Basically during the Shiganshina battle, Kenjaku revealed there was one more sibling which made Choso and Yuji freeze and listen, he revealed that they had a younger (brother/sister) who lived somewhere in tokyo, when the battle was done he went through the while city trying to find you and when he did he broke into tears, right now he was sitting in the corner of the room just hugging you close while crying (He's crying because he's worried you were hurt by Kenjaku) while Yuji and Namo just looked confused
