• This is the series finale of the “Star Trek: Discovery”, the first instalment of what we might consider to be the modern era of Trek.

    • Premiering in 2017, DIS ran for five seasons over the course of seven years.

    • The show has a total of 65 episodes.

• The episode title, “Life, Itself” is a reference to the 1973 Disney animated classic, “Robin Hood” wherein the titular outlaw says the line, ”Marian, my darling, I love you more than life itself.” Q transformed captain Picard into a version of the cartoon fox in "Qpid".

• This episode’s credited director is series executive producer, Olatunde Osunsanmi, who has directed thirteen prior episodes of DIS, and two “Short Treks”. HIs presence is immediately apparent in the cold open when the first thing we see is the camera rotating upside down. The use of the flame jet emitters in the bridge is also one of his hallmarks.

    • Jonathan Frakes is the uncredited director of the final sequence of the episode, which was done in reshoots after it was announced the series was ending. That means Frakes is now responsible for closing out two Trek series, both DIS and ENT.

• I previously speculated that the floating wickets at the end of this season’s credit sequence were from the bridge of the Breen dreadnought, but that was incorrect. The interior of the Pregenitor technology features floating wickets as windows into different biomes, and they resemble the ones in the credits much more closely.

• We see a dead Breen whose helmet is smashed open and a bunch of green goo is spilled out, perhaps confirming the fan speculation that when a Breen dies while not in its solid form, their body loses cohesion, and that is why Worf’s statement in “‘Til Death Do Us Part” that no one had ever seen a Breen outside of the refrigeration suit remained true, despite Kira and Dukat incapacitating two Breen to steal their suits for disguises in “Indiscretion”.

• The Breen that tackles Burnham is the one who had a tether attached to their suit before attempting to enter the Pregenitor technology in “Lagrange Point”; you can see the snapped tether still protruding from their back.

• Production error: The hurricane force winds are strong enough that Burnham and the Breen whom she’s fighting are both blown horizontal, but Burnham’s braids remain hanging down from her shoulders.

• The final credits sequence brings back graphics from earlier seasons:

    • The captain’s chair from season one

    • The environmental suit from season one

    • The paired Klingon mek’leths from season one

    • The graphical representation of Zora from season four

    • Book’s unnamed ship, from season three

    • The flip communicator from season one

    • The Red Angel suit from season two

    • The DMA from season four

    • The badge from season one

• The Breen fighters we see have an asymmetrical design with some elements of what we saw from the Breen interceptors in DS9.

• ”This is like the avalanche all over again.” Rayner recalls the events of “Red Directive”.

• ”Ever since Jinaal, I’ve been trying to figure out what it means. This change inside me, or whatever it is.” Doctor Culber refers to the third episode of this season by its title.

• ”I know what it’s like to lose somebody who means everything to you. I do. But thankfully, I got him back.” In “Will You Take My Hand?”, Ash Tyler left to support L’Rell’s bid to become chancellor. They were reunited in “Saints of Imperfection”.

    • Moll does not get L’ak back.

• In the interior of Saru’s shuttle, we can see a pathway drive for the first time, though it was mentioned in the season four premiere, “Kobayashi Maru”.

• Burnham and Moll locate a cairn. Burnham surmises it is the grave for the sixth scientist, the one whom Jinaal mentioned having died when the group located the Pregentior technology.

• ”Nine. That’s the number you need to make a larger triangle.” There are ten triangles on the Pregentior interface when we’re shown an unobstructed close-up. Moll is as good at counting as L’ak was at not stabbing himself.

• The USS Discovery A destroys the fleet of Breen fighters pursuing them by using a photon torpedo to ignite a pocket of plasma. In “Shadows and Symbols”, the IKS Rotarran used an EM pulse to trigger a solar plasma ejection, destroying a Dominion shipyard.

• Doctor Culber remembers the resonance frequency of the Pregenitor technology portal from his time as host to Jinaal’s consciousness in “Jinaal”.

• ”My species are predators, and I have studied you like prey.” In season one of DIS, the Kelpiens were mentioned repeatedly to be a prey species, and Saru was the lens through which that was presented. It was not until “The Sound of Thunder” in season two that Kelpiens were established to have nearly driven the Ba’ul to extinction thanks to the changes they undergo post-vahar’ai.

    • In “Die Trying”, the medical hologram Eli claimed that Saru might be the last Kelpien to display biochemical traces of vahar’ai.

• The Progenitor whom Burnham meets reveals that her people were not actually the originators of the technology, and shares a theory that there was some sort of pre-Progentiors who created it, and them as well. Some sort of Pregenitors, if will.

• Apparently the Discovery A can perform a saucer separation. It’s unclear if this was a feature of the Discovery pre-refit, but in “The Apple” Kirk suggested, ”Discard the warp nacelles if you have to,” to Scotty in order for the USS Enterprise to be able to devote as much power as possible to the impulse engines.

• The Progenitor causes Burnham to experience four billion years of development in a moment. In “Hard Time”, O’Brien was implanted with memories of 20 years in prison, and it messed him up pretty badly for the rest of the episode.

