The Secret of Guard Westwood (story arc)

The Secret of Guard Westwood (看守ウエストウッドの秘密) is the twelfth story arc in Stone Ocean.

It narrates Jolyne's predicament in the punishment ward of Green Dolphin Street Prison, where the prison guard Viviano Westwood goes berserk alongside the rest of the prisoners inside.

Summary
Due to the many unexplained injuries and deaths occurring around her, Jolyne is sent to the Ultra Security House Unit within the prison. Meanwhile, Emporio reads Sports Maxx's memories: in the prison's chapel, Whitesnake presented a bone to Sports Maxx and asked him to revive it with his Stand. Though Maxx successfully revives the bone, the resulting invisible zombie escapes toward the Ultra Security House Unit. Whitesnake lets the bone escape, wanting to observe its effects. The memory disc then ejects from Emporio.

F.F. tells Emporio that Jolyne has already seen the disc, implying she purposely got sent to the punishment ward in order to find the bone. Realizing that Whitesnake will attack her while she's separated from her allies, F.F. asks Emporio to help save her. Emporio replies that it's impossible: even if Weather Report wasn't in the infirmary, he has no way of infiltrating the ward. However, despite Emporio's warnings, F.F. convinces the room's remaining occupant, Narciso Anasui, to assist her, despite his murderous past.

In the punishment ward, the prison guards Viviano Westwood and Sonny Likir arrive to hose the prisoners as it is showering time. Suddenly, the two become frenzied and start fighting; Westwood wins by knocking Likir out. Meanwhile, Pucci declares that he had sent four Stand users to go after Jolyne, while Westwood releases all of the prisoners in the ward.

In a flashback, Pucci asks DIO what he thinks is the "weakest stand", to which he responds by explaining the Stand Survivor, whose only ability is making people want to fight each other. The flashback ends as Pucci asks if he can have the Stand, knowing it could be useful some day.

As Anasui and F.F., who had called the man for assistance earlier, breach the security checkpoints, Jolyne begins to fight Westwood. Westwood is a tough fighter and wields Planet Waves which manipulates small meteors. The fights turns very brutal until Jolyne sees a little prisoner taking DIO's Bone. Knowing that this was what Whitesnake had been searching for, she ends the brawl by managing to bypass Westwood's invulnerability to his own meteors by using them to propel a boot toward his face, defeating the guard.

Jolyne shifts her focus into finding the prisoner who had taken DIO's Bone when she notices all the other prisoners in the ward have been defeated, but their bodies are mysteriously bloated. She then sees two people, a short old man with a taller man, and deduces that they may be Stand users.
