Stone Ocean - Chapter 75
Having no memories whatsoever, not even the basics of human etiquette, Jotaro sits without consciousness in a lotus position. The Speedwagon Foundation watches over him, slowly teaching him things like how to shower and the English language. While his bodily health is maintained, without memories of himself, he has no goals or objectives; with no will to live, Jotaro's muscles are slowly deteriorating. One of the doctors tries to touch his head, and Star Platinum instinctively swings Jotaro's arm in the doctor's direction. He smashes his IV and sustains some wounds on his arm, the cuts forming the word, "Jolyne".
In Green Dolphin Street Prison, Jolyne remembers a time when she was younger. She had found a wallet on the ground of a parking lot. Nearby, a kid was explaining to his dad that he had lost the wallet. Upon seeing Jolyne with it, he assumes she stole it and calls the police. Jolyne tries to explain that she is innocent, but the man doesn't listen and she is apprehended by the police. At the police station, Jolyne's mom talks with the police about letting Jolyne go. Jolyne thinks she sees her father approach her, but it is just a man dressed like him. As she and her mom leave the station, they pass by a psychiatrist talking to other parents. He states that daughters who have bad relations with their fathers are more likely to get into crime and bad situations.
Back in the present, F.F. heals Jolyne's wounds. However, a certain wound on her arm, one in the shape of her name, will not heal. After going to prison, Jolyne had learned that her father really did care for her. She realizes he had only stayed distant from her to protect her and her mother. She understands that all Jotaro wants is to protect his family.
