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.
You want to get back at me by 
telling me a stupid lie like that?
هل تريد أن تردّ الاعتبار بكذبة غبيّة كهذه؟
Willst du es mir heimzahlen, indem du
mir so eine saudumme Lüge auftischst?
¿Piensas desquitarte
inventando mentiras?
¿Piensas desquitarte
inventando mentiras?
Tu veux te venger
en me faisant avaler des bobards ?
Vuoi vendicarti di me
inventandoti una storiella così stupida?
Está tentando se vingar de mim
com essa mentira ridícula?
