SO Chapter 84

F.F. - The Witness, Part 2 (・-目撃者 その②), originally in the WSJ release, is the eighty-fourth chapter of Stone Ocean and the six hundred seventy-eighth chapter of the JoJo's Bizarre Adventure manga.

Summary
F.F. muses over what to do, weighing the importance between getting caught by Father Pucci and killing D an G. As she decides that killing D an G is the most important thing to do, Pucci is seen counting prime numbers on his fingers. F.F. gathers that Jolyne is still alive, based on D an G's shoulder wound.

Meanwhile, Pucci exclaims that he wishes to get all the details of what happened from D an G excitedly. He finds and speaks to Guccio's corpse, inserting a CD disc into his head to make him play a symphony (specifically, the Hallelujah chorus from Handel's Messiah) in celebration.

The guards decide to leave D an G's questioning until later and to start a thorough search of the building to find the other prisoners; Pucci declares that the interrogation will begin now, not later. He then notices a gun phasing into one of the guard's hands when he goes after the ambulance, realizing that this guard is actually F.F. She holds her gun at D an G, and Pucci panics, as he won't be able to ask for details if D an G is dead. F.F. attempts to shoot D an G, but a guard with a DISC implanted in his head suddenly grabs her wrist and makes her miss. As F.F. realizes in a flash that Pucci is Whitesnake, the priest asks her whether himself or D an G will be her first target.
