History Heartwarming / DiabloIII

* Meta-example: The "Kanai's Cube" added in patch 2.3.0 was at first just a new version of the Horadric Cube, but was re-named in honor of Blizzard artist Kevin Kanai Griffith, who lost his battle with cancer in October 2014; in-universe, the Cube is named after "Chief Elder Kanai", a barbarian so strong, many believed he could've been the next inheritor of the title "Immortal King", before Baal's actions led to the decimation of their culture.

** The Wizard and Barbarian empathize with Leah, telling her that just as they find safety in magic and knowledge/Strength of armas, she can find it by building her inn.

* According to his flavor text, [[UglyCute Galthrak the Unhinged]], a non-combat pet, [[BreakingTheFourthWall wanted to be a Rift Guarding]] from the time he was a broodling. He studied for many years, but was ultimately found wanting. But...

* It is possible for two of the same Follower to be present at once, by recruiting the Follower in question and then repeating the part of Campaign Mode where you meet said Follower, and yes unique dialogue exists for it. While it would've been funny to see two of the same character shocked to see one another, the game instead has the two copies treat one another as distinct persons meeting fellow members of their respective organizations; both Kormacs recognize each other as members of the Templar Order, both Lyndons acknowledge one another as members of the Thieves' Guild (and handsome ones at that), and both Eirinas are glad to have a little sisterly bonding together. It's a warm and fuzzy way of implementing DevelopersForesight.

** The Demon Hunter apologizes for their earlier criticism of her "open an inn" idea.
** The Wizard empathizes with Leah, telling her that just as they find safety in magic and knowledge, she can find it by building her inn.

* Haedrig's little arc in Act V involves a young man named Brycen, who you rescue from Reapers as a result of his calls for help reaching Haedrig's ears. Brycen decides to repay Haedrig by helping him, which Haedrig does not take kindly to. After an incident where Brycen loses Haedrig's best hammer and gets yelled at, the player talks to Haedrig asking why he is so hard on Brycen. Haedrig tells them Brycen is a fool, and fools get killed around here. The player notes that Haedrig has lost much in his life (his grandfather, his father, his wife and his apprentice) and perhaps is afraid of losing someone else again. As the player is preparing to battle Malthael, Haedrig has taken Brycen on as his new apprentice. This earns the blacksmith a bit of teasong from the Nephalem.

* Your final conversations with Leah in the Armory as she is trying her hardest to keep the Black Soulstone together with all Hell trying to get in. Turns into a major TearJerker later though when Adria's betrayal goes down.

--> '''Monk:''' Are you crying.

* At the funeral of [[spoiler: Deckard Cain]], Leah bitterly brushes off the attempts of [[spoiler: Tyrael]] at comforting her, rebuking "What would you know about sacrifice?" He took her hand and showed her through his eyes how [[spoiler: he was willing to defy Imperius, and hence Heaven Itself, to give up his status as an angel to protect the humanity he so loved.]] Leah was so moved by this gesture of love and kindness that she shed TenderTears at the revelation.

* In Act III there is a an older soldier and his wife who have several heartwarming conversations. In one she congratulates him for throwing the demons back.

** Made all the more heartwarming by their previous interactions as an [[LikeAnOldMarriedCouple old married couple]], with all the bickering and stinging that that implies. Then [[spoiler: Diablo goes and kills the both of them, and you find the wife's burial wishes, where she very calmly states that they're both dead, and want to be buried together, but without the soldier's sword, because "he won't be needing it anymore"]].

* Mayor Holus' little CharacterArc: When we first meet Mayor Holus of New Tristram, he is stuck in the middle of town, because his cart broke and blocked the street as he was trying to flee. The Nephalem has little respect for a coward who would abandon his town in its hour of need (in fact, if the Nephalem is a Demon Hunter, s/he states outright that he deserves whatever dark fate comes to him). Then we meet him again at [[spoiler: Bastion's Keep]], and he has not changed a bit, still thinking to flee the fortress before the fighting begins. The Nephalem, fed up, gives him [[TheReasonYouSuckSpeech a piece of their mind]], to which Holus replies that he simply wants to live. Later, as the demon attacks wane, Holus has his chance to run, but wonders if [[CharacterDevelopment it wouldn't be better to fight for his life]] instead of running forever. Surprisingly, he keeps to his word and stick around, eventually [[spoiler: dying in the final struggle at Bastion's Keep. A nearby guard says that he never did run, even though he had the chance to at one point.]]

