Episode Title:
Bystander.
Episode Description:
Two months after Historia's coronation, the military have purged remaining traces of the old regime. They also gained an abundant supply of crystals from the Reiss estate. Meanwhile, Eren perfects his Titan hardening ability and Hange develops a new guillotine weapon nicknamed the "Executioner from Hell" that allows defenders to easily kill Titans without loss of human life. Eren realizes that Training Corps commander Keith Shadis was the man who knew his father Grisha in his memories, and the Scouts visit him. Keith tells them that he met Grisha, who claimed to have suffering from amnesia, almost twenty years ago outside Wall Maria. Grisha learned about life within the walls, offered to work as a doctor, and later married Carla. During the Fall of Shiganshina, after learning about his wife's death, Grisha took Eren into the woods where Keith later found the boy alone wearing a key around his neck. Keith resigned as Commander of the Survey Corps out of the guilt of losing his men because Grisha praised him of being "special" and he believed it. After hearing his story, Eren claims he is merely the son of a special man, and the Scouts make preparations to retake Wall Maria.