• “Nothing here can bring him back. I’m so sorry.” Burnham informs Moll that the Pregenitor technology can’t be used to bring L’ak back to life. Things that have been used to bring characters back to life in Trek include:

    • Scotty was revived by Nomad after Nomad had killed him in “The Changeling”.

    • Spock died in “Star Trek: The Wrath of Khan” but the Genesis planet, revived his body as an infant, allowing for his katra, which had been transferred to Doctor McCoy, be returned to his now alive body.

    • Worf and Wesley were both killed in a battle with bestial soldiers conjured by Q. Riker resurrects them with his temporary Q powers.

    • Harry Kim had to die in “Emanations” to get transported back to the USS Voyager. The Doctor was able to revive him with medicine.

    • Neelix dies in “Mortal Coil”, but is revived with Borg nanoprobes.

    • Kelvin universe Kirk died in “Star Trek Into Darkness”, but Doctor McCoy was able to filter Khan’s augment blood through a tribble and save him. Or something.

    • Doctor Culber’s neck was snapped by Ash Tyler in “The Saints of Imperfection”, and beings that live in the mycelial network revived him using fungus material from an interdimensional transporter as his new body in “Despite Yourself”.

    • Shaxs died aboard an exploding Pakled clumpship in “No Small Parts”, but returned in “We’ll Always Have Tom Paris” with story of having visited the black mountain and fighting three faceless apparitions of his father.

• ”I realized we already have infinite diversity in infinite combinations.” The IDIC is a Vulcan philosophy first mentioned in “Is There In Truth No Beauty?” so that Gene Roddenberry could sell merch.

• Outside Federation HQ there is:

    • An Eisenberg-class starship

    • A Mars-class starship

    • A Saturn-class starship

    • A Merian-class starship

    • A Courage-class starship

• Among the trinkets in Kovich’s display are:

    • A Terran knife

    • A type-2 phaser of the sort introduced in season five of TNG

    • A bottle of Chateau Picard dated 2249

    • A VISOR, presumably the one Geordi wore beginning in season two of TNG

    • A baseball; it’s too clean to be Sisko’s so perhaps it’s Rom’s from “Parth Ferengi’s Heart Place”

    • Perhaps it’s noteworthy that Kovich does not have any items from the NX-01

• Kovich reveals himself to be Daniels, the temporal agent introduced in “Cold Front”.

    • Kovich says he’s from the USS Enterprise, but the NX-01 did not have the USS designation.

• Book had a confrontation with Talaxian pirates. Neelix established in “Non Sequitur” that Talaxian piracy is mostly cased around the procurement of haircare supplies.

• Molly was the endangered trance worm Book rescued from the Emerald Chain in “That Hope is You, Part 1”.

• In Burnham and Book’s 33rd century home on Sanctuary Four, they have the Tuli wood box in which the Eternal Archive and Gallery’s World Root cuttings were stored in “Labyrinths”, and captain Georgiou’s telescope, first seen in “The Vulcan Hello” and received by Burnham in “The Butcher’s Knife Cares Not for the Lamb’s Cry”.

• We learn that Burnham has attained the rank of Admiral.

• There is a deer-like creature on Sanctuary Four that Burnham calls Alice. Presumably she named the creature for “Alice’s Adventures in Wonderland”, a book we learned Amanda Grayson read to her as well as Spock in “Context is for Kings” and “Once Upon a Planet”.

• ”I thought you’d be on your way to Crepuscula by now.” The Crepusculans were a pre-warp civilization in “The Vulcan Hello”. Georgiou and Burnham visited their world to help mitigate the effects of a drought caused by an industrial accident in nearby space.

• ”One, aye,” calls back to “People of Earth” where Book disguised himself as a Starfleet officer.

• The shuttle captain Leto picks Burnham up in is UFP-47.

• Book has planted the World Root cuttings on Sanctuary Four, and we see several trance worms swimming in a river.

• Starfleet HQ now has three of the station/ships in the 33rd century.

• We see DOTs working on restoring the USS Discovery to it’s original configuration before the 32nd century refit.

• ”I did hear a word in passing. ‘Craft.’” Zora encounters Craft in “Calypso”, according to her, almost 1,000 years after being left in a nebula.

• Despite the years that have passed, all the ships we see in attendance for the *Discovery’*s last mission are spaceframes we’re familiar with from the 32nd century.

• This episode was directed by Johnathan Frakes, who starred in the ENT episode, “These Are the Voyages...”

• Captain Burnham informs Rayner that the Breen Primarch Tahal is going to be arriving at their location in the next episode. We learned in “Erigah” that Tahal occupied Rayner’s homeworld, Kelerun, and used it as a staging point.

• The tool Book is using to help effect repairs on the spore drive looks to be the same one he used as a weapon against Burnham in their fight when the characters first met in “That Hope Is You, Part 1”.

