Given the plot, the title probably alludes to the Korean zombie movie “Train to Busan”. Also, actor Ken Foree played Peter Washington, the lead character in 1978’s Dawn of the Dead.

The stardate is 2449.1, and Enterprise is on a routine scanning mission. Pike, for once, refers to the ship as Enterprise and not “the Enterprise”. This is actually the correct naval nomenclature, since you wouldn’t use “the” before a proper name; for example, “Hello, this is the John Doe.”

There’s big hunk of text on screen which these old eyes can barely make out. We get the scientific name of chimera blossom, or chimera weed, chimeralca oleracea (the second word just means “herb” or “vegetable” in vulcanate There’s a big hunk of text on screen which these old eyes can barely make out. We get the scientific name of chimera blossom, or chimera weed, chimeralca oleracea (the second word just means “herb” or “vegetable” in Latin - brassica oleracea is cabbage). The science report is dated 2257 and talks about chimera as sparsely distributed throughout the galaxy, a source of omega-15 fatty acids and antioxidants and its use as a medicinal herb in many areas near the “Klingon region”. It is also used to treat hypotension and “diaphorous ceti syndrome”. It has the highest level of “vitamin alpha 15” among green leafy vegetation, chock-full of other vitamins and minerals (including iron vulcanate) and plays a role in “vision healthy mucus membranes” and protection from lung and oral cavity cancer. brassica oleracea* is cabbage).

Ortegas says it’s been a long time since she flew into disputed Klingon territory, alluding to her service during the Klingon War (SNW: “Those Old Scientists”, “Under the Cloak of War”).

Pike mentions a mission he and M’Benga were on in Zeta Borealis. Zeta Coronae Borealis is a double star system about 520 ly away from Sol. M’Benga blamed his nausea on Vedalan cigars. The Vedalans (TAS: “The Jihad”) are a felinoid species and the oldest spacefaring race known.

M’Benga translates the Klingon warning as “Go Back Or Die”. The text is not in the usual pIqaD script used in transcribing Marc Okrand’s tlhIngan Hol but one that was created by Geoffrey Mandel for his fan-made USS Enterprise Officer’s Manual in 1980 and is meant to be a one-for-one substitution for English. Since this particular alphabet has no “c” equivalent, the warning actually reads “GO BAOOK OR DIE” and the words under that are (taking “oo” as “c”) “By Order of the Klingon High Council”. My very basic Hol would translate “Go Back or Die” as yiHeD ghap bIHegh.

I missed this last time, but this season’s title sequence includes shots of a Klingon D7-type cruiser, a shuttlecraft and Starbase One.

There is no animal life on Kenfori. The last planet I recall from Star Trek that had no animal life was Omicron Ceti III (TOS: “This Side of Paradise"), but that was because the planet was being bathed in Berthold rays, which disintegrate animal tissue with prolonged exposure.

M’Benga has three ex-wives, four if you count an annulment. His enjoyment of fishing was revealed in SNW: “Spock Amok”.

M’Benga points out that certain poisons have medicinal value. To be fair, the opposite position is truer. As the Swiss doctor Paracelcus (said to be the father of pharmacology) opined in 1538, “All things are poison, and nothing is without poison; the dosage alone makes it so a thing is not a poison.”

The Klingon ship approaching the planet is a D7-type, probably a K’t’inga class since it appears to have an aft torpedo launcher. One was last seen in SNW: “Subspace Rhapsody”. I say D7-type because K’t’inga-classes - first named in Roddenberry’s TMP novelisation, are technically anachronistic in SNW, since they are supposed to be more advanced than the D7s we see during TOS (which only have a forward torpedo launcher). But Temporal War shenanigans, etc. etc.

Pike says the Klingons are hunting them like Skral rabbits. The River Skral is a river on Qo’noS (first mentioned in DS9: “The Way of the Warrior”), and features in Klingon mythology as well. Closed captioning identifies the female Klingon commander as Bytha.

Spock says Vulcans can regulate pain via meditation. In TOS: “Operation: Annihilate!” Spock fights through the pain of being infected by a Denevan parasite by chanting the mantra: “I am a Vulcan. I am a Vulcan. There is no pain.”

Christine slaps Spock to snap him out of the meld. In TOS: “A Private Little War” Spock instructs her to hit him to awaken him fully from a healing trance - Scotty stops her, not knowing, but M’Benga finishes the job. The new nurse (first appearing in SNW: “Wedding Bell Blues”) is credited as Ensign Gamble, but I don’t think his name has been mentioned yet on screen.

When Una is briefing the senior staff, we see pictures of the NX-01 (ENT) and Phoenix (First Contact) displayed at the end of the room. Una says that La’an should get what Ortegas is going through, as indeed she should, given her own history with the Gorn (SNW: “Memento Mori”).

Basically, the Chimera Blossom (and now we know why it was named that) allows for hybridisation of different species. In the research facility’s case it hybridised the humans and Klingons with the all-consuming moss, and now M’Beng intends to use it to hybridise Marie’s human genome with the Gorn DNA inside her.

Viridium is a material that can be tracked across star systems. Spock used a viridium patch to track Kirk to Rura Penthe in ST VI. M’Benga was offered a drink by a R’ongovian (SNW: “Spock Amok”) during Spock and Christine’s wedding (“Wedding Bell Blues”), so that’s when he ingested the viridium-spiked olive.

Bytha identifies herself as the daughter of Dak’Rah, and the Champion of House Ra’Ul. Ambassador Rah appeared in “Under the Cloak of War”, where M’Beng killed him - whether it was in self-defence or not is ambiguous.

Ortegas has a ritual of kissing her fist and then knocking on the console for luck. I don’t believe I’ve noticed her do it before.

Bytha says her father was a traitor. As related in “Cloak”, Dak’Rah defected to the Federation following the Klingon War and became an ambassador. Because of this, his House underwent discommendation, which is the equivalent of being excommunicated from Klingon society (TNG: “Sins of the Father”).

Una trying to inform the Klingons that they are on a rescue mission echoes Saavik’s Kobayashi Maru test in ST II, where she gave orders to do the same. Una’s reluctance to raise shields echoes Kirk’s similar reluctance when faced with the USS Reliant in the same movie.

M’Benga finally confesses that he murdered Dak’Rah.

Sto-vo-kor is the Klingon Valhalla, where honourable Klingons who die in battle go after death.

Another quote from ST II, this time from Ortegas: “Klingons don’t take prisoners.” Una’s reference to a warrant officer confirms there are indeed enlisted personnel within Starfleet at this time, as WOs stand in a gap between enlisted and commissioned ranks.
