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 have to keep the cheat going to 
the end and break through this!
يجبُ عليّ الاستمرار في الغشّ حتّى النّهاية
‏وأتخطّى هذا الأمر
Ich muss bis zum Ende schummeln
und das überstehen!
¡Saldré de esta haciendo
trampa hasta el final!
¡Saldré de esta haciendo
trampas hasta el final!
Dovrò continuare a imbrogliare
e arrivare fino alla fine di questa sfida!
Tenho que trapacear até o final e sair vitorioso!