• The Progenitor’s technology is contained within a structure carefully balanced at the point where the gravity wells of two black holes intersect, i.e. the Lagrange point. Hey, that’s the title of the episode! Which makes sense, because the rest of the episode must surely be about figuring out how to retrieve the structure from such a precarious position without being crushed, torn apart, or spaghettified by the intense gravimetric interactions. It would be silly if, say, the Breen dreadnought was to show up and simply yoink away the structure with a tractor beam while we’re still in the cold open, and the Lagrange point did not matter for the rest of the episode.

    • The structure containing the Progenitor technology looks like a large barrel. Somewhere in Sto’vo’kor, a warrior punches a wall and doesn’t understand why.

• Moll stores L’ak’s body in a portable transport buffer. Trek has been using the transport buffer to store people since Scotty did so in “Relics”, though the other engineer aboard the USS Jenolan, Franklin, a good lad, pattern degraded too far for him to also be retrieved. Presumably no one would notice if L’ak’s pattern degraded over time.

• Adira mentions having been part of the Earth Defense Force, which is what they were doing when introduced in “People of Earth”.

• Burnham’s plan for infiltrating the Breen dreadnought is to transport through a gap in the shield coverage near an exhaust port. In “Preemptive Strike”, Ro and a team of Maquis exploited a weak point in the USS Enterprise D’s shields created by the ship’s impulse engines to steal medical supplies.

• Rayner asks Tilly to be his acting first officer while Burnham and Rhys are on the Breen ship. Saru also promoted Tilly to be his acting first officer while she was still an ensign.

• The away team plans to move around the Breen dreadnought in replicated Breen suits. In “Indiscretion”, Kira and Dukat disguised themselves in stolen Breen suits to infiltrate a work camp.

    • When Burnham activates her helmet, it forms around her head, but her braids are still visible hanging down her back before the transport. Upon arriving on the Breen ship, Burnham’s braids are no longer exposed. Later, when Burnham deactivates the helmet, her braids are already hanging down her back before it starts to dematerialize.

    • Despite being Federation technology, the fake Breen suits still have Breen script in their HUD.

• Burnham uses the term “achworm” during her bluff, something Primark Ruhn called called the Federation representatives in “Erigah” before it became apparent that T’Rina speaks the language.

• Assembled at Federation Headquarters we see:

    • Two Eisenberg-class starships

    • A Saturn-class starship

    • A Merian-class starship

    • Two Mars-class starships

    • One starship of the same class as the USS Dresselhaus

    • One 32nd century Constitution-class starship

    • One 32nd century Intrepid-class starship

• T’Rina suggests sending the USS Mitchell to intercept Tahal’s fleet. The Mitchell first appeared in “Rubicon”.

    • ”A shuttle wouldn’t be remotely capable of engaging her entire fleet.” President Rillak seems to imply that the Mitchell could conceivably be a match for a Breen fleet, which I would argue is very appropriate for a ship named for Kenneth Mitchell, who played Kol, Kol-Sha, Tenavik, and Aurellio on DIS, and voiced the Tweerk captain, one of Ransom’s Starfleet black ops buddies, and a Romulan guard on LDS before his passing.

• Burnham uses her xenoanthropology specialization to understand that joining a Breen feast day would be considered a good thing to do. Xenoanthropology was established as Burnham’s scientific focus in the series premiere, “The Vulcan Hello”.

• Burnham relates the results of her self introspection in “Labyrinths” to Book.

• ”Grum of osikod,” is a reference to the Kellerun epic, The Ballad of Krul. Burnham quoted the passage in which it’s mentioned to Rayner in “Mirrors”.

• ”Oh, holy schnoodle.” In “Choose Your Pain”, Tilly was the first person to say ”fuck” in Trek.

• Before sitting in the captain’s chair, Rayner does a one handed variation on the Picard maneuver.

• The episode opens on L’ak’s funeral. Because he stabbed himself in “Mirrors”, and then intentionally overdosed on the drugs meant to cure him in “Erigah”.

• The…bridge(?) of the Breen dreadnought appears to have the floating wickets seen in this season’s credit sequence.

• We’ve seen Efrosians before in “Star Trek: The Voyage Home”, and “Star Trek: The Undiscovered Country”, but Hy’Rell is the first Efrosian woman we’ve been introduced to. She has more forehead ridges than the two previous Efrosians, though it's not clear if that's a redesign, or intended to be an example of sexual dimorphism.

• Burnham is very curt with Hy’Rell, cutting the archivist off multiple times as she explains the history of the Eternal Gallery and Archive. As all the lues leading to the Progenitor technology have thus far involved a lesson of some sort, no doubt the lesson being set up here is one about patience, and surely not just a bunch of faffing about before ultimately deciding the real lesson is the importance of self reflection.

• Cherenkov radiation was previously mentioned in “Choose to Live”.

    • In “Choose to Live”, Cherenkov radiation was said result from Tachyons interacting with an atmosphere, while here Tilly claims it is a byproduct of plasma activity.

    • In both cases, the Cherenkov radiation produced a blue glow.

