Luckily for the pair, there was no one in the park at the moment besides them and a fist fight would surely attract attention and possibly get policemen on their case. Of course both men wouldn't want that as Gregorio let out a short breath as Katsuro had kicked his knee, "Shut up!" he shouted as he was sure in his state of mind that Katsuro just loved toying with him as his eyebrows furrowed at Katsuro's joke, of course reading that as a taunt. Gregorio ended up giving Katsuro a right hook to the man's gut this time, if anything Gregorio was probably acting like a thug rather than a higher up, even if he was the Big Boss' kid. Was it that obvious that his father never acknowledged him as a son? Of course, him being paranoid about the other man possibly knowing about his family life was also a factor he was ostrichsized from the family but for now he wasn't thinking about that as he'd probably beat at Katsuro some more.
