A look into Zeke's past shows his struggle to become a Warrior. His plans to end the suffering of all Eldians stems from a chance friendship made in his youth.

With the Yeagerists now in charge, Zeke's master plan is revealed. But before it is put in motion, Eren recruits help to flush out any invaders in their midst.

Caught off guard by Marley's surprise attack, Eren fends off their Titans alone. As the battle rages on above, the Scouts consider Eren's motives from the underground dungeons.

Colt pleads with Zeke to not use his scream and turn Falco into a Titan. All the while, soldiers and Titans clash in battle as Eren struggles to make contact with his brother.

The Azumabito's flying boat is guarded by a port full of Jaegerists, but the Scouts are reluctant to kill their former friends. If they wish to avoid bloodshed, they can't afford their plan to go wrong.

For the flying boat to take off, the mechanics need half a day to service it. Knowing they'll never last that long with Jaegerist reinforcements on the way, the crew is forced to change their plans.

Regardless of where it all began, Eren commits to his path of destruction during the Scouts' first visit to the Marleyan mainland, leaving Mikasa to wonder if things could've been different.
