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.
He probably hasn't even realized 
there's been a battle here.
وعلى الأرجح لم يدرك حتّى أنّه اندلعت
معركةٌ هنا
Wahrscheinlich weiß er nicht mal
etwas von unserem Kampf.
Ni siquiera debería saber
de nuestra pelea aquí.
Ni siquiera debería saber
que hubo una pelea aquí.
Il ne sait même pas
qu’un combat a eu lieu.
È probabile che non si sia nemmeno reso conto 
dello scontro che c'è stato qui.
Ele não deve nem saber
que o Stand se envolveu numa batalha.
Да он даже не знает, 
что его стенд сражался!
