Summary
Jolyne and Ermes discover that the two of the search party members were killed and possessed by extensions of their opponent, a plankton colony called Foo Fighters aka "F.F.", who used the victims' remains to disguise itself. F.F. explains that it is both a Stand User and a Stand after Whitesnake granted it intelligence to guard the Stand DISCs for him. Jolyne chases F.F. into the nearby barn while Ermes attempts to prevent the Stand's double from dragging away the guard to trigger their bracelets. Ermes defeats the double by drawing it out of the water and exposing it to the dried-up corpse of one of the inmates. In the barn, F.F. gains the upper hand on Jolyne after covering the ground with water, but Jolyne uses Stone Free's threads to activate the tractor and drive the discs away. F.F. chases the tractor but falls apart as its body is absorbed by the dirt. Jolyne decides to spare the dying entity when she realizes it was protecting the discs for their own sake rather than for Whitesnake's and recruits F.F. as an ally. Jolyne finds Jotaro's Stand disc, but not his memory. F.F. possesses Atroe's corpse to join Jolyne and Ermes in prison, hiding Jotaro's disc within her body. The farm is later investigated by Whitesnake and his user, Enrico Pucci, the prison's head priest.
