The doctor is shocked to see that the monster is gone. He thinks it's because he killed the monster, not because there are more monsters out there. He tells the doctor that he has two options: he can go back to town to ask for backup, or he can stay behind and help the police solve the case. The doctor thinks that's a good idea, since he's an ordinary citizen. But the doctor still remembers when he first met the doctor, when he thought that the doctor was a pervert, and that he was also willing to risk his own life for the sake of justice. He says that the poison marks on the driver and the tracks on the car are the same ones he found on the brothers back then. He's sure that they're the same people who killed his brother, and he wants to go in and find out what's going on. The police officer and his assistant show up, and the doctor is all, "Who are you? I'm an officer from the police department! This is my assistant." The doctor asks who they are, and they say they are his "unexpected guests." He orders them to cooperate with the police so that they can have a "lighter sentence." He says he'll cut their tongue and "ferment it into wine" .
