Heartwarming pages never use spoiler tagging — so beware of unmarked spoilers
Issue 1
The fact that in spite of Peter's life potentially diverging heavily due to never having been bitten by the spider and never becoming Spider-Man, he and Mary Jane still managed to find one another, fall in love, marry, and start a family.
J. Jonah Jameson is a lot nicer than his other selves, having a rather vitriolic but still close friendship with Ben Parker, and is shown to be an uncle-like figure to Peter, giving him his tie when the Parkers head to the memorial service.
Despite Peter's fears of his life changing, when MJ asks about the possibility of their relationship changing, he makes it clear without any hesitation that nothing will change for them.
For decades, one of the typical to the point of cliche characteristics for Mary Jane has been her struggle with accepting Peter's life as a superhero and has actually been the cause of their break-up in several mediums including the mainstream version. Here its all but stated that MJ knows what Peter is going to do and fully supports him the same way he did when she quit her job to start her own business.
The exchange between Peter and his son Richard when the former jokingly calls the latter "a ridiculous kid" for being so engrossed in reading the unedited version of A Tale of Two Cities. Richard's response is to point that his father shouldn't complain since Peter made him that way and he (Rick) is cool with that. Once again Peter is proven, regardless of which universe, to be fully capable of being a fantastic father, something that MJ herself points out to him later.
There has been speculation that Peter's I Work Alone mentality even after becoming an Avenger was in part because he was an introverted nerd in high school and is one of the key issues for him in his adult years. The idea that his son is not only an out and proud nerd but cites his father as the reason for it speaks volumes for their relationship and Peter's abilities as a parent.
Ultimately, rather than receive a painful lesson in responsibility that causes Peter to become Spider-Man, this version of Peter stands out by choosing to become Spider-Man, despite having a lot to lose, because he knows that the city needs a hero and it's his responsibility to become one.
Issue 2
Upon stumbling home one night after being humiliated by Shocker, Peter ends up being confronted by his youngest daughter, who has expressed a fear of Spider-Man earlier. When he sees her tearing up and clearly terrified, he doesn't hesitate to unmask and reveal his identity to her, all to make sure that she's not afraid of him. And May is implicitly the one who inspires Peter to change his suit to something not as menacing looking, by leaving a picture of a red and blue spider on the fridge.
Peter's inner dialogue: So in the last few days, I've not only managed to get my butt kicked. Twice. But I also accidentally revealed my secret identity to my kid. Worse than that ... I scared her. Not good, Peter. Not good at all. Face it. You might not be cut out for this... [Spots May's photo of a spider on the fridge] May's note: Dad, I drew a picture of your spider. I hope you like it. You're the best! Love, May Peter's inner dialogue: ... or maybe I'll give it one more day.
For fans of Avengers: Endgame, just like with the infamous "Hail, Hydra" line, the writers managed to take the three most hated words in the Spider-Man fandom and turn it into something that tugs at your heartstrings.
Issue 3
The first four pages delivers on Peter and May's relationship when they go to the roof for some Daddy-Daughter bonding time: consisting of a Costume-Test Montage where Peter pitches some ideas for his suit. The one that May likes the most? The classic and iconic red-and-blue Spider-man costume! Then they decide to "take it for a ride" via some web-swinging through the skyline with May getting a piggy-back ride from her father.
When Peter encounters the Green Goblin, the latter comments on the suit calling it interesting with the implication being he was being sarcastic about the design.
Green Goblin: I bet some people think its cool. Peter: [Annoyed]..... That's because it is cool.
Issue 4
Harry's justification for letting Gwen know about his double-life as the Green Goblin is that he loves her and doesn't want to keep secrets from her.
Peter and MJ's discussion after the dinner.
Peter: What'd you think of what they were saying? MJ: About? Peter: The world needing heroes. MJ: What do I need heroes for, Peter? I've got you.
