The two scout teams reunite after finding no breach in the wall and decide to rest in a nearby castle. But this decision doesn't go as smoothly as they hope when the beast titan arrives with a swarm of other titans to attack the castle. But after looking back on Christa and Ymir's memories, a secret is revealed that might save them long enough for backup to arrive or could cost them another loss. Meanwhile, Hange explains how Eren might be able to seal the breach in wall Maria, and they finally get some information from the wall pastor...the name of someone special hiding among their ranks.