• When Rhys claims the USS Discovery A won’t be able to cloak while in the pocket of the Badlands the Eternal Gallery occupies, Burnham claims that will also be true for the Breen, implying that the Breen’s cloaking device functions similarly to the Federation iteration of the technology.

• Hy’Rell is interested in having Book provide some information about one of the few remaining Kwejian artifacts stored at the Eternal Gallery. Kwejian was destroyed in “Kobayashi Maru”.

• Hy’Rell has the Eternal Gallery lower its shields so Burnham and Book can transport over. We’ve seen that in the 32nd century, transporters are not limited by shields, such as in the episodes “People of Earth” and “There is a Tide…”. Apparently the Eternal Gallery’s shields still block transporters.

    • The artifact is cutting from the a World Root, a system of tree roots that extended around the entirety of Kwejian before it’s destruction, first mentioned in “Kobayashi Maru”.

    • Hy’Rell only says the cutting came in to the possession of the Eternal Gallery, ”long ago,” without being any more specific. Kwejian was a pre-warp society when it was destroyed, though clearly some Kwejian, like Book, made it off world.

• The interior of the Eternal Gallery and Archive was filmed at the Thomas Fisher Rare Book Library at the University of Toronto.

    • The Eternal Gallery’s collection we see appears to be mostly hardbound, paper books. No doubt all the various alien methods of recording information are kept in other wings.

• Hy’Rell claims that the Eternal Gallery has an oubliette. In “Star Trek Nemesis” Riker the Reman Viceroy into a bottomless pit on the lowest deck of the USS Enterprise E.

• The script used in the book, “Labyrinths of the Mind” is the same as what was on the library card that led the Discovery A to the Eternal Gallery, confirming that is the Betazoid language, meaning the first time it was seen was in “Erigah”.

• Burnham’s consciousness is transported into an artificial reality.

    • Captain Picard experienced the end of the planet Kataan from the perspective of a member of that species in “The Inner Light”.

       • Doctor Culber says of the device affecting Burnham, ”It looks like some kind of nucleonic emitter,” and that he doesn’t want to risk severing the beam as it could be fatal. In “The Inner Light” it was a nucleonic beam from the Kataan probe which subjected Picard to his experience.

    • Captain Sisko, Jadzia Dax, Kira, and Doctor Bashir were transported into a Wadi game, Chula, in “Move Along Home”.

    • Rutherford was also trapped inside a Chula game in “In the Cradle of Vexilon”.

    • Harry Kim’s mind was trapped inside a shared consciousness ruled over by an evil clown in “The Thaw”.

• ”Jinaal would have let an itronok eat us,” Burnham recounts the test from “Jinaal”.

• The books accessed by Doctor Derex when she was an archivist include

    • “Comprehensive List of Talaxian Hairstyles”; a multi-volume set

    • “Huypirian Folk Tales”; several Huypirians have been seen severing as personal valets to various Nagi of the Ferengi Alliance

    • “Euclidean Geometry”; this is the first mention of a species called the Euclideans.

• ”Hysperians really know how to party, by the way.” Hesperia is a human colony of, as Rutherford puts it, “ren faire types.”

• ”Someone once told me never turn my back on a Breen.” Rayner shared the Romulan saying first spoken in “In Purgatory’s Shadow” in the previous episode, “Erigah”.

    • The Breen also have a saying; “Never turn your back on the wife of the Scion.”

The 2024 Eisner awards for the comics industry announced the nominees a couple days ago, and the Day of Blood tie-in issue, Shaxs' Best Day by Ryan North and Derek Charm is among the nominees for Best Single Issue/One-shot.

The colourist for the current ongoing Star Trek comic, Lee Loughridge, was also nominated for Best Colouring.

Modiphius' Star Trek Adventures TTRPG is getting a second edition this year, and the last of the sourcebooks for first first edition has been published, so I thought I would go through the entire collection and share some of my favourite art from the game.

• The episode’s title, “Erigah”, refers a form of Breen “blood bounty” first mentioned a couple episodes ago in “Mirrors”.

• The opening shot is of the USS Locherer, first seen in “Jinaal”, and the Terran warp pod that Moll and L’ak escaped with in “Mirrors”.

• It’s Nhan! From Star Trek! Nhan was introduced in “Brother” and is played by Rachael Ancheril.

• ”Last time I saw you, also a personal situation, you fired on Discovery with photon torpedoes, and set off an isolytic weapon.” Nhan is referring to the season four episode, “Rubicon”.

• ”You did this to him!” Moll stabbed himself while in a fight with Burnham in “Mirrors”.

• ”Fierce as a sa-te kru.” This is the first mention of a sa-te kru on screen, but the cat like predator from Vulcan/Ni’Var originated in a six page comic called “When Worlds Collide: Spock Confronts the Ultimate Challenge” written by Alex Kurtzman and Robert Orci, and drawn by Paul Pope that was published in a 2009 issue of “Wired”.

