Summary
As everyone is being mutated by Requiem's power, Mista begins to lose his cool and blames Polnareff for putting everyone in danger. Bucciarati orders him to shut it, and the party begins to follow Requiem again, looking for a solution. Meanwhile, Diavolo notes that Chariot Requiem's shadow is always oriented opposite to the person looking at him, meaning the solution to defeat it may have a link with it. Giorno interrupts everyone and yells that they have to get away from each other. Having examined the remains of the guns, which were in fact forcibly bent despite nobody seeing King Crimson, Giorno correctly deduces that Diavolo's soul is probably possessing one of them, even unknowingly, hiding behind the soul of his host. Bucciarati asks if he has a way to detect Diavolo, and Giorno replies yes. Diavolo now realizes how dangerous Giorno will be to his plans.
