They had to cut some parts out of this, which is really disappointing. If they're already starting the next fight next episode, then I guess they won't be put in as flash backs:
-Mikitaka explaining that the ice cream was made out of his fingers
-More bits in the making dice scene, where he explains he can't copy faces and also keeps making Bruce Lee WATAAAA noises when Josuke throws him, and also gets sick and throws up when Josuke shakes him too hard (and you can see that two of the divots are his eyes), Mikitaka asks if they're going to be taking advantage of someone while Josuke reassures him, and Josuke shuffling dice perfectly
-The scene where Rohan swaps the dice is more explicit, with him going back inside and rummaging around in the drawer before he sees them, while Josuke is still outside and trying not to laugh
-Rohan explaining the history of cee-lo and dice in general, as well as trying to intimidate Josuke by casually talking about how the Yakuza deal with cee-lo cheaters by stabbing them 21 times and shoving two of the dice in their eye sockets and the third die... somewhere else