• Throughout the course of the episode, outside of Federation HQ, in addition to the USS Discovery A we see:

    • Two Mars-class starships

    • USS Excalibur - 32nd century Constitution-class

    • USS Credence - Introduced in “Choose to Live”

    • USS LaMar - A ship of the same class as the USS Dresslehaus

    • USS Lochlerer - Merian-class

• The fourth piece of the Progenitor technology researchers’ map piece is now included in the opening credits sequence.

• ”Let’s not forget what happened last time Breen entered Federation space.” The last time we know for certain that the Breen entered Federation space was in “The Changing Face of Evil” when they attacked Starfleet HQ on Earth during the Dominion War, some 834 years ago. It is entirely possible that Rayner is referring to a more recent event that we the audience are unaware of.

    • Later, Tilly claims, ”The last time the Breen paid a visit to the Federation, they destroyed an entire city.” That might be a reference to the attack on San Francisco in “The Changing Face of Evil”, though it would be an exaggeration of the scale of the destruction. And again, 834 years have since passed.

• Rayner evokes the Romulan saying, ”Never turn your back on a Breen.” While in a Dominion prison station in “By Inferno’s Light” a Romulan fellow prisoner told Doctor Bashir that was a saying among her people.

• The Betazoid emblem on the clue that we will learn is a library card, was originally designed by a Trek fan named David Bilic for the “Birth of the Federation 2” mod. It was first seen on screen in “The Star Gazer”.

• The USS Mitchell was first seen in “Rubicon”.

• ”What’s worse than death?”
”This conversation, for starters.”
In “Magic to make the Sanest Man Go Mad”, Harry Mudd claimed that the weaponized dark matter beads that Captain Lorca had were rumoured to be the most painful way to die; now they need to be downgraded to number two.

• Jett Reno apparently makes a cocktail called the Seven of Limes, presumably named for the notable captain of the USS Enterprise G.

• Unlike the 24th century Breen Interceptors, the Breen Dreadnought appears to be more or less symmetrical.

    • It is stated that this Dreadnought is the one Burnham and Rayner saw outside the destroyed Federation HQ in a possible future in “Face the Strange”, though I will be honest, it was too dark for me to make out on the screen at the time.

• Burnham learned that Kellerun was used as a Breen outpost. Apparently that didn’t come up when she did the research in to Kellerun culture she mentioned in “Mirrors”.

    • Does this indicate that Kellerun is not part of the Federation, or is the attack on Kellerun the previous entry into Federation space that Rayner mentioned earlier in the episode?

• Reno claims she had ”tons of contacts in the book trade” 800 years earlier. Discovery and its crew jumped to the 32nd century 933 years earlier. I think it’s safe to assume that Reno was rounding off, however, 133 years is still a pretty big gap. This can only mean that at some point before the jump to the 32nd century, Reno also found herself in the 24th century smuggling books. I eagerly await that spin-off.

• President T’Rina bluffs Primarch Ruhn by claiming the Federation has received an offer from another Breen Primarch for Moll and L’ak. As we all know, Vulcans cannot lie.

    • Vulcans lie all the time.

• ”This bluff wouldn’t fool a hatchling.” Ruhn’s remarks imply that Breen are oviparous.

• Rayner states that Primarch Tahal named her ship the Tau Ceti ”After a lethal viper with a slow acting venom.” It’s unclear if this viper is native to the Tau Ceti system, which can be seen on star charts going back to “Conspiracy”.

• Book is able to get a psychometric reading off the library card to to figure out where the Archive is. This is the second time Book’s extrasensory abilities have been the key to solving one of the clues, the first being in “Jinaal”.

    • The reading from the library card indicates the archive is in the Badlands, a volatile region of space, conceived of for the premiere of VOY, “The Caretaker”, and first seen in the DS9 episode, “The Maquis, Part 1”.

• ”Sell me a goat farm on Bopak III while you’re at it.” Bopak III is the world where the Jem’Hadar first, Goran’Ager enlisted Doctor Bashir to try and use the locally available materials to cure his men of addiction to ketracel white in “Hippocratic Oath”.

• After stabbing himself and intentionally overdosing on medication meant to save him, L’ak dies as he lived. Stupidly.

    • In an interview with TrekMovie, series editor Carlos Cisco said that while Breen are less vulnerable in their solid form -- still susceptible to self inflicted stab wounds though -- the act of maintaining it requires so much energy they are slower, more sluggish, and less intelligent while doing so. This is the form that L'ak chooses to remain in.

• Rayner advocates for firing on the Breen before they can make the first move. in “The Vulcan Hello” Burnham so strongly believed that the USS Shenzhou should fire the first shot against the Klingons that she was willing to foment a mutiny to do so, a fact that she later points out to him.

• Doctor Kovich gives Burnham a list of the five scientists who had the task of researching the Progenitor technology, three of whom we’ve already learned about. The remaining two are a Denobulan, Hitoroshi Kreel, and a Betazoid named Marina DeRex. The first Betazoid we were introduced to in Trek was TNG’s Deanna Troi, played by Marina Sirtis.

