History Recap / StarTrekStrangeNewWorldsS2E03TomorrowAndTomorrowAndTomorrow

* SpellMyNameWithAnS: Downplayed. It's never been quite clear in canon how Khan Noonien-Singh's name breaks down; one popular (although not uncontested) way of interpreting it has been that "Noonien" is his given name, "Singh" is his surname and "Khan" is a title. This episode establishes it as a given name with a two-part surname, "Khan Noonien-Singh" (like "Una Chin-Riley").

* CanadaEh: As the first ever ''Star Trek'' production with scenes set in Canada[[note]]although many scenes from ''SNW'' and ''Discovery'' have been filmed in and around Toronto[[/note]], or indeed with more than a passing reference to it (aired two days before Canada Day!), the episode goes over several Canadian stereotypes:
** When explaining to a Kirk who's never been on Earth what Canada is, La'an goes through several stereotypical Canadian things.
--->''"You know, maple leaves, politeness, poutine..."''
** Kirk later tries and gushes about poutine being served with gravy.
** Canada's cold weather is brought up, with Kirk complaining about the cold and La'an noting that "It's actually not that bad for Canada".

** La'an's conflict in this episode is an inversion of Kirk's in "[[Recap/StarTrekS1E28TheCityOnTheEdgeOfForever The City on the Edge of Forever]]". In that episode, Kirk had to stop a time traveler from saving the life of Edith Keeler, a good person that Kirk had fallen in love with, because despite her good intentions, the future would suffer if she didn't die. In this episode, La'an has to stop a time traveler from killing Kahn, an evil person who haunted her entire existence, because despite his atrocities, the future would suffer without his influence.

* InfiniteSupplies: The pile of money Kirk hustles at chess appears nowhere near large enough to rent the palatial hotel room he and La'an share, let alone to get to Vermont and back.

* EmbarrassingMiddleName: La'an teases Kirk over his middle name being Tiberius, especially compared to his brother's more more normal middle name of 'Sam'.

* RightForTheWrongReasons: La'an and Kirk conclude the divergening point was a cold fusion reactor exploding. Turns out it was ''actually'' the early death of Khan Noonien-Singh (and subsequently avoiding the Eugenics Wars), the reactor exploding was just method used to achieve that.

* PointOfDivergence: It's quickly established the timeline has changed significantly and not just minor crew changes, the further into the story bigger changes are revealed. Kirk shares that Earth is in perpetual nuclear winter after WorldWarIII and humanity colonized other planets but remained isolationist, a far cry from TheFederation. The first thing La'an and Kirk can confirm is they both remember the terrorist attack on the Ontario bridge, and then they pinpoint a reactor detonation that destroyed Ontario as what made WWIII far worse and resulted in the less idealistic future La'an is from.

* AscendedFanon: This episode basically confirms fan assumptions that time traveling agents have skewed with the original Star Trek timeline periodically but largely resulted in a CloseEnoughTimeline to account for continuity and timeline issues, especially when it comes to Khan and the Eugenics Wars originally taking place in the 90's. Sera expressly says she's been biding her time on Earth since 1992 and almost name drops the Temporal Cold War from ''Series/StarTrekEnterprise'', where this theory came from.

* HitlersTimeTravelExemptionAct: Discussed in relation to Khan Noonien-Singh. By killing him, the Dark Ages humanity suffered under his reign never happened, but Earth was rendered uninhabitable by nuclear war and humanity has become isolationist, all because the Romulans were making sure they didn't advance enough to become a threat to them.

* NoSoStoic: The events of this episode show layers to La'an and finally at the end weeps for her loss.

* ExpendableAlternativeUniverse: Initially, Jim resists the idea of ending his reality, expressing concern for his friends. But he gradually realizes that his world is a CrapsackWorld and gets on board with helping La'an, especially after learning his brother George is alive in her timeline.