* The game makes it damn clear that [[DudeWheresMyRespect you get your due respect]] [[InvertedTrope for your work]]; if you march through Caldeum after [[spoiler:killing Belial]], the townspeople will be gathered in a crowd to cheer you on, and at the start of Act V, one of the {{Non Player Character}}s will recognize you as the hero of Bastion's Keep.
* Your final conversations with Leah in the Armory as she is [[spoiler:trying her hardest to keep the Black Soulstone together with all Hell trying to get in]]. Turns into a major TearJerker later though when [[spoiler:Adria's betrayal goes down]].
* Freeing Auriel from Rakanoth in Act IV not only restores hope to the angels of the High Heavens, but also to the people of Bastion's Keep, who had been hit with major despair following [[spoiler:Adria's betrayal and Leah's death]].
* Going through Act IV with Lyndon, your character points out his gold gathering has become rather lax. He basically replies [[spoiler:"Screw the gold, this is for Leah." For all his debauchery and shameless come ons, he genuinely cares about her.]]

** To the point that [[spoiler:if he ever has a daughter, he's naming her after her.]]

* Also from ''Reaper of Souls'', you have the chance to help Covetous Shen finally track down the Jewel of Dirgest, and learn more about the legend behind it. At the very end, when speaking to [[spoiler: the ghost of the woman who may in fact be his true love,]] Shen becomes much more solemn and sincere, and gives a rather heartwarming remark:
--> [[spoiler: '''Liria:''' Whoever you are, you have freed me. I am happy to look upon your face.]]
--> [[spoiler: '''Shen:''' And I am filled with joy to have seen yours once again. Farewell, and go upon this last journey.]]

* During the final part of Act V, in order to help you challenge Malthael on equal footing, the souls of those he's imprisoned will aid you. Their spokesperson is [[spoiler: always someone close to the Nephalem--the Demon Hunter encounters the spirit of their long-dead sister, the Wizard meets their most respected teacher in the arcane arts (and also a bone thrown for ''II'' players, said teacher is the playable Sorceress), the Witch Doctor speaks with the representation of their tribal heritage, the Monk reunites with the patriarch of their order, the Barbarian confers with a great hero of their people, and the Crusader has a chance to speak with their predecessor.]] In all cases, the Nephalem show a softer side when talking to [[spoiler: their long-lost loved ones]], no matter how brusque, confident, or aloof some of them might be normally.

* In ''Reaper of Souls'', Kormac's awkward attempts to confess his feelings to Eirena (also doubles as a CrowningMomentOfFunny). Keep in mind that in the regular Diablo III campaign, the player character flat-out ''told'' Eirena that Kormac was in love with her. So she knows, but Kormac doesn't know that she knows. It plays out like a teenage boy trying to work up the courage to ask out a girl that he likes.

* Haedrig's little arc in Act V involves a young man named Brycen, who you rescue from Reapers as a result of his calls for help reaching Haedrig's ears. Brycen decides to repay Haedrig by helping him, which Haedrig does not take kindly to.

Haedrig tells them Brycen is a fool, and fools get killed around here.

As the player is preparing to battle Malthael, Haedrig has taken Brycen on as his new apprentice.

* The game makes it damn clear that [[DudeWheresMyRespect you get your due respect]] [[InvertedTrope for your work]]; if you march through Caldeum after [[spoiler:killing Belial]], the townspeople will be gathered in a crowd to cheer you on, and at the start of Act V, one of the NPCs will recognize you as the hero of Bastion's Keep.

* In a random quest during Act V, you can enter one of the houses in Westmarch to find a sorcerer attempting necromancy to return the souls stolen by Malthael's angels to their bodies. Yes, this approach [[GoneHorriblyWrong goes horribly wrong;]] yes, you end up having to [[EverythingsDeaderWithZombies fight off a bunch of zombies;]] and yes, the sorcerer [[DidntSeeThatComing should have seen this outcome coming,]] but with [[DarkerAndEdgier all the horror running wild in Act V]], [[HumansAreBastards and given that some of the NPCs you encounter in this act are selfish and nasty]], it's nice to see some folks still trying to help others.
