The interior of the city is in chaos, just as it was five years ago when the Colossus Titan destroyed the gate of the southern district. Titan's have temporarily occupied the southern gate, but the gate has been sealed. The narrator is horrified by this news, and he is kept chained in a dungeon below the city walls. The survey corps has come up with a plan to use the power of the titan to retake the city. The commander of the corps, named Erwin Smith, tells the narrator that the plan is a bad idea because it will only further ruin the human race. He says that he knows why the people want to take on the side of eren: when he and his friend stabbed three adults to death when they were 9 years old, it was clear that they were human beings. Erwin says that if they want to kill eren, it is not a problem, because he would pair him with Captain Levi as a "failsafe" .
