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 always do the opposite 
of what I think you'll do.
تفعلُ دوماً عكسَ ما أعتقد أنّك ستفعل
Du machst immer das Gegenteil
von dem, was ich von dir erwarte.
Nunca haces lo que creo que harás.
Nunca haces lo que creo que harás.
Tu fais toujours l’inverse
de ce à quoi je m’attends,
Fai sempre il contrario
di quel che penso che farai.
Você sempre faz o contrário
do que eu acho que você vai fazer...
