Vento Aureo - Chapter 80 
A little while before Bucciarati's confronting of The Boss, Giorno anxiously waits in the boat for an update on the progress of his operation. As Mista and Narancia argue over the remaining chocolates the latter had been hiding, Fugo asks Giorno for a bottle of water. Suddenly, Narancia has the chocolates in his mouth while Fugo has his bottle, without remembering how he got it.
Giorno notices that something odd is happening, such as birds and people seemingly teleporting, and rushes to the church despite Abbacchio's orders. He receives a call from Bucciarati and Giorno reveals that the brooch, which fell down the elevator shaft, attached itself to The Boss. Giorno also tells him that the Boss is hiding behind the column near Bucciarati, and the lieutenant confidently cuts the column apart with his zippers to attack the Boss.
However, Bucciarati somehow sees himself behind the column, and his conscience switch to that double, seeing the Bucciarati who attacked from behind the column. The Boss's Stand King Crimson reveals itself behind a disoriented Bucciarati, explaining that Bucciarati just attacked his future self when King Crimson used his power of time erasure. In his confusion, King Crimson punches through Bucciarati's torso.
