Heart Warming / Jonathan Joestar, The First JoJo

General

• Jonathan is pretty much a walking Heartwarming Moment. Despite everything he's been through, he remains positive and optimistic.

Chapter 3: Grandson Troubles

• Jonathan's utter delight at the revelation that he has a grandchild:
  So that's why he had that strange feeling earlier. The feeling that he knew the person before him. He then clasped his hands together, a very sudden smile forming on his lips. "It is true! I have a grandchild! My very own grandchild! Why, I'm so happy!" He lunged forward, grabbing an unsuspecting Joseph, and pulled him into a tight hug.

Chapter 5: A Gang-Star's Dream

• The scene where Giorno reveals to Jonathan that he's his son:
  He didn't speak, his throat was far too dry and his eyes were already blurring with tears, but with shaky hands, he gently placed his semi gloved hands on Giorno's shoulders, and it took all the blonde's willpower not to flinch. Damn it, Jonathan was gonna use Hamon on him and he would have to use his Stand and fight him and Jotaro was gonna fight him too and Jonathan would hate him forever and-

  Oh. He was being hugged.

  Jonathan pulled him forward gently, arms coming to wrap around Giorno's back as he was nestled softly into the Hamon user's chest. Giorno tensed, he wasn't used at all to this sense of comfort or love, but when Jonathan whispered hoarsely, tears starting to flow down his cheeks, "My son..." He meekly wrapped his arms around Jonathan's torso, his own eyes starting to blur with unshed tears.

  "I'm sorry, for not being there for you." Jonathan whispered, cheek nuzzling against Giorno's forehead, and the latter's arms were tightening around Jonathan's back, "I don't know what to say, it's all so very sudden. I know this must be very hard for you, to meet a complete stranger and to learn he is basically your father, and then to learn such truths of the man you knew your whole life to be your father. But I'm forever grateful fate has allowed me to meet you, even if it was through such bizarre circumstances."

Chapter 6: Brownies And Cola

• Jonathan giving some advice to Sex Pistol #5:
  The bullet in his hand nodded, sniffling. Jonathan offered him a small smile. "It is alright, do not be afraid to have bravery and stand up for yourself. I know what it is like to feel outcasted, but I know that your friends care about you, and so does that young man." He referred to Mista. "I'm still very confused as to how Stands work, but just know that I'll be here if you need another friend." He smiled.

  Number 5 managed a small, tiny smile and nodded. "T-Thank you..."

Chapter 7: Styling Adventures And Striking Blues

• Giorno giving Jonathan a gift:
  As he watched Giorno go back to his small group of friends, he remembered his clutched hands. He looked back at them, wondering why he had put them in such position. He expected to find the metal and whatever else Giorno had randomly scooped up from the floor, but as his hand lifted, he was shocked when he saw striking blue.

  A single blue rose, without the stem or leaves, was sitting on Jonathan's palm, its petals bright and in full bloom.

  The Joestar was awestruck. How on Earth did Gio just...? But... all he had on his palm was what he had picked off of the floor! Is this a magic trick of sorts? He observed the flower, softly touching the petals with his thumb. That's when he felt a small tickling sensation across his thumb, and soon after, a small ladybug was seen crawling up to his nail.

  "Oh, I didn't see you there." He chuckled, watching the miniscule creature crawl back to his palm and up one of the petals.

Chapter 8: Stars In The Sky

• The sight of the Wintry Auroral Sky in Rocky Mountain Village reminds Jonathan of his past:
  It reminded him dearly of better nights, which were spent stargazing on the grass behind the mansion, blanket positioned under him as he and father hugged cups of hot chocolate, with Danny resting peacefully by his legs.

Chapter 9: B-B-Baby!

• Pretty much any of the scenes with Child!Jonathan, he's just so dang happy and cheerful that it's hard not to smile at his interactions with the team.

Chapter 10: Over Heaven

• During the scene where Jonathan once again blames himself for allowing Dio to survive:
  Jonathan: (After realizing that, had Dio not killed him, then Giorno wouldn't exist) I am a horrible being...

  Giorno: That's not true at all.

Chapter 15: Family Ties Across Time

• Jonathan is such a kind person that even Iggy managed to warm up to him:
  He chatted with some people, laughed with others, introduced himself to a few people, and he even stopped to swoon over and pet a small black dog that Gappy hadn't even noticed was there before. It seemed aggressive at first, but it soon leapt into Jonathan's arms for more thorough petting, the action somehow shocking elder Joseph, the redhead, the guy with no eyebrows, and a man in red, all the while Jotaro just shook his head.

Chapter 19: Nice To Meet You, Again

• Apparently, Jonathan would care for the stray dogs that came across his home.
• Jonathan's reunion with Danny:
  "I-I missed you so much, old friend!"

  Danny kept barking happily and licked Jonathan's cheek, making the Joestar laugh even harder. "Ah, do not worry. These are happy tears!"

• This little moment when Jonathan returns home:
  George: (After leading Jonathan to his bedroom) Sleep well, Jojo.

• After Jotaro opens up about his issues, Jonathan tells him this:
  "Even if I cannot stay here forever, don't ever think you are alone. I'm with you, as is your mother, Joseph, and your friends. I know it is important for you to face your battles on your own, and perhaps you think how you feel is invalid, but it's not! Trust me, you are surrounded by people who understand how you feel, and even if they don't, they will still try to help you! Do not shoulder the burden alone, alright? But if you want to, that is alright too, just remember you have people who would do anything to help you! And even if the world is against you, they will be there for you, just like me."
• As a parting gift, Jotaro decides to give Jonathan a paper about him that he wrote for an assignment.
  A warmth spread through his chest as he took the paper. "Thank you...!" And within a second, Jotaro found himself in a tight embrace, though he wasn't surprised in the slightest, honestly.
• Near the end, there's a small moment where Jonathan finally manages to pronounce Kakyoin's name correctly, when he previously couldn't.
