Summary
The two mystery men, Pesci and Prosciutto, continue to search for Team Bucciarati, but are unable to find them. Prosciutto splits up with Pesci to look for them. Pesci continues to search the control room, and comes very close to finding Coco Jumbo, but is stopped when he notices that Prosciutto has activated his Stand.

Within Mr.President, the gang notices the bizarre increase in temperature. Mista asks Narancia if he wants a drink, but Narancia is unable to hear him. Narancia points out that he is feeling achy and sits down to eat a banana. Narancia starts coughing and his teeth start falling out. Narancia's entire body then starts to dry up and wrinkle, looking like an old man. Mista yells to Bucciarati, and they notice that everyone else has begun turning "old." The only ones who are unaffected are Bucciarati, Mista, and Trish. And not only them but everyone on the train has become "old."
