Reiner and Porco continue to fight Eren while Pieck fires projectiles from above. Eren severely injures Porco. Colt pleads with Zeke not to use his scream until Falco is out of range, but Zeke screams anyway, turning everyone who drank his tainted wine into Pure Titans, including Pixis, Nile, and Falco.
Colt is incinerated by Falco's transformation. Zeke orders Falco to eat Reiner, but Falco instead devours Porco who offers himself to be eaten. He still believes he is a better man than Reiner.
The Survey Corps attack Pieck and Reiner with Thunder Spears, clearing a path for Eren to exit the Titan body and reach Zeke in his human form. However, Gabi uses Colt's anti-Titan rifle to decapitate Eren. His head falls into Zeke's hand.
Eren's consciousness is transported to the Paths dimension, where he meets an aged Zeke in chains. A young girl, who is the soul of the Founder Ymir approaches. Eren declares he never meant to follow Zeke's plan and attempts to control her.
Zeke reveals that Ymir only follows the orders of those with royal blood. He sheds his chains, and in another attempt to convince Eren to follow his euthanasia plan, he touches their heads together.
