Katsuro had other stuff on his mind than Greg. Not that he would ever think about spying on him. He had run into some trouble on his rounds. One of his clients had decided to make stuff difficult for him.He and his underlings couldn't just destroy stuff and break some bones without having clarity over the situation first. And the client was not really helping them with this either. This all delayed his rounds a lot. Which in turn made his brothers very happy because they could call him and make remarks about his laziness. All together it was an aweful night and Katsuro was happy when he could finally go home for a few hours of sleep
