When the lighter was relit, Polpo's Stand, Shadow Sabbath, appeared and attacked. Giorno is able to see through Shadow Sabbath's weakness and faces it alongside Koichi. Koichi realizes that the arrow is involved in this situation and they realize that the point of Polpo's exam is to try to create more Stand users.
Because I observed three members of 
the Joestar bloodline back in Morioh.
لأنّني راقبتُ ثلاثة أعضاء من سلالة
جوستار في موريا
In Morioh habe ich drei Mitglieder
der Joestar-Blutlinie erleben dürfen.
Todo gracias a que vi a tres miembros
del linaje Joestar en Morioh.
Todo gracias a que vi a tres miembros
del linaje Joestar en Morioh.
J’ai vu agir
trois descendants des Joestar
...perché a Morio-cho ho potuto osservare
da vicino tre membri della famiglia Joestar.
Porque lá em Morioh, eu observei de perto
três gerações diferentes da linhagem Joestar.
Ведь в Морио мне довелось понаблюдать вблизи
за тремя наследниками Джостаров.
