The Antique Tray Can't Be Hidden (Part One) Conan is called to the Agasa residence and learns that Dr. Agasa is planning to make a fortune from a small vintage plate that he brought back from his uncle's villa, and he is going to ask an appraiser he knows. Conan wonders why he has been summoned, but it turns out to be Haibara. Sera had been staking out the front of the Agasa residence, and Haibara was worried. When Ran and Sonoko mention Haibara's name as a "mature child," Haibara gets angry when she hears that Sera is probably checking up on her. Then Okiya comes to bring her some food, and Sera follows her. Sera wants to hear what she has to say, but she can't leave Haibara alone, so they all head for the appraiser...
