Jotaro and the others obtain a submarine as a new means of travel. Through the Red Sea, they try to head toward Egypt where DIO awaits. Using the sonar to detect any threats on the outside, the submarine quietly dives in. They however realize that if they're attacked underwater, there is nowhere to escape, so they are on their guard. Finally, when they are about to surface, a coffee mug that was in the cabin transforms and cuts off Joseph's artificial hand.

لهذا عدت
Und deshalb bin ich zurückgekehrt.

Por eso mismo volví.
Moi aussi, c’est dans ce but
que je suis revenu.
Questo è il motivo per cui sono tornato!
Foi para isso que eu voltei.
