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.
Apparently if I go faster than 
60km/h, it can't keep up.
يبدو أنّني إذا أسرعتُ أكثر من 60 كم في السّاعة‏‏
‏لا يستطيع مُجاراتي
Scheinbar kann es mit einer Geschwindigkeit
von über 60 km/h nicht mithalten.
Parece que no puede alcanzarme
si voy a más de 60 km/h.

A quanto pare non riesce a starmi dietro
se supero i 60 chilometri all'ora.
Aparentemente elas não passam dos 60 km/h...
