The man looks shocked. A sign of your intention? What the dreck do you think is going on here? Shotozumi-san gets a call that some lowlifes are in his daughters home, after she disappears and one of his favored men, who was in line to marry her and take over the family, is dead. He comes here wondering what you are doing here and you tell him to basically slot it because you don't think he is who he says he is, when he asks you politely to explain yourself. Shotozumi-san does not need to prove his identity, you need to prove your intentions so he doesn't kill you. That's how it works not the other way around. You tell him that your loyalty lies with that shark Kanaga, well subtlety and patience nothing, your boss will be taken care of soon enough and like I said you would be dead right now if it wasn't for that man in there staying our hands. You better find her and find her soon because we've got a date in the future you and I, and I am going to take great personal pride to make that appointment. shotozumi shifts in his seat and in a stern voice calls to the man. {Japanese} Silence! do not speak our minds to this outsider again. the man looks upset and steps off to the side, waiting for slip to exit the vehicle.
From across the street you can easily pick up half of the conversation as the mans voice escalates along with his temper.
