Risotto figures out that Doppio must be a Stand user that the boss trusts in deeply because he’s able to hear the noise from a certain Stand. Risotto then uses his Stand Metallic against him. Metallic is able to control magnetic force and attacks Doppio. Doppio uses the part of the boss’s power he received from him. While they’re fighting, Risotto realizes that Doppio’s personality and actions seem to be changing and he realizes exactly who Doppio is.
It's underneath all these rocks, 
and now it's covered in sand.
إنّه تحت كلّ هذه الصّخور والآن هو
مغطّى برمال
Es ist unter all den Steinen
und von Sand bedeckt.
Terminó bajo las rocas
y cubierto de arena.
Terminó bajo las rocas
y cubierto de arena.
Il est coincé entre les rochers
et couvert de sable, en plus…
Era dietro queste rocce
e ora è tutto coperto di sabbia.
Está debaixo de todas essas rochas,
coberto de areia!
Он аж под камень закатился, 
ещё и весь в песке!
