Summary
King Crimson having crushed the phone, Giorno runs inside the church. With King Crimson's arm inside Bucciarati's chest, Bucciarati uses Sticky Fingers' zipper to block it and turns around to attack.

King Crimson erases time again, and as Bucciarati moves away taken by his attack's momentum, the Boss explains that he can anticipate his every movement. Time appears again, and Bucciarati's attack reaches a column instead. King Crimson is already behind him, and almost split Bucciarati apart with a karate chop.

With Bucciarati fatally wounded, the Boss approaches Trish. Feeling that they are related, tries to finish her off. His attack is interrupted when he and his Stand are sucked within the brooch in which Giorno had planted some of Coco Jumbo's cells to reproduce its power. Despite his state, Bucciarati is still determined to get Trish out of here.
