- Hilarious in Hindsight: Thanks to Fate/Grand Order, some of the servants that were added now fall under this trope.
- Lancelot is depicted as a Saber with his black armor from Zero. His Saber version debuts in Grand Order...with white armor.
- Rider is implied to be the Headless Horseman. Grand Order has Hessian Lobo, an Avenger, who is a Composite Character of the Horseman and Lobo from Seton's Animals I Have Known...go by the alias "Rider of Shinjuku".
- Moment of Awesome: Saber destroying the Dementors.
- Tear Jerker: Lancelot and Artoria's mutual anguish when each one realizes the other is also here:
- Lancelot because he's so ashamed of his affair with Guinevere and fearing to fight Artoria - because she can be here only by invocation, so she must be a Servant.
- Artoria's utter horror at the possibility of Lancelot being made into a rabid war machine when she sees him in his dark armor, then her heartbreak because he forgot she actually forgave him in the Fourth Holy Grail War.
- The reason why Harry envied Saber so much? Lancelot was loved by someone. Maybe it was morally wrong to have an affair with a married woman who also was his queen, but Lancelot was actually, genuinely loved by one person.
- What an Idiot!: Assassin's response to the first Command Spell task she's given by her Master:attack Rin, now a Professor at Hogwarts without informing Assassin about any of Rin's skills, attributes or even her assistants, all because Rin wounded Draco's pride by reprimanding his bigotry. When she understandably fails (though not for lack of trying), she reams him out for sending her on a fool's errand.
YMMV / Fate Ingens Cor
