Right, right, right, so I was thinking! There needs to be a JoJo OVA featuring young Jolyne sometime before part 4 to portray the angst in her relationship with her father leading up to part 6 as well as to provide a teaser for the part 6 anime. And in a perfect world, this is how it would go:
It would start with Usagi taking a pregnancy test and very nearly crying when she finds that it’s positive. This was, in fact, the third pregnancy test that she had taken that day. She goes to tell Jotaro of the news, that she was pregnant with their first child, and the next few scenes is a collage sequence of Jotaro working to prepare for the baby’s arrival, helping Usagi to arrange the furniture in the baby’s room, paint the walls, decorate, and so on and so forth. And as Usagi’s belly swells with their first child, Jotaro also goes off on his own to complete household chores and to take care of Usagi when she’s feeling crappy because of the pregnancy. Then, Jolyne is born. Jotaro gets to hold her for the first time, and although he doesn’t show it, he’s beside himself with joy. He holds her kinda stiffly at first, because he’s lowkey kinda scared and doesn’t really know what to do, but he’s also fascinated at how small her face is, and her fingers and hands, and feet and toes.
Then Jolyne grows up a little, learns to walk and talk, loves playing outside on the swingset and monkey bars because she is a very active child who tends to run around the house and force Jotaro and Usagi to chase her around and catch her before she gets hurt. Well, she got stuck on the monkey bars once, actually, and cries out to her daddy until Jotaro briskly walks up to her and lifts her off of the bars and sets her on the ground. And once she’s on the ground, she takes off again to the swingset then runs around the yard during a nice summer day. While she runs around in the grass, probably seeing just how fast she can run, Jotaro, who sat on one of the deck seats and read a paper related to work, looks up every now and again and watches with a serene joy in his eyes and a small smile as his daughter has a lot of fun.
Then Morioh comes up. Usagi understands his reason for leaving, but now Jotaro has to explain to little Jolyne that he’ll be away for a while. He kneels down in front of her to be more face-to-face with the child and holds onto one of her smaller hands which rests in his much bigger palm, and he tells her that he has to go away for some time. On some level, she doesn’t want to understand and asks him to promise here that he’ll stay in touch. When he sees the distress on her face, his heart sinks, so he tells her that if she speaks into a conch shell, he’ll hear her from wherever in the world he is, and she readily believes that. She even immediately turns to Usagi and tells her that they need to go to the beach ASAP and look for a conch shell, which elicits a laugh from her mother but she agrees to help Jolyne look for one.
Fast forward to when Jolyne is 14 and Jotaro has been abroad for months with very little word from him to the family. It’s been a few years now since he and Usagi had divorced , and Jolyne feels depressed and angry that her father is absent and that she does all of these things to try to get him to pay more attention to her, but it was useless all along. Even when her mother was on the phone with him, pleading for him to return to Florida to see her when she was arrested for car theft, she knew he wouldn’t come back. She then remembers what her had told her years ago--that if she speaks into a conch shell, he’ll hear her from wherever he is. So, when she returns home with Usagi, she does just that--she takes the conch shell she had kept for years after a visit to the beach with her mom and little sister and speaks into it like it’s a phone. Of course, she doesn’t hear anything but the sound of her own voice flanked by long bouts of silence, and she thinks that it’s silly that she’s doing this childish behavior in the first place until she feels so ashamed by it and upset at her father that she puts the shell away.
Yet, I’d like to imagine that there’s a stand user somewhere that let Jotaro hear her talk into this conch shell all along, but we’ll only hint at that and leave it unconfirmed at best.
Fast forward to just before the start of Stone Ocean, and as Jotaro packs up his luggage to board a flight to Florida, he fondly looks over a picture of Jolyne when she was a little girl and happily eating ice cream in the summer. He keeps this picture with him at all times to look over whenever he needed comfort. And the rest goes from there.
And maybe if we’re lucky, Araki would be kind enough to do another OVA as a follow-up to Stone Ocean that features Jolyne and Jotaro having a heart-to-heart talk and taking the first steps to repairing their rocky relationship. At the end of this OVA, there’s another picture sitting on Jotaro’s work desk: it’s of his daughter Jolyne, now a young lady, and of him in the background, there with his daughter, to symbolize that they’ve become a little closer to each other with the hope that they can become a family again.
And of course, the BEST ending would be an ending card of this OVA featuring a collage of pictures featuring the Kujo family and friends living and enjoying life and all this. But one particular picture comes to mind: Jotaro walks Jolyne, arm-in-arm, down the aisle during her wedding while Hermes awaits her at the altar.
