Heartwarming / Mockingjay

• Just a little moment, but there's the moment when Primrose wakes up with Katniss in the middle of the night, cuddles under a blanket with her, and helps her figure out how she can keep Peeta and the other victors safe from the rebels at the beginning of the book. We've seen time and time again how much Katniss loves Prim, and it's sweet to see firsthand that it goes both ways.
• Cinna's last gift to Katniss: a collection of outfits he's designed for her when she finally decided to be the Mockingjay.
• The fact that Katniss immediately decides to take up protecting her prep team after she finds them, captive and in terrible condition. "Because if there’s one thing I know, it’s that Cinna would never have approved the abuse of these three, who he managed with gentleness and patience."
• We get a very sweet exchange when Posy asks about Octavia's green skin.
  "It's meant to be pretty," whispers Octavia, and I can see the tears threatening to spill over her lashes.
  Posy considers this and says matter-of-factly, "I think you’d be pretty in any color."
  The tiniest of smiles forms on Octavia’s lips. "Thank you."
• Even with the way it ended, it's nice in parts of the book where Katniss and Gale reconnected as friends, especially the little scene with the berries and their two-man "May the odds be ever in your favor!" exchange.
• Despite being Coin’s Number Two and presumably poised to enjoy the benefits that would come with it should she take power, Boggs goes out of his way to protect Katniss and is one of the few to recognize that she’s a traumatized teenager that deserves patience and compassion. The most he does is sigh when she vomits on him after disobeying his orders, causing his nose to be broken, and making him carry her back to the hovercraft, and his desire to keep her away from the Siege of the Capitol is born not out of malice or jealousy like Coin but out of a genuine concern for her safety and sanity. Katniss’s narration implies that as a father (or grandfather) himself, he’s unwilling to treat her as just another pawn (as opposed to most authority figures on both sides of the war), but rather a human being.
• Before the rescue team leaves on the mission to get the victors away from the Capitol, Haymitch offers to have Katniss drugged so she can sleep through the whole thing. You wouldn't normally consider something like that a CMOH, but consider the context: As Katniss notes, Haymitch has been spending the last few decades of his life trying to find relief from the horrible memories of what the Capitol did to him and the only relief he's ever found is at the bottom of a liquor bottle. Offering to have her knocked out it is a gesture of mercy. Haymitch is trying to spare her from having any additional horrible memories of her own.
• Annie and Finnick's reunion.
  No one seeing them could doubt their love.
  • On a similar note Finnick and Annie's wedding.
    • The people from the different districts doing their best to make the event special. Especially the District 12 people teaching everyone to dance and insisting on a special number of steps for the bridal couple.
  • On a related note to that quote, Katniss makes that comment and then promptly imagines her own reunion with Peeta being just like Finnick and Annie's.
• Delly Cartwright is just the nicest girl in the world. Just as Katniss described her in the first book, she's bubbly, friendly to everyone, and ceaselessly kind. To Katniss' astonishment, Delly talks about how everyone in school admired Katniss for her bravery and hunting skills. She can even help calm down a hijacked Peeta!
• Katniss giving Johanna the bag of pine needles. "Smells like home."
  • Really, the whole slow-build from Teeth-Clenched Teamwork to Fire-Forged Friends that Johanna and Katniss go through during their recovery is pretty heartwarming.
• The can of lamb stew with dried plums.
• Anything from Peeta's slow recovery, but especially:
  Peeta: You're still trying to protect me. Real or not real.
  Katniss: Real. Because that's what you and I do. Protect each other.
  • …and:
    So after, when he whispers, "You love me. Real or not real?"
    I tell him, "Real."
    • Even more so with the implication that the above came after Their First Time.
• It is a Tear Jerker that Gale can't lie to Katniss that his bombs definitely didn't kill Prim, but it was brave of him to admit that they'll never know if it was his doing or not. He loved her, and he let her go knowing it was healthier for both of them.
• Peeta slowly heals from his hijacking to the point where he argues against restarting the Hunger Games and stops Katniss from committing suicide via nightlock berries after she shoots Coin. After several months pass, and he feels well enough, he returns to District 12. At Katniss's house, he brings a wheelbarrow full of primroses and advises her that she needs to start doing her therapy. Katniss starts coming back to life, cutting her nails, and taking her first proper wash in ages.
• One word: "Always."
• Buttercup putting aside his hatred of Katniss in light of Prim's death, crying with her, and protecting her during the night so she can have what's implied to be the first good night's sleep she's had since the war ended.
• The end when Katniss and Peeta's children are playing. One of the chief fears of Catching Fire was that Katniss knew that not only would she be forced to marry Peeta, but their children would be flung into rigged Games. All that sacrifice, horror, and pain wasn't for nothing. She married Peeta of her own free will, and their children, and the entire new generation, will grow up in a world without Games.
  • Neither the end of the oppressing regime, the end of the Hunger Games, nor the end of a life of just barely being able to get by was enough to make Katniss feel like she could start a family safely. What did, in the end? Peeta wanting children so badly. She loves him so much that she is willing to overcome her fears so that he can have the children he longs for. And she did it twice, despite having such emotional difficulty carrying her daughter. And also on the flip side - Peeta chooses a life with Katniss, even though for fifteen years that appeared to mean never getting to become a father. He loves her enough that he would rather have only her than have a family with somebody else.
