- The term "Apocrypha" refers to something that is unofficial or obscure. It fits as this series is unconnected to any of the events of Kinoko Nasu's "Fate" series.
- During the ending title Koe, which has the Masters/Servants enjoying a rainy day, Karna is notably not happy about the rain. In Hindu mythology, Karna is the son of the Sun God Surya and rival of the Storm God Indras son Arjuna, and Indra had requested him to handicap himself as a trade for his Vasavi Shakti weapon, thus Karna would bear a dislike towards rainy weather.
- The choice of the story's Ruler Servants (Jeanne d'Arc and Amakusa Shiro) explicit set them up as Foils to each other—with both of them having lived, led and fought in a time of war (i.e. The Hundred Years War and the Shimabara Rebellion, respectively), plus getting martyred/executed for their faith and actions even before reaching the age of 20. The clear difference in characterization (i.e. where they diverge) also gains additional layers with Reality Subtext: after all, Jeanne dies an Inspirational Martyr well-venerated within the Church, in France and the world throughout (plus her side, France, actually won the Hundred Years' War). By contrast, the Shimabara Rebellion (and, for that matter, any hope of Christianity regaining its footing in Japan) virtually died with Shiro and his followers, with Japanese Catholicism run aground, evolving to an extent that it isn't fully understood by other countries' Catholic Churchesnote . Amakusa himself remains unrecognized and even unbeatified by the Vatican City. It's probably no surprise that Jeanne (standing in for European Catholicism), someone whose faith was rewarded, will have difficulty connecting with Shiro (standing in for Japanese Catholicism), who experienced misery throughout the centuries.
- In a similar vein, the new opening to Fate Apocrypha sets up another match between Mordred and Jack—both have Dark and Troubled Past with their "biological" parents, but have better working "parental" figures in their Masters. That said, Reika clearly brings out the further creepiness and inhumanity inside Jack, while Kairi, at the very least, gave Mordred further sense of closure regarding her issues with her father and her rebellion.
- It might seem that Fran was weaker than the Berserkers in the Fate franchise. However, we have to look closer. Both Hercules, Spartacus and Lancelot were either a Semi-Divine or a Badass Normal who had years to hone their skills and power. Fran on the other hand was on Earth for more or less a couple of days, she was emotionally traumatized and yet to gain skills of her own. It leaves little wonder why she lost to Mordred or required some help.
- Studio DEEN's adaptation of Fate/stay night confirmed her gender, of course Mordred would be female. Having two female parents, there is no source of Y-Chromosomes to alter her gender.
- Meta humor here. Kairi saving Mordred with the hydra antidote is often joked as Kairi ascending her to 3rd ascension due to the lack of armour. The reason the joke works well because her 3rd skill which only be unlocked in the 3rd ascension raises defence, NP gauge and clears status aliments, perfect for countering Semiramis' poison based NP.
- Somewhat Fridge Tearjerker, but consider Morgan Le Fay's very brief appearance in the anime for Mordred's past. She sounds abit odd, like she's straining her voice in anger or anguish. However, consider some factors: Morgause, the supposed third sister to Morgan and Artoria doesn't exist in the Fateverse, so all traits concerning her went to Morgan. Including the factor that Sirs Gawain, Gaheris, Agravain and Gareth were her children, alongside Mordred. Now, remember one detail in the Arthurian Legends is that Lancelot (who is confirmed in the Nasuverse to have done the same thing) had killed Agravain, Gaheris and Gareth. The former upon discovering the affair and potentially all three when trying to save Guinevere from execution. Another detail is that after this event, Artoria had given an official pardon to Lancelot and Guinevere, saying "their actions must have good cause". Now look at it all from Morgan's point of view: three of her children were murdered in less than a day, and her own sister pardons their murderer believing that his actions might've had good cause. It's very likely that Morgan was fueled by rage and still grieving for her children, as evidenced by her black robes and veil that can be seen as like a mourning veil.
- Amakusa Shirou being summoned makes some amount of sense, as he was a native to the country where the third Holy Grail War was taking place.
- Waver Velvet still went on to become Lord El-Melloi II even though the Fourth Grail War didn't happen. The Fridge Brilliance kicks in when you remember the paper he wrote (that was ridiculed by Kayneth, the first Lord El-Melloi) asserted that hard work and dedication could allow a magus to overcome the disadvantage of a limited lineage. From the look of it, he was right. Similarly, because the Fourth Grail War didn't happen, Kayneth presumably died in a way that left his Crest intact for transplantation in the next Lord El-Melloi. And seeing as Waver controls a Volumen Hydragyrum...
- Astolfo coming to save Sieg from Karna is actually apt, considering he's a moon-powered Hero going up against a sun-powered Hero.