• The opening sequence now shows the third map piece being added to the whole.

• Burnham gives Tilly a rundown of what she learned about the pre-warp Halem’nite language. It was established in the series premiere, “The Vulcan Hello”, that Burnham’s expertise is xenoanthropology.

    • The episode is named for the whistlespeak that the Halem’nites use to communicate over long distances. This mode of communication is used briefly early in the episode, and never again, including during the climax that relies upon a child communicating with their father.

• When Burnham and Tilly beam down to Halem’no, they arrive with markings on their foreheads to appear as Halem’nites. Starfleet officers being surgically altered to blend in with the locals during an away mission goes back to “The Enterprise Incident” when Captain Kirk was disguised as a Romulan, but this is the first time we’ve seen those alterations be applied mid-transport.

• “Turns out you have a perfectly typical, healthy, and rather handsome human brain.” Doctor Culber’s body was recreated out of mycelial network fungus matter in “Saints of Imperfection”.

• “I’m the queen of endurance.” In “Point of Light”, Tilly, with some help from a jahSepp inhabiting her body, set a course record running a half-marathon through the corridors of the USS Discovery.

• The weather tower control board features Denobulan script, first seen in “Stigma”.

• It is revealed that the winner of the Journey of the Mother Compeer gets sacrificed to the gods in order to bring the rain.

    • There are a few examples of sentient beings being ritually sacrificed in Trek, though most are talked about as something done in the past, such as on live sacrifices to Molar on “Qo’noS” being mentioned in “Will You Take My Hand?”, or the inhabitants of the planet featured in the VOY episode, “Muse” having replaced live sacrifice with theatrical plays.

    • We saw that Kelpiens culture viewed their being taken by the Ba’ul as a sort of ritual sacrifice in “The Brightest Star”.

    • In “Life Us Where Suffering Cannot Reach”, the Majalans regularly sacrifice a child referred to as the ”First Servant” to a slow and painful death to maintain the technology which enabled their civilization.

• The walls of the weather tower’s vacuum chamber are made of solid tritanium, and apparently too dense to allow for a transporter lock. The hulls and bulkheads of many Federation starships including the Discovery and the USS Enterprise D were made of tritanium, but did not impede transporter functions.

• Burnham makes the decision to disregard the prime directive as opposed to letting Tilly and Ravah die. Kirk frequently ignored the prime directive to save lives, such as in “The Return of the Archons”, “A Taste of Armageddon”, and “The Apple”. Even Picard violated the prime directive in “Justice” to save the life of Wesley Crusher, and “Who Watches the Watchers” to prevent the Mintakans from worshiping him as a deity.

    • The punishment for violating the prime directive is apparently a significant amount of paperwork. In “Bread and Circuses” it is stated that Starfleet officers swear to die before violating the prime directive.

• The handle Ohvahz uses to open the sacrificial vacuum chamber functions very similarly to 24th century manual access clamps, such as the ones seen in “Star Trek: First Contact” and the LDS episode, “First First Contact”.

So, the plot in season five of Disco is hunting down clues left behind by scientists who uncovered the technology left behind by a precursor race of alien beings who panspermiad their genetics all over the galaxy, resulting in all your favourite humanoids, like humans, Klingons, Romulans, and Cardassians, as seen in the TNG episode, "The Chase".

And the antagonists of the season are not actually the tragically dumb young lovers, Moll and L'ak, but instead appear to be the Breen. We've learned Breen are, as Captain William Shaw might say, goo people. Or at least they're semi-transparent so long as they're within the confines of their refrigeration suit. If L'ak is any indication they can take a more solid, humanoid form, but the Breen appear to prefer to be Sour Patch Kids.

I'm going to speculate that we will learn that the Breen are not actually one of the species who resulted from the Progenitors seeding the galaxy, and as such the Progenitor technology is of limited use for them.

I've known for years that Gene Roddenberry wrote lyrics for Theme from Star Trek so that he could receive 50% of the royalties, but it never occurred to me that I should try and find out what those lyrics were. However, the lyrics did come up recently in a nerdy trivia show I watch, "Uhm, Actually", and now that I know them, I thought it important to share.

Beyond the rim of the star-light

My love is wand'ring in star-flight

I know he'll find in star-clustered reaches

Love, strange love a star woman teaches.

I know his journey ends never

His star trek will go on forever.

But tell him

While he wanders his starry sea

Remember, remember me.

• The episode title references the mirror universe, a dark reflection of the familiar reality of Star Trek where humans, or Terrans as they’re more commonly called there, evolved to be more sensitive to light, resulting in everyone tending more towards malevolence, and barbarism, and queer coded villainy. Other episodes involving the mirror universe that reference mirrors, include:

    • “MIrror, Mirror”

    • “Through the Looking Glass”

    • “Shattered Mirror”

    • “In a Mirror, Darkly”

    • “In a Mirror, Darkly, Part II”

• Despite not being Starfleet, Book apparently keeps a personal log. He records the stardate as 866282.9.

