* HilariousInHindsight: Thanks to ''VideoGame/FateGrandOrder'', 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 CompositeCharacter of the Horseman and Lobo from Seton's ''Animals I Have Known''... go by the alias "''Rider'' of Shinjuku". They ''were'' a Rider in the first battle or two, then Lobo became the dominant personality and they became an Avenger, which implies that the Horseman is a Rider.
** [[spoiler: Cleopatra]] appears as an Assassin in ''Grand Order''.
** Although the Green Knight himself never appears in ''Grand Order'', Sir Gawain still has his belt as an unlockable skill.
* SugarWiki/MomentOfAwesome: Saber destroying the Dementors.
* TearJerker: 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.
