Summary
Giorno heals Bruno's body and peeks into the columbarium through the hole, seeing the bloodbath it was. Turning his gaze back on Bruno, Giorno realizes that Bruno is apparently dead and panicks. Hung on the roof of the columbarium, the Boss sees how dangerous Giorno can be and opts to kill him, but before he can reveal himself, Giorno hears Bruno's ghost telling him to leave the church. Giorno turns his head, but sees nothing. However, Bruno finally wakes up to tells Giorno to call the others before King Crimson can attack. Giorno sends his laptop as a flying fish crashing near the squad and they rush toward Giorno. As they get out of the church, the Boss chooses to retreat temporarily, not willing to show himself before so many people, but swears to get them.

Bruno reveals to his team that he betrayed the Boss for Trish's sake, shocking everyone. He temporarily collapses, just long enough to impale his hand into a metal shard without reaction, to Giorno's confusion when he sees it.
