Samantha Delaney and her Dark Starship head for Earth to unleash the temporal weapon, blasting through Starfleet starships en route. The USS Cantabrian is hot on her trail, and the final showdown in Earth's orbit comes at a great cost...
- Anne Lansing makes her first guest appearance in person in Star Trek: The Cantabrian Expeditions in this episode.
- The Cantabrian is one of the starships sacrificed in order to stop the Dark Starship.
- Three days before his birthday – indicating part of this episode takes place around 25 November 2373 – Noah Wrightson sacrifices himself in order to stop the temporal weapon, being sent somewhere unknown in time-space.
- The episode ends with some threads for Season 3, including a distraught Daniel Radke turning after Wrightson's disappearance and punching Delaney so hard he fractures her skull in three places, leading to a court martial for assault of a civilian between Seasons 2 and 3. Another thread continuing in Season 3 is most Cantabrian crew are on Earth awaiting the USS Cantabrian-A's launch at season's start.
