• Ensign Gamble records the stardate as 2184.4 in his junior medical officer’s log. Which, of course, would predate the previous log entries this season, if stardates progressed through increasingly larger numbers, as they do in every series in this franchise other than TOS, and TAS.

Episode	Stardate
“Hegemony, Part II”	None given
“Wedding Bell Blues”	2251.7
“Shuttle to Kenfori”	2449.1
“A Space Adventure Hour”	None given

    • Gamble says he has been stationed on the USS Enterprise for six months. In “Wedding Bell Blues”, when Gamble is introduced, it was established that he was a temporary replacement for nurse Chapel, and that she had been off the ship for three months, indicating that at least three months has passed between that episode and this one.

• Gamble comments that Korby is working on ”corporeal transference.” In “What Are Little Girls Made Of?” Korby will have transferred his own consciousness and that of his associate, Brown, into android bodies.

• ”She is an excellent dance instructor.” La’An was teaching Spock how to dance in preparation for his reunion with Chapel in “Wedding Bell Blues”, but it seems as though as of the end of “A Space Adventure Hour”, the lessons have progressed from tango to horizontal mambo.

• The Vadia IX magnetic anomaly is located at the Lafarge Quarry. On the other side of the ridge you’ll find:

    • The camp of rebels against the Terran Empire - “The Wolf Inside”

    • Talosians - “Light and Shadows”, “If Memory Serves”

    • Some Trill itronok - “Jinaal”

• Berto Ortegas is aboard the Enterprise as a documentarian. The LDS episode, “Trusted Sources”, featured an FNN reporter documenting the missions of the USS Cerritos.

• Chapel and Korby speculate that the M’Kroon are descendants of an ancient civilization that achieved immortality. Star Trek is lousy with powerful ancient civilizations that, for whatever reason, are no longer present to exert their direct influence on the galaxy, including:

    • The T’Kon Empire - “The Last Outpost”

    • The Iconian Empire - “Contagion”

    • The Progenitors - “The Chase”, DIS season 5

    • The D’Arsay - “Masks”, “Room for Growth”

• Doctor M’Benga declares that his scans find Gamble to be brain dead. Other people who’ve been brain dead include Chakotay in “Cathexis” and Rick Berman for most of his career.

• ”This thing…is older than anything I’ve ever seen.” Pelia is of a long lived species, Lanthanites, and has been alive since at least the 6th century BCE.

• Spock uses a set of alien goggles to view the well of Vezda orbs. One of the orbs floats up, and a toothy monster inside the sparkling light snarls at him, not unlike the crew of the USS Yosemite who’d been transformed into transporter snakes and assaulted Barclay in “Realm of Fear”.

• Gamble has been possessed by one of the Vezda entities. Other characters who’ve been possessed by malevolent entities include:

    • In “Wolf In the Fold” Scotty was briefly possessed by Jack the Ripper

    • In “Clues” Troi was possessed by a Paxan

    • In “Power Play”, Data, Troi, and O’Brien were possessed by non-corporeal prisoners

    • In “Masks” Data was possessed by several figures from D’Arsay myth

    • In “Cathexis” Tuvok was possessed by a Komar

    • In “The Reckoning” Jake Sisko was possessed by the Kosst Amojan Pah-wraith.

• Vezda Gambel references Rukiya Doctor M’Benga’s terminally ill daughter whom he kept in a transporter buffer for the first half of season one, let go of so she could join with a sentient nebula in “The Elysian Kingdom”, and promptly forgot about until now.

• Captain Batel, who is presumably now a Gorn hybrid after her treatment following “Shuttle to Kenfori”, recognizes the entity in Gamble, and the pair fight in sickbay. It is unclear where Batel got the large boulder she throws at Vezda Gamble like the Gorn in “Arena”, but we did learn in “Strange Energies” that Starfleet does have medical boulders.

• La’An voices suspicion that the ancient site might be a prison to house the Vezdas. In “Power Play” the entities that possessed Data, Ro, and O’Brien were prisoners whose consciousness was separated from their bodies and trapped in a magnetic storm.

• ”Curiouser and curiouser” Spock quotes “Alice’s Adventures in Wonderland”, a book Amanda Greyson would read to him and Michael Burnham when they were children, as per “Once Upon a Planet” and “Context is for Kings”.

• Scotty traps the Vezda after it escapes Gamble’s corpse, and stores it in the transporter buffer. In “Wolf In the Fold” Spock scattered the Jack the Ripper entity across deep space with the transporter.
