After a long, hard journey, they are faced with a sudden goodbye of a friend. Because it's so sudden, Polnareff can't control his emotions. He starts brandishing his sword toward the unseen enemy with very little success.
Because he believed that we could defeat DIO.
لأنه مُؤمن بقدرتِنا على هزيمةِ ديو
Und das nur, weil er glaubte,
dass wir Dio bezwingen können.
Lo hizo porque creyó que 
podríamos derrotar a Dio.
Lo hizo porque creyó que 
podríamos derrotar a Dio.
Et cela parce qu’il croyait 
en nous pour vaincre Dio.
Perché era convinto fossimo in grado
di sconfiggere Dio.
Porque ele acreditava que 
podíamos derrotar Dio.
