ā€¢ The episode title of course refers to a popular party game. In the PRO episode, ā€œMindwalkā€, the Protogies where had to communicate with Dal using charades, because he didnā€™t learn any Morse code.

ā€¢ Both Nurse Chapelā€™s and Spockā€™s personal logs gives us a stardate of 1789.3.

Episode Stardate
ā€œThe Broken Circleā€ 2369.2
ā€œAd Astra per Asperaā€ 2393.8
ā€Tomorrow and Tomorrow and Tomorrowā€ 1581.2
ā€Among the Lotus Eatersā€ 1630.1
ā€Among the Lotus Eatersā€ 1630.3
ā€Among the Lotus Eatersā€ 1632.2

ā€¢ The USS Enterprise is travelling to the Vulcan system, first seen in ā€œAmok Timeā€.

Ā Ā Ā Ā ā€¢ Alternatively, one could argue that the first visit to the Vulcan system was when the Enterprise visited the planet Delta Vega to affect repairs after sustaining damage attempting to travel through the Galactic Barrier in ā€œWhere No Man Has Gone Beforeā€. Delta Vega is also the planet that Nero marooned prime Spock on (and Kelvin Spock marooned Kelvin Kirk on) in 2009ā€™s ā€œStar Trekā€, and Spock was able to watch the destruction of Vulcan. In an interview, Robert Orci claimed they ā€movedā€ the planet for the film because the easter egg of the name was more important than coming up with a new name fans wouldnā€™t be familiar with.

Ā Ā Ā Ā Ā Ā Ā Ā ā€¢ Both the 2011 Kelvin universe ā€œStar Trekā€œ comic series, and ā€œThe Enterprise Warā€ novel attempt to reconcile this by claiming there are two Delta Vegas.

ā€¢ We learn of the Kerkhov moon, and the fact that there was an ancient civilization there that vanished at one point. Other ancient civilizations which have disappeared from the galaxy leaving behind only ruins and mystery are:

Ā Ā Ā Ā ā€¢ The Greek Gods

Ā Ā Ā Ā ā€¢ The Arretans

Ā Ā Ā Ā ā€¢ The Preservers

Ā Ā Ā Ā ā€¢ The Tkon Empire

Ā Ā Ā Ā ā€¢ The Iconian Empire

Ā Ā Ā Ā ā€¢ The Dā€™Arsay

Ā Ā Ā Ā ā€¢ The Hurā€™Q

ā€¢ The Vulcan Science academy was first mentioned in ā€œJourney to Babelā€.

Ā Ā Ā Ā ā€¢ On Vulcan they preface everything by distinguishing that itā€™s Vulcan because itā€™s important to them that the rest of the galaxy be aware that itā€™s theirs.

ā€¢ ā€What are Korbyā€™s three principles of archaeological medicine?ā€ Spock mentioned Roger Korby is referred to as the Pasteur of archaeological medicine in ā€œWhat Are Little Girls Made Of?ā€

Ā Ā Ā Ā ā€¢ Roger Korby will be Chapelā€™s future fiancĆ©e.

ā€¢ The notion that Vulcans use nasal suppressants to overcome how debilitatingly pungent humans are was introduced in ā€œThe Andorian Incidentā€.

Ā Ā Ā Ā ā€¢ ā€Not to be indelicate, Captain, but the scent of humans is something most Vulcans must becomeā€¦used to.ā€ Spock grew up with a human mother, and human adopted sister.

Ā Ā Ā Ā ā€¢ In ā€œBroken Bowā€ Archer comments that Vulcan females specifically have a heightened sense of smell, but in ā€œThe Andorian Incidentā€ it is a male Vulcan monk who comments that the smell aboard the NX-01 ā€œmust be intolerable.ā€

Ā Ā Ā Ā Ā Ā Ā Ā ā€¢ Later in this episode, Tā€™Pril repeats the claim that Vulcan women are more sensitive to odours.

ā€¢ ā€I am still not speaking to my father.ā€ It was established in ā€œJourney to Babelā€ that Spock had not spoken to Sarek in 18 years, which would mean their communication ceased nine years prior to this episode.

ā€¢ The shuttlecraft Spock and Chapel take to scan Kerkhov is the Cervantes, which was previously used on the mission to investigate the USS Peregrine after it was divested by Gorn hatchlings in ā€œAll Those Who Wanderā€, and transported Captain Pike, Laā€™an, and Doctor Mā€™Benga down to Rigel VII where they lost their memories and were subject to a Starfleet yeoman turned Tyrant in ā€œAmong the Lotus Eatersā€, and maybe they should leave the *Cervantesā€ in the shuttlebay next time.

