** For Gilles, she is sad seeing what become of Gilles (Caster) and reassured that Gilles (Saber) that she will always be there to pokes at his eyes, referencing the ''Einzbern Consultation Room'' OVA. And if she has an attack chain against either of them where the second attack is either an arts or quick card, ''[[https://m.youtube.com/watch?v=4wMLu9YyaLo she does exactly that''. '''''While smiling'''''

** For Gilles, she is sad seeing what become of Gilles (Caster) and reassured that Gilles (Saber) that she will always be there to pokes at his eyes, referencing the ''Einzbern Consultation Room'' OVA.

** She appears as a BonusBoss in SE.RA.PH as MONSTER after clearing all event missions, similar to her bonus boss status back in ''Fate/EXTRA''. [[spoiler:She turns into Saber Shiki after the first phase of the fight, paralleling how she had done so in ''Paradox Spiral'' after being sealed by Araya.]]

** The BonusBoss for this event is the BonusBoss from ''Fate/EXTRA'', MONSTER [[spoiler: AKA [[Literature/TheGardenOfSinners Ryougi Shiki]]]].

* When most Servants end up on a Hawaii vacation again during [=ServaFes=] 2023, Bazett is found selling popsicles on the beach, just like in ''Prisma Illya''.

** In Medea Lily's Interlude, she and Astolfo continue their rivalry from the ''Capsule Servant'' minigame and ''Apocrpyha'' in general. She's also shocked at seeing another version of ''that'' pink-haired Servant.

---> "I once heard of a happy-go-lucky Rider... No, wait, that was [[LightNovel/FateApocrypha an Apocrypha]]. Well, I guess that itself is a distant 'if.'"

** That Reines is a Rider means she's weak against Gray, who's an Assassin; in ''LightNovel/LordElMelloiIICaseFiles'', Reines is a jerk to most everyone but Gray, who she teases affectionately while claiming it's part of her usual sadistic behavior.

* When Gilles de Rais (Caster)'s encountered in the Prison Tower event, he declares that he'll offer up the ultimate COOL to God, referencing his partnership with Ryunosuke in ''LightNovel/FateZero''. He also sometimes yells COOL when activating his Phantasm.

** His Ascension material is a blood-stained leaf. This is the catalyst used to summon Siegfried in ''LightNovel/FateApocrypha'', which is the leaf that stuck on his back when he bathed with Fafnir's blood, creating his AchillesHeel.

** His Bond Craft Essence illustrates a piece of Iskandar's cape, the catalyst for the latter's summoning in ''LightNovel/FateZero''.

** When Reines and Gray are introduced as Servants, they form a class triangle with him that reflects their relationships in ''LightNovel/LordElMelloiIICaseFiles'': Lord El-Melloi II is a Caster, making him vulnerable to Reines as a Rider, who always has the upper hand over him; Reines in turn is vulnerable to Gray as an Assassin, Gray being the one person Reines treats with any measure of affection; and Gray is vulnerable to Lord El-Melloi II, her mentor.

* Hassan of the Hundred Personas' Zayed the Base aspect is noted for his dancing skills by Nero and Mata Hari who both want to challenge him in a dance contest despite the fact that dancing is hardly his area of expertise. This is a reference to his dance-like dodging in the second episode of the ''LightNovel/FateZero'' anime.

** Her animation update alters her attack animations to be more in-line with her ''LightNovel/FateApocrypha'' fighting style. Most notably, her Extra Attack has her grab her target from behind and slash at their throat, a move she attempted against both Mordred and her master during their brief fight in that series.

* The brutalities done by the citizens of Agartha towards the slaves made Astolfo temporarily remember [[LightNovel/FateApocrypha his time being stuck with an abusive, sadistic Master in his original debut]], but he quickly brushed that aside.

* The final shot of the trailer for the Indian Lostbelt is a scene of Karna standing on the ground while Arjuna flies over him in the sky, showing the difference in power between the two. The shot is almost identical to one from Karna vs Sieg in the ''LightNovel/FateApocrypha'' anime, only this time Karna is the weaker one on the ground instead of the stronger one in the sky.

** BigBad Justeaze being mistaken for a darkened version of Irisviel won't exactly come off weird when you remember that [[spoiler:in the climax of ''LightNovel/FateZero'', Iri's corpse was possessed by Angra Mainyu while the Grail's contents were spilling out and causing destruction, and it later impersonated her while conversing with Kiritsugu and Ilya.]]

** The BonusBoss for this event is the BonusBoss from ''Fate/EXTRA'', MONSTER [[spoiler: AKA [[LightNovel/TheGardenOfSinners Ryougi Shiki]]]].

* The final fight with Amakusa Shirou Tokisada in "Inheritance of Glory" involves fighting a team of Shirou, David, Benkei, Berserker Kintoki, and St. George, the later four being Servants cut from the original ''LightNovel/FateApocrypha''.

** Lady Avalon claims to be Merlin's little sister. While she's obviously just Prototype Merlin under a different name, Merlin actually ''does'' have a sister in several Welsh legends: her name is Gwenddydd, and like her brother, she's usually depicted as a skilled prophet.
