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.
If Rohan finds out that I've been 
using that alien to cheat...
إذا اكتشف روهان أنّني كنتُ أستخدم
...ذلك المخلوق الفضائي للغشّ
Wenn Rohan spitzbekommt, dass ich
ein Alien zum Schummeln benutze …
Si descubre que hice trampa
con el extraterrestre…
Si descubre que hice trampa
con el extraterrestre…
S’il découvre que je triche
avec l’extra-terrestre,
Se Rohan scoprisse che ho usato
quell'alieno per imbrogliare...
Se Rohan descobrir que eu estava
usando aquele alien para trapacear...
