- What would the worth of Don Quixote's first manuscript be in a world where the book itself was never published?
- The Ministry's phones in the Philippines stop working on June 12, 1898 because that day the independence of the Philippines was proclaimed. However, Spain did not recognize that independence and did not evacuate the Philippines until early 1899.
- When rewriting Don Quixote, Cervantes somehow can't remember in which town did he set it and chooses to start the book with "In a place of La Mancha, the name of which I don't want to recall...". Basically, this means that the manuscript Walcott bought from him is now worth nil, since it has a different beginning.
- Amelia uncharacteristically commits mistakes that compromise the mission in both episodes featuring Lope de Vega, both times because she falls for Lope's Chick Magnet. In this way, Amelia can be compared to Nise, the smart, educated lady in Lope de Vega's own La Dama Boba ("The Foolish Lady") who seems to become dumber as she is courted by a man. Fittingly, she reads La Dama Boba at the end of one episode, and the title is dropped before she goes to see Lope in the second.
- Rogelio Buendía, the Ministry agent who was tasked with replacing El Cid, comes from the Francoist regime days (in fact, he was filming the original Cid as documentation for the semi-propagandistic 1961 film starring Charlton Heston) and the Cid he tries to live as is the legendary one that appears in Medieval epics, rather than the purely historical one, because he knows no better. As a result, the legendary Cid ultimately arises from Buendía's own actions, rather than their supposed historical inspirations.
- Napoleon's claim of speaking Spanish "in private" is an obvious Take That! to José María Aznar's 1996 claim that he spoke Catalan in private, because he needed the vote of the Catalan nationalist representatives to become prime minister. However, the fact that Napoleon was from Corsica, which historically had been subjected to a great deal of Spanish influence (despite never being administered by Spain), to the point that Corsica's flag
has its origin in Aragonese heraldry, makes his fictional self's claim not as unlikely as it appears at first. - A really obscure one is that Marshal Michel Ney is portrayed as being completely bald, while portraits of the era show him with a full head of hair. Peter Stewart Ney was an American that claimed to be Michel Ney and said that he had faked his historical death by firing squad. P.S. Ney was bald, and he claimed that all of his Marshal's portraits were wrong.
- Since the Don Quixote we know is not the first draft, we can conclude that the semi-biographical Story Within A Story The Captive's Tale was included by Cervantes to make up for the failure of his theatrical production, The Baths of Algiers.
- After learning that the 1604 actress he has to seduce is named María and that her husband is José, Pacino quips that the only thing missing is Baby Jesus. What's Pacino's birth name? Jesús Méndez.
- Episode 19 seems to play with the idea that Lombardi stole Columbus' idea of "going west to reach the East". But when they meet, Lombardi is actually bent on helping Columbus with his plan, so, why would he steal the idea? Because the Portuguese assassins that Lombardi's daughter accidentally meets on her way back to the time door probably captured her and forced her to take them to Columbus and then murdered the sailor, prompting Lombardi to carry out Columbus' fated travel.
- In "Time of Legend", when general Spínola screams 'Yippee ka yay' it takes a new meaning once you realise the actor who plays him was the one who voiced Bruce Willis in the Spanish version of "Die Hard".
- By killing Thibaud in that inn, Alonso just made sure that the French slaughter everyone in that village. At least El Empecinado is in a 21st century hospital while they are busy!
- From Maite's POV, the last thing she saw before her death was a surprised Julián (who should have been at work at the time) driving a car with another woman.
- Amelia's daughter no longer appears in the photo with Julián... which means her granddaughter Silvia may never be born either.
- And, with Julián's death, there's no way to know what's going to happen with Silvia.
- A lot of missions revolve around the idea of saving a historical figure from an early death. But it could be just as conceivable to have a mission where the objective is to ensure that historical figures die when they should.
- Given that, whenever a time traveler makes a massive change in time, only those who were traveling know the true history... who's to say how many times it could have happened?
