• The episode title refers to the previously unseen Starbase 80, first mentioned in season one’s “Terminal Provocations”. It has the reputation of being a place where Starfleet consigns it’s worst officers.

    • In the season premiere, “Dos Cerritos”, we learned that the Cap’n Freeman of the alternate universe featured in that episode was stationed at Starbase 80.

• This season’s ongoing plot, Boimler’s facial hair, has progressed to the point where he’s got a little chin beard situation. Good for him.

• It’s Matt and Kimolu! From Star Trek! The Cetacean Ops whales have technically not been seen since “Trusted Sources” in season three, though we were introduced to Swhale Swahlens, the gestalt being who was a combination of Matt and Steve Stevens in “Twovix”.

• The pleasure planet Casperia Prime was first mentioned in “Change of Heart”.

• ”I’m hosting their first annual scatting battle.” We learned that Cap’n Freeman performs vocal jazz in “Moist Vessel”.

• ”Nooooooooooooooooo!” Mariner was reassigned to Starbase 80 in “Trusted Sources”, and it resulted in her temporarily resigning her commision.

• The shuttlecraft that flies at the screen appears to be a Type 15 shuttlepod.

• ”Check me out, I’m a total T’Pol over here.” The USS Cerritos crew needs to slather themselves with a gel, in a scene inspired by ENT’s somewhat maligned decon chamber scenes.

• The corridors of Starbase 80 are modeled after those of the USS Enterprise as we saw them in TOS, down to the ascending Jeffries tubes, intercom units on the walls, and multi coloured caples across the ceiling supports. Everything is just somewhat more distressed. The most noticeable departure is the access hatch doors are octagonal as opposed to rectangular.

    • The turbolifts are also modeled after what we see aboard the Enterprise, requiring handles to be turned to operate.

• We are introduced to commander Kasia Nox, who appears to be wearing a pre-Federation, ENT style uniform, including the gold piping for command. Though she has gold circular rank pips, and not the rectangular ones used by the crew of the NX-01.

    • In “Trusted Sources”, the Starbase 80 crew who arrived on the Cerritos to transport Mariner were wearing yellow jumpsuits. We also see green, and blue jumpsuits in this episode.

• Chief engineer Gene Jakobowski is played by Stephen Root, who also played Klingon captain K’Vada in “Unification I” and “Unification II”.

    • Like Nox, Gene wears an ENT style uniform. Later, in the arcade, Gene is also wearing a vest similar to the one Scotty first wore in “Star Trek: The Voyage Home”.

• ”Yeah, this base is basically controlled by a knife gang.” The Acamarians were introduced in “The Vengeance Factor”, and we learned about the Gatherers, a group of Acamarians who refused to accept the peace of nearly 300 years of blood feuds between clans, and became roving marauders.

    • One of the vendors in the food court area aboard SB80 has a sign advertising Parthas, a dish the Acamarian assassin Yuta prepared for commander Riker.

    • Another vendor’s sign reads ”Lornak’s.” the Lornak clan was wiped out by the blood feuds.

• Among the…second hand items at the vintage clothing store are:

    • TOS style female red operations uniforms

    • TOS style male blue sciences uniform shirts

    • Command gold ”new” uniform jackets of the sort worn by the Enterprise crew in DIS season two

    • SNW style female gold command uniform skants

    • TNG season one and two, blue science uniform top

    • A mirror universe dagger

    • A TMP security officer helmet

    • A TMP style admiral’s uniform

    • The jacket worn by Ruk in “What Are Little Girls Made Of?”

    • The fedoras worn by Kirk and Spock in “A Piece of the Action”

    • A TOS style Klingon uniform with baldric

    • One of the harnesses worn by the Edo, including testical bulge

    • A Nazi officer’s cap, presumably from “Patterns of Force”

    • A type-3 phaser rifle of the sort introduced in “Star Trek: First Contact”

    • A movie era command division maroon uniform jacket

    • A movie era expedition jacket, as introduced in “Star Trek: The Search for Spock”

    • A hat seen worn by Vulcan technicians in “Star Trek: The Voyage Home” and Tendi when she attempts to help O’Connor ascend in “Moist Vessle”

    • TOS era tricorders

    • One of the Starfleet cylindrical shoulder bags occasionally seen on TNG

    • A giant pile of TOS era red shirts

• Doctor Harrison Horseberry was affected by the Tarchannen parasite that affected a Starfleet Outpost on Tarchannen III, as well as the away team of the USS Victory sent to investigate, including Geordi, as recounted in “Identity Crisis”.

    • The victims of the Tarchannen parasites turn invisible to the human eye, but apparently being cured prevented the half of Doctor Horseberry that was genetically rewritten from displaying that trait.

• ”I’m El-Aurian, I think I know how to fight.” Though we did see Soren fight both Kirk and Picard in “Star Trek Generations”, it has never been established that fighting is something El-Aurians are well known for.

• ”We don’t have combadges, we use old wall comms.” The SB80 officers who came to pick up Mariner in “Trusted Sources” did have combadges.

• In the arcade we see:

    • A “Space Invaders” style game where the player controls a Valdore-class Romulan ship defending against descending Starfleet Constitution-class ships

    • A game called “Cardboard Chinos” which has a sign that appears to be a Caitian in a box, much like we saw Doctor T’Ana playing with a box in “We’ll Always Have Tom Paris”

    • A game featuring the Koala. Why is he smiling? What does he know?

    • A game called “Ferengi’s Fortune” that looks to play like “Joust”

    • A game called “The Captain’s Chair”; there is a real world video game titled “Star Trek: Captain’s Chair” though this does not appear similar

• Jet is riding a Toby the Targ children’s ride. Toby the Targ. B’Elanna had a Toby the Targ plush with her aboard the USS Voyager according to Tom Paris in “Tsunkatse”.

• Doctor Horseberry discovers there is an anaphasic consciousness named Clem controlling Matt. Doctor Crusher’s deceased grandmother’s body was controlled by the anaphasic being Ronin in “Sub Rosa” and he used her to attack Data and Geordi with tendrils of green energy.

• Doctor Horseberry is able to exorcise Clem by hitting Matt with a pool net. Violence also disrupted Ronin’s influence in “Sub Rosa” when Doctor Crusher attacked him with a phaser.

• The SB80 crew is able to provide Clem with a stable vessel for them to inhabit. In “Sub Rosa”, Ronin’s being was tethered to an ancient candle holder.

    • Clem’s vessel looks a lot like a microwave, which is kind of a modern candle when you think about it.
