With the Female Titan restrained, Erwin and Levi try to figure out its identity with no success as it is able to harden its skin to prevent them from cutting out the human inside. Jean, Armin, and the rest of Levi's squad realize it was Erwin's plan to use Eren as bait to draw out the mole within the army who joined them after the Walls fell and only told his real plan to those who were part of the Recon Corps before the fall. Meanwhile, the others wonder about what is happening inside the forest until the Female Titan gives a loud scream that draws all Titans in the vicinity to her. Despite the Recon Corps' attempt to stop them, the Titans ignore the humans and eat the Female Titan's body in a frenzy, which makes Erwin call off the expedition. However, knowing that there is no confirmation that the mole has also been eaten by the Titans, Erwin orders Levi to regroup with his squad while the mole, disguised as a cloaked Recon Corps member, attacks Levi's Squad, killing Günther.
