After losing to D'Arby, Joseph and Polnareff have their souls taken. In order to have their souls returned, Jotaro shows off Star Platinum's powers before going into a match with D'Arby, warning him that cheating won't work.
I don't think we'll be able to

لا أظننا سنستطيعُ استخراج أسرار ديو منه
Wir werden ihn wohl nicht
mehr nach Dios Geheimnis befragen können.
No creo que podamos sacarle 
el secreto de Dio.
Dudo que podamos sacarle el secreto de Dio.
Vu son état, on ne pourra pas
lui soutirer le secret de Dio.
Ormai è inutile chiedergli del segreto di Dio.
Acho que não vamos conseguir 
arrancar o segredo do Dio.
