutes at a time into the life of his son Jake, at ever increasing intervals. Jake abandons his writing career and spends his whole life trying to find a way to save his father. Eventually he determines that the tie between them can only be severed at the point of Jake's death. He poisons himself so that he'll die at the exact time of Benjamin's next visit, sever the tie, undo about sixty years, and put Benjamin back a few seconds before the anomaly, giving him time to jump out of the way.
- Set Right What Once Went Wrong: Jake spends his whole life trying to do this. It's only when his life ends that it happens for real.
- Shout-Out: A close look at the manuscript Jake is editing in the first flashback reveals it to be "Commodore Hornblower". It's quite appropriate, as Star Trek took in a lot of inspiration from the Hornblower books.
- Writer Michael Taylor said the episode was inspired by reclusive writer J. D. Salinger doing an interview with a high school student in 1980 who just showed up at his door.
- The Slow Path: A rare example of seeing this trope from the perspective of the one on said path.
- This Is My Story/Whole Episode Flashback: The general Framing Device of the episode, as an elderly Jake tells Melanie about his tragic tale.
- Token Minority Couple: A rather strange example. The wife of Jake (who is African-American) is a Bajoran - who is played by a black actress.