Ā Ā Ā Ā ā€¢ The Cervantes is also the shuttle Ortegas pilots herself, Chapel, and Uhura in back to the anomaly when they revisit it.

ā€¢ ā€The Vulcan Science Academy would be lucky to have someone of your experience.ā€ ā€œBattle of the Binary Starsā€ established that as of 2249, ten years earlier, Michael Burnham was the only human to have attended the Vulcan Science Academy. However, in ā€œBrotherā€ in 2257, Paul Stamets had accepted a full time teaching position there, so they werenā€™t entirely opposed to the idea.

ā€¢ After the Cervantes crash, Spock had to be healed by the Kerkhovians who made him fully human. In ā€œFacesā€ a Vidiian scientist split Bā€™Elanna Torres into two separate beings, one fully human, and the other Klingon. The Klingon died to save her human counterpart during the escape, and the Doctor was later able to restore Bā€™Elanna to her hybrid self using genetic material from the deceased Klingon.

Ā Ā Ā Ā ā€¢ In ā€œSpock Amokā€ Spock had a dream that he was human, fighting a fully Vulcan counterpart, but he later lied and claimed that in his dream he was the fully Vulcan half.

ā€¢ The episode cuts off before Spock can finish saying, ā€œWhat the fairly intriguing development.ā€ As we all know, Spock was unfamiliar with profanity until visiting Earthā€™s 1980s in ā€œStar Trek: The Voyage Homeā€ despite living on a starship and closely working with one Doctor Leonard McCoy.

ā€¢ As a human Spock chooses to eat bacon despite most Vulcans including himself being vegetarian. In ā€œAll Our Yesterdaysā€ Spock appears to be disgusted with himself for enjoying consuming animal flesh after being transported to the past causes him to regress to an earlier stage of Vulcan cultural development. As we all know, all humans eat meat, and this scene certainly didnā€™t disgust any vegans who might be watching and then later writing a point form list of how the episode ties in to other Trek canon.

Ā Ā Ā Ā ā€¢ According to Tā€™Pol in ā€œBroken Bowā€, Vulcans also do not touch food with their hands, but we see Spock picking up the bacon with his fingers here. Of course, Spock also touched his food with his hands in ā€œAll Our Yesterdaysā€ as well as his marshmallow in ā€œStar Trek: The Final Frontierā€ so perhaps thatā€™s a cultural practice that fell out of usage between ENT and DIS/SNW/TOS.

Ā Ā Ā Ā Ā Ā Ā Ā ā€¢ Later this episode, Sevet does not hesitate to go in on some tevmel with his hands.

ā€¢ ā€I just thought that my field work would be relevant.ā€ In ā€œJourney to Babelā€ Kirk argued to Amanda Grayson that Spockā€™s time aboard the Enterprise was ā€œa better opportunity for a scientist to study the universe than he can get at the Vulcan Science Academy.ā€

ā€¢ ā€She did seem awfully enthusiastic about purchasing dilithium.ā€ The Federation of this era is a moneyless society, as established in such episodes as:

Ā Ā Ā Ā ā€¢ ā€œMuddā€™s Womenā€ - The character of Harry Mudd is transporting three women around to find them husbands out of the goodness of his heart, and lithium miners on Rigel XII offer to give the crystals to the Enterprise for free.

Ā Ā Ā Ā ā€¢ ā€œErrand of Mercyā€ - Kirk intimates to Spock that Starfleet would not be troubled by their potential deaths, because their training cost nothing.

Ā Ā Ā Ā ā€¢ ā€œCatspawā€ - Lieutenant DeSalle says he would make a bet on the effectiveness of their strategy, but there is no money and hence no gambling.

Ā Ā Ā Ā ā€¢ ā€œThe Trouble With Tribblesā€ - Cyrano Jones gives away exotic animals, and no one pays for drinks at the bar, because what would they pay with?

Ā Ā Ā Ā ā€¢ ā€œThe Escape Artistā€ - We see several android duplicates of Harry Mudd captured by concerned citizens intending to hand him over to Federation authorities, because thereā€™s no need to collect a bounty when everything is free. Also, Mudd doesnā€™t complain about Federation taxes, because what would they tax?
