Attack on Titan, Vol. 16

With the king deposed and the aristocrates arrested, the Survey Corps has managed to avoid destruction, just barely. But Eren, being held in a secret underground cavern, is in grave danger. His captor Rod Reiss has alluded to the sins of Eren's father, and seems to know more about how the world behind the walls works then anyone else... but will Levi and Mikasa arrive before Eren is executed, or worse?
