Complete story — includes the ending
Mikasa tries to reason with Eren's Titan form, but to no avail. He accidentally incapacitates himself, slumping to the ground. The elite squad protecting him sends up a red flare to signal that the plan has failed, to the dismay of the rest of the troops. As Armin heads toward Eren to investigate, the elite squad argues about withdrawing and abandoning him to the Titans but Captain Ian convinces them to protect him even while he is incapacitated, recognizing Eren's potential as a valuable asset. Jean's mobility gear malfunctions, forcing him to hide from Titans. Armin reaches the unconscious Eren and plunges his sword into the Titan's left arm, which briefly awakens Eren from the pain. As Armin speaks to him of their dream to see the outside world and his promise to kill all Titans, Eren leaves his dreamlike state and regains control.
