Rohan has a feeling that Josuke is cheating at cee-lo, and cuts off his own pinky. If he is unable to figure out Josuke's trick in the next round, he says he will pay him 2 million yen to have him use Shining Diamond to fix his finger. But if Rohan does figure it out, he says he'll take Josuke's pinky instead. He even calls Tamami to act as a mediator, having him use his Stand ability so Josuke can't play fairly the next round, either.
I called him earlier and asked 
him to act as an official.
استدعيتُه إلى هنا قبل قليل وطلبتُ منه أن يعمل كحكم
Ich habe ihn angerufen, damit er
die Einhaltung der Wette kontrolliert.
Lo llamé para que hiciera
de intermediario.

Je l’ai appelé car il travaille
comme percepteur de dettes.
L'ho chiamato io per chiedergli
di venirci a fare da garante.
Eu o chamei aqui para ele
atuar como mediador.
