The Secret of Guard Westwood (1) (看守ウエストウッドの秘密 その① Kanshu Uesutouddo no Himitsu Sono 1), originally Fight Club (ファイトクラブ Faito Kurabu) in the WSJ release, is the six hundred fifty-fourth chapter of the JoJo's Bizarre Adventure manga. It is also the sixtieth chapter of Stone Ocean.
Jolyne is seen in her dark cell. One of the guards shines a flood light into it, nearly blinding her, and she ducks under her bed like an insect. Afterwards, it's revealed that the guards were betting on this beforehand, but the guards argue since the loser didn't have enough money for the bet. Jolyne stands up, much to the guards' anger, and is sprayed down.
The guard that is holding the hose gets some on the other one and they start pushing and shoving. The two guards start to fight, with Jolyne looking on, puzzled. After the fight is over, the winning guard, Viviano Westwood makes a challenge to all in the punishment ward. Meanwhile, Pucci realizes that Maxx is gone, and plots how Jolyne will be killed by the four Stand users in the ward before she gets to DIO's Bone.
