Summary
Worried that Joseph and Avdol have encountered an enemy, Jotaro and Polnareff begin looking for the two. As they do so Polnareff notices a bizarre looking man following them. The man, Alessi, tries to act casually but is unable to hide his killing intent from Polnareff. To prove that he's a Stand user, Polnareff summons his Silver Chariot, to which Alessi responds by revealing his Stand, Sethan, a shadow of disaster and chaos. The shadow reaches toward Polnareff, briefly touching him before he jumps back. Polnareff yells for Jotaro as Alessi flees from the battle. At the sound of Polnareff's cries Jotaro turns around, but is unable to find his friend. Polnareff chases after Alessi, but he is too fast and gets away. Polnareff then runs into a seemingly giant man, and after mocking him gets smacked like a child being punished. Polnareff realizes that everyone in the street has suddenly gotten larger, but when he looks into a mirror he realizes that in actuality he has become a child. Fortunately he then runs into Jotaro, but his child brain is unable to remember him. Jotaro, not recognizing his friend, walks away in search of Polnareff. Suddenly Alessi appears, ready to abuse the now weakened Polnareff.