    • Other non-Starfleet personnel whom we know kept logs include: Neelix, Seven of Nine, and T’Pring.

• The digital ”Federation Watch List” wanted poster for Moll shows the emblems of:

    • Starfleet

    • Ni’Var

    • United Earth

    • Trill

    • Fernginar

    • Risa

    • Hornish

    • Orion

    • Andoria

    • We also see Orion and Andorian files on Moll, including Orion and Andorian script, first seen in “Borderland” and “The Andorian Incident” respectively.

• Rayner suggests to Burnham that the mission into the wormhole is too dangerous for the ship’s captain to take themselves. Picard says it’s a general policy in “Time’s Arrow” that the captain does not join away teams, and in “Star Trek Nemesis” Data sites a specific regulation. However, no captain we’ve seen other than Picard really observes this regulation.

• On the other side of the wormhole, Burnham and Book find the ISS Enterprise. The ship’s only other appearance was in “Mirror, Mirror”. For this episode, the Constitution-class appearance seen in both DIS and SNW is used for the ship, and redressed SNW sets are used for the interior.

    • In “Despite Yourself”, a wireframe model of the Constitution-class USS Defiant was displayed aboard the USS Discovery; at that time the ship had been in Terran Empire custody for over a 100 years, and appeared to have some alterations to both the nacelle pylons, and the bridge, but apparently when the Terrans got around to building their own Constitution-class, they opted for a configuration closer to the original.

• It was established in “Die Trying” that ”Crossing between universes has been impossible for centuries.”

• ”That was my brother’s station, aboard the USS Enterprise*.”* Burnham was raised by Sarek after the apparent death of her parents, as established in “The Vulcan Hello”.

    • ”I’m sure he was just as ruthless as the rest of them.” We learned in “Crossover” that mirror universe Spock became High Chancellor of the Terran Empire, after being inspired by Kirk in “Mirror, Mirror” and instituted major societal reforms, making the Empire more peaceful, resulting in it being conquered and enslaved by the Klingon-Cardassian Alliance.

    • Book finds a plaque with the story of the mirror Enterprise claiming that they escaped to the prime universe after the High Chancellor was killed for attempting to institute reforms. Presumably this still refers to mirror Spock, though he’s not mentioned by name.

    • Burnham and Book assume the ”Kelpien slave turned rebel leader” who helped the mirror Enterprise escape was mirror Saru, whom we saw in “The Wolf Inside”.

• Burnham find a plush doll of a mirror universe Gorn. Mirror Gorn, of course, also abduct members of other species to use as host bodies/food on their breeding planets, but in the Terran Empire that is considered to be a cuddly trait.

• Moll and L’ak created multiple holographic duplicates of themselves to stymie Book and Burnham. The Doctor did something similar in “Renaissance Man” by filling the holodock with copies of himself to escape Tuvok.

• We learn that L’ak is a Breen, a species whom we the audience have not previously seen outside of their refrigeration suits.

    • In “‘Til Death Do Us Part” Worf claimed that no one had seen a Breen outside their suits and lived. Though in “Indiscretion”, three seasons earlier, Kira and Dukat did incapacitate some Breen and steal their uniforms to use as disguises, so Worf’s claims are about as accurate as usual.

• In flashback we see a station operated and populated by Breen. Though their helmets no longer resemble something a character might wear during a War in the Stars, the asymmetric design of their refrigeration suits is inspired by what we saw in DS9.

• We learn through the flashbacks that Moll was saving latinum to be able to afford to set herself up on a colony in the gamma quadrant that she had never been to, but was described to her by Cleveland Booker as being the perfect home. In the season four episode, “The Galactic Barrier” we saw Tarka’s flashbacks to his developing a relationship with Oros, and their mutual obsession with finding a way to an alternate universe that was supposed to be a paradise.

• Unlike what we’ve seen of the Enterprise in DIS and SNW, it’s mirror counterpart has been upgraded with the same system aboard the USS Discovery A that belches gouts of fire into the bridge whenever it encounters a bit of turbulence.

• During a scuffle with Burnham, L’ak ends up stabbing himself, an advanced fighting technique usually only attempted by the most feared Klingon warriors, such as Kozak in “The House of Quark”, the Torchbearer in “The Vulcan Hello”, and most recently Dak’Rah in “Under the Cloak of War”. L’ak has not quite yet mastered the move though, as he lived.

• We learn that L’ak “Carries the genetic code of the Yod-Thot. Those that rule.” In DS9, Thot was a rank held by Breen flag officers.

• Book asks Burnham if she wants to give Pike’s catchphrase, “Hit it,” but she declines. Presumably Book looked up the catchphrases used by various captains of the Enterprise at some point.

• Detmer and Owosekun get to head a team to fly the mirror Enterprise back to Federation HQ. Rhys, whom it has been established twice this season in “Jinaal” and “Face the Strange” loves the Constitution-class more than any other ship, punches a bulkhead when he hears the news.

