The devil butler tells the young man that he and the third prince are going to become brothers. The young man is confused, but he swears to live and die with the prince and never to betray him. Fatty says that he feels better after becoming his brother, because he still remembers the bet he made with the girl the day before. He says that there is a saying that he must not steal the prince's wife, so he decided to become his brother. Fatty asks what the real purpose of the pearl agreement is, and he says that the founding emperor probably didn't know about it. He wonders how the spectral valley could have known about it without attracting attention. He also wonders if the royal family might have been involved in the plan, since they don't want to be seen spying on them. Fatty is worried that the prince is too smart for him, and that he's too similar to someone else.
