After being pierced with the arrow, Silver Chariot becomes Chariot Requiem and goes berserk. As a result, everyone’s minds are switched. Among all the confusion, Polnareff reveals himself to Giorno and the others. If someone with power uses the arrow, they would be able to obtain the power to rule over the minds of all living creatures. Polnareff lets them know that there is more to their Stand’s usual Stand ability if they have access to the arrow. Giorno and crew reunite with Bucciarati and they all go to try to steal the arrow back from Chariot Requiem.
This can't be possible unless 
there are two Diavolos!
لا يمكن أن يحدث هذا ما لم يكن هناك
!اثنين من ديافولو
Das wäre nur möglich,
wenn es zwei Diavolos gäbe!
¡Tal cosa solo podría ser posible
con dos Diavolos!
¡Tal cosa solo podría ser posible
con dos Diavolos!
À moins qu’il y ait deux Diavolo,
ça ne peut pas être po…
Non si spiega, a meno che
non esistano due Diavolo!
Isso só é possível
se existirem dois Diavolos!
Такое могло бы случиться, 
только будь Дьяволо двое!