• A gormagander is a colloquial referred to as a space whale, and they were introduced in “Magic to Make the Sanest Man Go Mad”.

• Doctor Culber mentions having died, which he did when Ash Tyler snapped his neck in “Despite Yourself”, his resurrection in “Saints of Imperfection”, and then hosting the Jinaal personality in “Jinaal”.

• The episode was dedicated to Allan “Red” Marceta, a set dresser who passed away in 2022.

• The arms merchant whom we see Moll and L’ak dealing with appears to be an Annari, who were introduced in the VOY episode, “Nightingale”, which I mention only because I believe it is the first time we’ve seen a member of Delta Quadrant species in DIS, though not the first mention.

    • The weapon he acquired for them is a Krenim “chronophage,” or time bug, which presumably would have originated in the Krenim Imperium, also in the Delta Quadrant, as seen in “Year of Hell” and “Year of Hell, Part II”. In those episodes, the Krenim also had a weapon that manipulated time.

    • Rayner establishes that the time bugs are left over from the Temporal War, which was mentioned in “That Hope Is You, Part 1” as being the reason time travel is outlawed in the 32nd century.

• The Emerald Chain were the antagonist organization of season three of DIS.

• We see that the time bug is what Moll put on Adira’s uniform sleeve at the end of the previous episode, “Jinaal”.

• Burnham appears to keep either a copy of the Vulcan Kir’Shara or a similar artifact in her ready room.

• The opening credits sequence has changed to include both the parts of the key that the Discovery crew have secured being inserted into the ring.

• Burnham and Rayner find themselves being transported between multiple points in the USS Discovery’s existence.

    • The Discovery following Burnham in the Red Angel suit to the future in “Such Sweet Sorrow, Part 2”.

    • The construction of Discovery apparently in drydock in San Francisco. The first time we saw a starship being constructed at a ground facility was the Kelvin timeline USS Enterprise.

    • Stardate 1051.8, which was the stardate Burnham recorded in her log in “Such Sweet Sorrow” at the beginning of the episode when they’re preparing to abandon Discovery and destroy it, somewhat before the battle with Control depicted here begins. That battle was in “Such Sweet Sorrow, Part 2”.

    • Stardate 865422.4. Not a stardate previously given, but apparently during the Emerald Chain attack on Discovery in “There Is A Tide…”

    • 27 years in the future.

    • Some point after Discovery arrives in the 32nd century in “Far From Home”, but before the retrofit in “Scavengers”.

    • After Burnham becomes captain in “That Hope is You, Part 2”, but before the destruction of Kwejian in “Kobayashi Maru”.

    • Season one between “Context is For Kings” and “The Butcher’s Knife Cares Not For the Lamb’s Cry”.

• The hardhat worn by the technician working aboard the Discovery during construction has the 23rd century symbol for Starfleet’s operations division on it.

• ”Well, he lives outside of time because of his tardigrade DNA.” Obviously. Stamets spliced the DNA of the giant tardigrade with his own in “Choose Your Pain”, and we learned that allowed him to exist outside normal spacetime in the time loop episode, “Magic to Make the Sanest Man Go Mad”.

• The Temporal Prime Directive was first mentioned in “Future’s End, Part II”.

• Zora is listening to a rendition of “Que Sera, Sera”.

• ”Are you stuck in a time loop now right now, Stamets?” He’s not, but Stamets was the only one aware of being stuck in a time loop in “Magic to Make the Sanest Man Go Mad”.

• Burnham runs into her younger self. Other characters have met iterations of themselves via time travel in:

    • “Yesteryear” - Spock

    • “Time Squared” - Picard

    • “Firstborn” - Alexander

    • “Visionary” - O’Brien

    • “Children of Time” - Odo; the Dax symbiont

    • “Wrongs Darker Than Death or Night” - Kira

    • “Time’s Orphan” - Molly

    • “Relativity” - Seven of Nine

    • “Endgame” - Janeway

    • “E²” - T’Pol

    • 2009’s “Star Trek” - Spock

    • “A Quality of Mercy” - Pike

• It’s Airiam! From Star Trek! Despite Airiam’s appearance here taking place during season one, it is Airiam’s season two actor, Hannah Cheesman, under the prosthetics.

• It’s Bryce! From Star Trek! Ronnie Rowe Jr. reprises the role he played in seasons one, two and three, before leaving the regular cast, and appearing in only four episodes of season four.

• Burnham demonstrates her familiarity with Owo by mentioning the operations officer joined Starfleet because she wasn’t able to prevent a childhood friend’s death, something Owo told Saru in “Stormy Weather”.

• Burnham convinces Airiam she’s genuine by telling Airiam she sacrifices her life to save everyone else in “Project Daedalus”, an act that none of the rest of the crew believe Airiam would perform.

• ”You love ships, you love the Crossfield.” “Who doesn’t?” Buddy….

• Rayner has to stick a chroniton stabilizer into a field of accelerated time protecting the time bug with his bare hand for some reason, causing the appendage to age rapidly. Picard accidentally stuck his hand in “Timescape”.
