Stone Ocean - Chapter 33
Jolyne retrieves her father's Stand Disc and inserts it into her forehead. After possessing Star Platinum for an instant, the disc ejects itself because the stand is too powerful for Jolyne to wield. She becomes ecstatic now that she can save her father, but Ermes reminds her that they need the Memory Disc as well.
As they look through the other discs, Atroe appears behind them. This startles them, but Foo Fighters reveals that she has possessed and repaired Atroe's corpse so that she can walk on land. F.F. decides to protect Jolyne, and will impersonate Atroe to stay near her. Getting thirsty, F.F. begins drinking water off the floor.
Jolyne asks F.F. about Whitesnake, but F.F. claims to know very little; Whitesnake rarely comes to the barn, and the discs in the tractor are only the Stand Discs he doesn't need. No matter how strong a Stand is, they only work if their user has the right potential. This makes Star Platinum's disc nearly worthless, as few have the potential to wield it. In actuality, Whitesnake only wanted Jotaro's Memory Disc. Responding to the earlier call, the guards arrive at the farm. F.F. hides Jotaro's disc in her overalls as the guards take the three, as well as the injured guard, back to the prison.
Later in the barn, Whitesnake ponders about Jolyne. She was just bait to be used to lure in Jotaro, but Whitesnake has become concerned of her abilities. He deduces that she must have received help in order to defeat Foo Fighters, and suspects Ermes and Atroe. The guards tell the priest, Whitesnake's user, that it is getting dark, and that they should be heading back to the prison.
