History Heartwarming / FateZero

* Waver using all his Command Seals to [[spoiler:release Rider from his servitude. Rider refuses to leave and Waver ''breaks down in tears'']]. This just goes to show you that Alexander's [[HeterosexualLifePartners bromance]] transcends time, space, and creed.

* Take a look at Lord Melloi II. [[spoiler:Waver is wearing Alexander's colors.]]

* Speaking of bromances, Saber and Lancer share one throughout the series, up until [[spoiler:his death]]. Both come from similar warrior cultures and backgrounds, and have similar chivalric codes of honor that they prize and hold themselves to as heroes and knights, meaning that finding a worthy opponent cut from the same cloth like they have is a rare and wonderful thing, and a battle against such a hero is something that must be done with the utmost respect and reverence. Each fight between the two only cements this sense of profound respect and admiration they have for one another, as even mid-combat, they extol praise on each other's fighting style, martial prowess, and the tactics they employ against their opponent. And when the battles of the Grail War cool, or they have a moments pause in their duel, they address each other as equals, and the way they speak of the other to their comrades shows just how highly they regard one another as someone worthy of their skills and respect as a hero. At one point, Lancer even admits to Saber that:

** This of course, makes [[spoiler:Lancer's death by forced suicide through Kiritsugu's manipulation]], all the more tragic.

* Episode 25: [[spoiler:Kiritsugu finding a young Shirou in the midst of the fire. Shirou's narration notes that it's more like Kiritsugu is the one being saved rather than Shirou. For a moment, all he can say is "He's alive", sounding just so ''relieved''.]] The final scene of the series is one well-known to the fans of Fate/stay night -- Shirou and Kiritsugu sitting outside on a moonlit night. Kiritsugu tells Shirou how he failed to be a hero and Shirou resolves to be the hero the adult Kiritsugu can no longer be. Kiritsugu smiles and comments that "Now I can be at peace." [[spoiler:He dies right after that.]]
** Even better, the narration during the moment when Kiritsugu finds Shirou is taken straight out of the flashbacks in the VisualNovel/FateStayNight visual novel. It's all the more powerful after [[spoiler:Kiritsugu has come to believe that his life was a waste based on a lie that destroyed everything else he loved for nothing]]. At least he does ''some'' genuine good.

*** Unless you remember [[spoiler:her fate in the Heaven's Feel route]].
** In the same episode: Kariya is finally taking Sakura home. Aoi turns out to be alive. The Tohsaka sisters are shown accepting him as their father. [[spoiler:And then we're brutally reminded that these are just Kariya's dying thoughts.]]
* Saber showing a sense of pity towards Kiritsugu [[spoiler:the underhanded way he dealt with Kayneth]]. Despite her anger towards his actions, she's far from harsh when she answers Kiritsugu's WarIsHell speech and is able to see that there was once a person who believed in righteousness.

* If you're counting out of character moments, the ending of the Einzbern Consultation Room series and it's sudden turn towards a fully self-absorbed ending. Especially the last words between the Grail's Lawyer and Student Number Zero, which makes the normally annoying, depressing, and occasionally funny Tiger Dojo segments of FSN suddenly heartwarming. Zero-chan kept her promise to be[[spoiler:an instructor who corrects bad ends and is kind to Ilya... In her own way.]]
* Waver looking into the bag with the video game Rider bought early on in the series and finding another shirt like the one Rider wears is extremely touching [[spoiler:since Rider is gone]]. He even goes on to play the game...
* Ionian Hetairoi is arguably a Crowning ''Noble Phantasm'' of Heartwarming, since [[spoiler: it's created by Iskander and the armies of Macedonia viewing each other as True Companions to the point they will ''break reality itself'' to fight alongside each other. And one of them looks suspiciously similar to.....WAVER himself!]]

* "Daddy loves you, Illya" mixes this with highest-grade TearJerker. [[spoiler: Kiritsugu feels no qualms coldly denying the Grail in spite of it bearing his wife Irisviel's face. But Illya? The Mage Killer cannot bring himself to be cruel towards his baby girl, even a hallucination of her.]]

** Waver Velvet's loyalty is so fantastic to Alexander that Gilgamesh wishes for it to continue, for it brings beauty to his world. That is respect.

* Every moment with Kariya and Sakura is adorable.

* Waver using all his command spells to [[spoiler:release Rider from his servitude. Rider refuses to leave and Waver ''breaks down in tears'']]. This just goes to show you that Alexander's [[HeterosexualLifePartners bromance]] transcends time, space, and creed.

* The scenes used during the [[http://a.pomf.se/okifmu.webm second ED]], showcasing the development of Irisviel and Kiritsugu's relationship status going from "Magus Killer and Homunculus" to "Loving Husband and Wife" definitely counts as one.

* "Daddy loves you, Illya" mixes this with highest-grade TearJerker. [[spoiler: Kiritsugu feels no qualms coldly denying the Grail in spite of it bearing his wife Irisviel's face. But Illya? The Magus Killer cannot bring himself to be cruel towards his baby girl, even an hallucination of her.]]

** That's nothing. [[spoiler:Take a look at one of the soldiers shown in Ionian Hetairoi. [[FutureBadass Look familiar?]] [[UndyingLoyalty Loyalty that surpasses time and space]] indeed.]]
