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 been two years since we were
مضى عامان منذ كنّا
Zwei Jahre, als man uns wie Hündchen das
Halsband umlegte und wir in Furcht zitterten.
Han pasado dos años desde que éramos
Han pasado dos años desde que éramos
que tu nous as plongés
dans la peur,
Sono passati due anni da quando fummo ridotti
Faz dois anos desde que fomos punidos,
мы тряслись в страхе, 
нас посадили на привязь как псов.
