12. Night of the Battle to Retake the Wall

Complete story — includes the ending

Unable to analyse the Titan Serum because of its volatile nature, Erwin entrusts it to Levi in the event it must be used to turn someone into a Titan. Arrangements are set for the expedition to retake Wall Maria and search the Yaeger family's basement, as Erwin suspects the truth of their world lies there. Worried about Erwin's chances of survival due to the fact that he is now handicapped with one arm, Levi tries to convince him to remain behind and let Hange command, but Erwin insists. On the night before the mission, Eren, Mikasa, and Armin reflect on their hopes for a future beyond the Walls. The day of the expedition, the people of Trost gather and give the Scouts a warm send-off, surprising them, as they are generally used to being disliked. Bertholdt and Reiner stand guard on Wall Maria. In a mid-credits scene, Levi berates a shell-shocked and teary-eyed Eren and Mikasa as they stand amidst destruction. He punches Eren, causing Mikasa to attack him with her blade at his neck.
