• ”I swear, you’ve read those first contact protocols more than Picard.” Gwyn is too polite to reply that she, an alien child who grew up in a Delta Quadrant labour camp, has has no context for who Admiral Jean-Luc Picard is, even if he was captain of Starfleet’s flagship.
• Asencia [Jameela Jamil] escaped capture in the previous season’s “Supernova, Part 1” after murdering the Diviner.
• Janeway’s admiral’s log records the stardate as 61859.6.
• The most recent stardate prior this episode was 61302.7, given in the fourteenth episode of season one, “Crossroads”.
• This is the first time we’re learning that the Diviner’s [John Noble] name was…is? Ilthuran. In season one, he was only ever referred to by his title.
• ”We were just a bunch of nobodies on a rock. No hope, no future, until we found that ship.” Dal is referring to the events of the season one premiere episodes “Lost and Found”.
• The crew of the USS Voyager and their allies used temporal shielding during conflicts with the Krenim during “Year of Hell” and “Year of Hell, Part II”.
• ”Refuse to help my own daughter? Surely I don’t make that bad of a father, do I?” The Diviner choose to abandon Gwyn on a sentient planet that manifested the nightmares of its inhabitants and then consumed them in “Terror Firma”.
• The Vulcan Nova Squadron cadet is named Maj’el, for the late Majel Barrett, who portrayed:
• Number One
• Christine Chapel
• Lwaxana Troi
• The Computer in TOS, TAS, TNG, DS9, VOY, ENT, “Star Trek Generations”, “Star Trek First Contact”, “Star Trek Insurrection”, “Star Trek Nemesis”, and 2009’s “Star Trek”
• Several other characters in TAS, including Amanda Greyson and M’Ress
• This is the first on screen mention of a sonic toilet.
• Maj’el claims that Vulcan psychic abilities are enhanced in the presence of other telepaths. I believe this is the first time this has been explicitly stated, or even implied on screen.
• One of the crew who gets on the turbolift with Maj’el calls for deck 32. In the previous episode, Zero said that the USS Voyager A has 29 decks.
• ”Warp cores are so beautiful up close. It’s the delta radiation.” Delta radiation? You mean the thing that melted captain Christopher Pike and consigned him to a tortured existence in a beep chair? Too soon, Zero, too soon.
• Mirror Charles Tucker III was also deformed by long term exposure to delta rays.
My assumption was error in the "Star Trek: First Contact" tradition.
