Midnight Sun.Eren finds himself alone with Armin's burnt body and the unconscious Bertholdt. His reverie is interrupted by the Cart Titan carrying Zeke, who asserts that Eren was lied to by his father. Zeke departs when Levi arrives, still in pursuit, promising to return and save Eren. Elsewhere, after Reiner hands her a letter from Ymir, Hange was about to kill him before convinced by Jean to have Mikasa fetch the Titan serum from Levi so they can transfer the Armored Titan power to one of their own. But as the Cart Titan rescues Reiner, Mikasa learns from Eren that Armin is still alive as Levi prepares to inject him with the serum. But Floch Forster, the only surviving recruit from the suicide charge, arrives with the mortally wounded Erwin. This causes Levi to consider Erwin instead, causing Eren and Mikasa to openly defy that decision with the latter attacking Levi until being restrained by Hange. Once everyone calms down, Levi orders everyone to leave and prepares to inject Erwin. But Erwin withdraws his arm in delirium, causing Levi to recall his conversation with Erwin before the suicide charge and ultimately chooses to let the commander rest in peace and give the serum to Armin instead. As Erwin succumbs, Armin becomes a mindless Titan and eats Bertholdt. Levi and Hange mourn the deceased Erwin while the rest of the squad share an emotional moment as Armin emerges healed from his Titan form.
