|You care for your little brother...as do I. So it is...truly a shame.|
|— Zeke Yeager apologizes to Colt Grice before using his scream|
Zeke Yeager begins to stir after falling from the top of the Wall as Eren Yeager fends off Porco Galliard's Jaw Titan. As Armin Arlert, Mikasa Ackerman, and the military try to fight off the invading Marleyans, Zeke is horrified when Colt Grice reveals that his younger brother, Falco Grice, has ingested some of Zeke's spinal fluid.
However, this does not stop Zeke from using his scream to transform Falco and all the affected members of the Eldian military into Titans. Falco's Titan attacks Reiner Braun on Zeke's orders, buying Eren time to get free. Reiner believes it would be all right to allow Falco to inherit his Armored Titan, but Galliard emerges from his Titan and sacrifices himself instead. Eren escapes from Reiner, but is then shot by a tearful Gabi Braun.
As the members of the Marleyan army continue their attack, Reiner recovers and spots Eren approaching the prone Beast Titan. Galliard lunges and halts the Attack Titan by grabbing and biting into its leg. This prompts the Attack Titan to ruthlessly beat down on the Jaw Titan, striking the nape several times and critically wounding Galliard. Eren is then shot once more by Theo Magath atop the Cart Titan, but before he can fire again, the Yeagerists come from behind and begin to strike the Cart Titan.
Noticing the Cart Titan's position, Armin and Mikasa are pinned down by gunfire from several soldiers, but Connie Springer launches a Thunder Spear and orders that they take out the Marleyan soldiers before going to the Cart Titan. Commander Dot Pixis and Nile Dok of the Military Police lead the assault while Yelena silently gazes out from above.
Inside the nape of the Beast Titan, Zeke's entire back has been destroyed from the rounds fired from the Cart Titan. He notices that he is now on the ground and begins to get to his feet. As the Armored and Attack Titans continue to fight each other, Reiner grabs Galliard in an attempt to wake him; after grabbing the area around the Jaw Titan's nape, Reiner unexpectedly transfers the memory of Marcel Galliard revealing that he tried to protect Galliard from becoming a Warrior. This raises Galliard out of his stupor, but he is overcome with emotion and unable to speak.
As Zeke is about to summon the Titans, Colt arrives with Falco, pleading to let Falco get clear from the sound radius so that he will not be affected. While stunned and remorseful that Falco consumed some of his spinal fluid, Zeke still lets out a piercing scream transforming Falco, Commander Pixis, Nile, Roeg and all the affected Eldians throughout Shiganshina District into mindless Titans. The Titans soon turn towards the numerous Marleyan soldiers and easily kill them before they can respond. Reiner notices a transformed Falco charging towards him on orders from Zeke and begins to try fighting him off.
Zeke gets shot through the head once more but Armin and Mikasa take the Cart Titan by surprise, killing the soldiers accompanying it. Noting it is impossible to fight off both Falco and Eren, Reiner notices the latter trying to escape and grabs his heel. Seeing Zeke not moving, Reiner begins to remove the armor around his nape so that Falco can bite through and receive his Armored Titan. However, Falco stops biting upon spotting an injured Galliard stumbling towards him and Reiner. After a few words on the sacrifice Marcel made, Galliard allows himself to be consumed by Falco and instead transfers the Jaw Titan to Falco. Reiner strikes Eren in blind frustration, but he is surprised to see Eren hardened his body, trapping him while he tries to escape; Reiner tries to crush Eren but is shot in the hand by a Thunder Spear, causing it to explode.
As Zeke and Eren, in his human form, try to make their way to the other, Eren notices out of the corner of his eye that a tearful Gabi has picked up the deceased Colt's rifle. Before anyone can react, she shoots a round into Eren's neck, decapitating him as a horrified Zeke cries out nearby.
