In order to defeat Chili Pepper, who intends on killing Joseph Joestar, Josuke and the others head to the harbor. Jotaro believes that Chili Pepper will try to get to Joseph's boat with something that requires a battery, so he leaves Josuke and Koichi at the harbor, telling them to attack the user if he shows himself. As Josuke is dealing with his conflicting feelings towards Joseph, the very confident user of Chili Pepper shows himself.
I can't really see him as my parent.
لا أشعر بأنّه أبّ أو ما شابه
Er ist für mich nicht
wie ein Vater.
No se siente como un padre ni nada.
No siento que sea mi 
padre ni nada de eso.
Je ne ressens rien pour lui
en tant que fils.
Non esiste alcun legame tra noi.
Não sinto como se ele
fosse mesmo meu pai.
