Mista and Giorno were able to defeat Ghiaccio. They then confirm the mission on the disc and head to the location they're supposed to take Trish. Bucciarati goes up the tower with Trish, but while they're in the elevator, Trish suddenly disappears. Bucciarati then realizes what the boss's true motives are.
Or did you overestimate your 
own powers and get cocky,
،أم أنّك بالغتَ في تقييمِ قواك واغتررت
Oder überschätzt du nur
deine Kräfte und bildest dir ein,
¿O solo luces tus poderes por vanidad
¿O solo luces tus poderes por vanidad
À moins que tu te sois surestimé
O hai sopravvalutato i tuoi poteri
e hai finito per peccare di arroganza,
Ou está tão confiante em
seus próprios poderes
