Heartwarming / X-Men Origins: Wolverine

• Logan's interactions with his supposed father in the prologue.
• It's a small moment, but during that Uncomfortable Elevator Moment with Team X, Dukes chuckled (along with Bradley who more openly giggled) in amusement while observing Wade Wilson's Motor Mouth behavior. It may not be much, but it shows that while there are violent members in the team like Victor and Agent Zero or those who are Only in It for the Money like Wade, there are also genuinely decent-hearted guys among them (Bradley and Wraith are also pretty good guys). Furthermore, it shows how much Adaptational Heroism the film gives Dukes, considering that he's a villain in the comics.
• Logan's interactions with Wraith and Kayla, which include the warmest and biggest smiles he has in the franchise, showing him to be the happiest ever in either timeline. Unfortunately, this being Wolverine, it all goes down the drain soon after.
• Wraith and Blob remained friends after they left Team X; other members had either disappeared under mysterious circumstances or severed ties to each other, but Wraith helped Blob with his weight loss despite being unsuccessful due to Blob's physiology giving him an advantage in matches and the account of Blob's potential eating disorder.
• Bradley's comments before Victor kills him:
  Bradley: I always thought it would be Wade who'd come knocking on my door.
  Victor: Wade's dead, Bradley.
  Bradley: I'm not afraid, Victor. I'm not afraid of dying.
• Logan's interactions with the elderly couple. They see a completely random stranger run into their barn, naked no less. And what do they do? They clothe him, they feed him, and they give him a motorcycle. It makes their deaths pretty tragic, especially considering what Logan just went through.
• Wolverine forgiving Kayla after discovering the reason that she's working for Stryker; he's been holding her sister hostage. And her death. And Logan finding her body, eyes open after bleeding to death; he doesn't recognise her, but still closes her eyes to give her more dignity.
• Victor coming back to save Logan from Weapon XI, telling him "Nobody kills you but me."
• Logan coldly severs his ties to his brother after their battle with Weapon XI, but Victor proves his love for him once and for all:
  Logan: This changes nothing: We are done.
  Victor: No, we're not. We are brothers, and brothers look out for each other. [runs into the sunset]
