Summary
Jolyne watches a movie scene over and over, annoying the other inmates. She tries to read a comic, but fails to understand why it's funny. Jolyne notices the movie again and spoils the ending, to the inmates' dismay. She remembers her goal and sees Miuccia staring at her left hand. She sees the note on her hand reminding her to punch anybody who stares at it, and attacks Miuccia. Miuccia runs, and Jolyne gives chase, noticing Miuccia's Stand, labeling her as an enemy. She forgets what she's doing again, and is suddenly surrounded by guards who are prepared to shoot. Jolyne turns herself into string and latches on to a guard's back to hide herself. Miuccia reveals that she tricked Jolyne into leading her to Emporio's room.
