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.
And the mystery behind the enemy's form 
is slowly becoming apparent, Boss.
واللّغز وراء أسلوب العدوّ بدأ يتجلّى
شيئاً فشيئاً يا زعيم
Und langsam wird auch klar, welches Geheimnis
hinter der Unsichtbarkeit des Feindes steckt, Boss.
Y poco a poco comienzo a dilucidar
el misterio de su camuflaje.
Y poco a poco comienzo a dilucidar
el misterio de su camuflaje.
Une partie du mystère
qui entoure notre tueur…
E in più, il mistero dietro la capacità del nemico
di nascondersi sta svanendo, Boss.
E o mistério por trás do inimigo
está cada vez mais claro, chefe.
И стал понемногу понимать, 
как Ризотто убивает своих жертв, босс!
