Summary
A transformed Pucci leaves the prison, having no use for it anymore. DIO's entire plan is revealed. Most importantly, the plan depicted that Pucci needs to head for a very precise location—North latitude 28 degrees, 24 minutes, West longitude 80 degrees, 36 minutes. Having read Jotaro's Memory Disc, Jolyne asks Emporio to help her escape Green Dolphin Street. However, Emporio says that escape is impossible due to the "true guardian of Green Dolphin Street", who can make escape impossible, even for Stand Users.

Miuccia Miuller, also known as Miu Miu, approaches Jolyne with her Stand fully revealed, warning Jolyne not to do anything stupid. Jolyne attacks Miu Miu, but suddenly finds herself in her regular cell. Jolyne is affected by Jail House Lock and cannot memorize more than three pieces of information at a time. Though she tries to reach Emporio, she is heavily handicapped by this power.

Meanwhile, Emporio is also caught and trapped in his room, unable to remember how to escape. Jolyne manages to reach the ghost room, but they are caught up by Miu Miu. When Jolyne is given a picture in binary of Miu Miu, Jolyne manages to defeat her after using her to neutralize the guards.
