Heartwarming / Courier's Mind: Rise of New Vegas

• Despite giving Doc Mitchell a lot of flak at the start, The Courier immediately turns his tone around, after the good doctor gives him his Pipboy without even considering asking for payment.
• The Courier completely going out of his way and trying to infiltrate The Powder Ganger's HQ among other things, just to save Good Springs. Living proof that helping someone in need can payoff.
• After giving his usual "pleasantries" upon meeting Boone, The Courier ends the conversation by giving Boone his sympathy for what happened to his wife.
• After repeatedly casting doubt on Boone's abilities as a soldier, the Courier admits he may have been wrong, after seeing Boone shrug off a hit from a nightkin.
  • Later in the same episode, after The Courier tries to help ED-E realize Johnson Nash was planning on scrapping him, Boone tells The Courier to back off to spare the little robot's feelings.
• When Jason Bright thanks the Courier and says it's thanks to two humans (the other being Chris) that the ghouls journey can be made a reality, the Courier quickly corrects that their were three humans that helped them, including his companion Boone.
  • He also tries to call out Bright for taking advantage of Chris's delusions while knowing he can't take him with them after he's served his purpose, despite (understandably) thinking Chris is a prick.
• Despite being pissed about Boone dragging him to the frontlines of the war between The NCR and Legion, when The Courier finds out Ranger Milo plans on just mercy killing NCR prisoners being held by the Legion forces in Nelson rather than risking a rescue mission, The Courier once again goss very much above and beyond to be the hero and helps NCR take the whole town, just to save a handful of soldiers.
• The Courier and The Great Khans who had tried to kill him, managing to come to an understanding, due to Benny's betrayal of the latter. The Courier even calls out an NCR Leutenant for trying to go after them anyway, convincing him to disobey his orders and let them go.
• After pulling out the dead body of a woman's husband for her, The Courier asks Boone about his wife and we get a pretty meaningful exchange between them.
• Surprisingly, the Quit Your Whining moment The Courier gives his companions in S8 E2 after they start talking about their families ends in a touching way.
  The Courier: Bottom line is, you are all full grown adults with your own lives. Even if your parents were still around at this point, they would have to accept you the way you are - you don't need to prove jack shit to them! If anything, they're the ones who should be judged. So cheer up, all of you! For all you know, they're watching you in the afterlife right now giving high-fives to each other.
• The Courier standing up for ED-E, after Arcade not so subtly tries to convince him to kill the latter.
• The Courier snarks at First Sergeant Astor after Astor congratulates him for clearing out Cottonwood Cove alone - noting that Astor forgot to mention The Courier's companioins.
  The Courier: Notice how I said we killed everybody there, not I killed everybody there.
• When Boone finally tells the group about what he did when his wife was taken by the legion, Arcade stands up for Boone when Veronica criticizes him for it.
  • After finally getting the full story, The Courier resolves to help Boone work through his issues, whether he wants to face them or not. And after it's all said and done at the end of the season, The Courier and to a lesser extent the other companions make it clear they'll have his back.
  • On a more subtle note, despite having a small undercurrent of hostility between them, even Veronica seems to have warmed up to Boone.
• Ending line of season 12, episode 10, after Veronica fails to convince the Elder and resigns herself to face their end by their side:
  The Courier: By the way, just so we're clear: the Brotherhood is not all you have. Not anymore.
• The ending monologue of season 13, where the Courier finishes off his Heroic Self-Deprecation with a long series of messages to his followers wishing them well and apologizing to them for being a jerk for the duration of their companionship.
