Conny is bewildered when the Titan atop his house faintly speaks, welcoming him home, and prompting him to wonder if he just heard his mother. His group reunites with Nanaba's group, which includes Christa Lenz and Ymir. They realize that no breaches or holes occurred in the walls for the Titans to have come through. They decide to rest overnight at the Castle Utgard ruins. In Eren Jaeger's group, Eren learns that he can seal the breach in the Shiganshina District with the same crystallized skin Annie Leonhart had; it turns out the walls are literally made of the same material: Titan crystallized skin. Pastor Nick reveals that Christa is the key to all the answers. Sasha delivers Hange a scroll from Erwin, advising them to head to Castle Utgard. The Beast Titan leads Titans to attack Utgard, shocking the group as to why these Titans are active at night.
