Cutty tries to bully him, but he's not having it. He tells him that they need to become good assassins after all. He reminds him that his parents died when he was a child. He's brought his sword with him ever since. He explains that he has this power because experiments have shown that people like him can heal themselves quickly. He says that he doesn't know why they're on the remote rooftop. He asks if it's okay for him to show him this way. He also asks if he can enter the room by stairs. He wants to know what his other purpose is. His mother works for the mafia, and his father was a research scientist. They don't get along very well at first, but eventually they get along.
