Heartwarming / Diablo IV

• Helping a woman escape Ghuulran and finding that her lover waited for her.
  • The two are found at a village where the escapee is experiencing a flashback and is unresponsive. Her lover brews a tea which helps calm her and assures her she never expected her to be alright after what happened in Ghuulran.
• Bound by Blood. A villager's brother has been accused of helping a local bandit tribe murder several merchants, and he asks you to help him discover the truth. As you investigate, it becomes very likely that the brother is indeed a traitor, causing the questgiver no end of anguish even as he resolves to bring him to justice. However, when you finally find the brother, you find him being tortured by the bandit leader after having protested about the killings. After defeating the bandit chief, the two brothers make up and resolve to go into hiding together and start over in the south.
• Flesh and Blood. As a child, Yonca was sent away from her home after her mother fell victim to the swamp's infection. Returning as an adult, she finds her father had driven her transformed mother away and then committed suicide out of grief. Yonca pays tribute to her parents, but in doing so inadvertently lures her mother out of the swamp. To Yonca's delight, her mother is still human and mostly lucid. The two of them reunite and resolve to continue living together as a family.
• The end of the Heretic questline in Act 5. While it's ultimately a Bittersweet Ending, Aneta does at least acknowledge that you were one of the only ones who helped her and treated her like a human being in her letter.
  • If you do Taissa's post-game quest chain after completing Aneta's, Aneta will be called to the witches' conclave (a silhouette resembling her is seen).
• Sure, it's completely unintentional on Inarius's part, but you realize that the overall actions of the Fallen Angel, no matter the reason that Inarius had for doing them, have (partially) restored humanity's faith in the High Heavens again after Mathael's genocide soured their perception 50 years ago. Perhaps Tyrael's dream of angels and men working together at the initial end of III is no longer such a fool's errand after all...
• In the postgame, if you revisit Cerrigar you'll find that the town is slowly but surely recovering from Astaroth's attack. A pair of villagers will tell you that the Cathedral tried to bribe them with "a wagonfull" of gold for turning you in, but they turned it down because you're a hero to them.
