Traitor (裏切り者) is the 2nd chapter of the 32nd volume and the 128th chapter overall of the Attack on Titan manga, written and illustrated by Hajime Isayama.

Overview
Theo Magath and Hange Zoë spy on the Yeagerists that have taken over the harbor when they notice plumes of steam on the horizon. Realizing that the Wall Titans have reached Marley, they regroup with the remnants of the Survey Corps and the Warrior Unit to plan their next move. As Floch Forster threatens Kiyomi Azumabito and her engineers, Armin Arlert and Connie Springer try to obtain the Azumabito family's flying boat without bloodshed.

However, their plan goes awry when Kiyomi attacks Floch and provokes the Yeagerists into retaliating. Mikasa Ackerman is forced to break into the building to defend her, revealing herself and her companions as traitors to the Yeagerist cause. Connie kills his former classmates from the Training Corps in order to secure the flying boat while Reiner Braun and Annie Leonhart transform into their Titans.

Summary
As the remnants of the Survey Corps and Warriors plan their next move, both Hange and Magath spy on the Yeagerists occupying the harbor. Hange theorizes that they are probably looking to hold on to the Azumabito, who are capable of developing airships with the engineers from Hizuru. Despite the fact they have the element of surprise, Hange admits it will be difficult in stopping the Yeagerists with how few forces they have at the moment; suddenly, they see large plumes of steam off in the distance.

Connie and Mikasa realize a strategy will be needed to keep the engineers and Azumabito from getting involved in the fighting; when Annie states that there's no way to protect the airships and the Hizuru engineers should be killed along with the Yeagerists, Pieck sides with the Survey Corp and mentions it would be a problem for all of them. As Onyankopon and Reiner discuss how they can get the airships ready for takeoff, Annie mentions that it is foolish for Jean and Mikasa to think of not harming the Yeagerists when they will have no such issues, asking Armin how they will be able to buy the time needed to get the airships ready. Annie laments how they are being thrown into this and mentions to her former friends that they do not need to take part. After recalling the words Eren said to him before the Raid on Liberio, Reiner agrees they do not need to take part.

Just then, Hange and Magath return and reveal that the steam pillars they saw were the Wall Titans and that they have already reached the northeastern part of Marley. Magath walks over to Yelena and begins choking her and breaking several joints in her arm while demanding she reveal where Eren is hiding. Hange tries to persuade him to stop, but Magath only does so after seeing Gabi watching him. He then apologizes for his behavior the previous night and admits the residents of Paradis should not be judged for the actions of their ancestors; Magath then addresses the Warriors and admits they should not be burdened by the hatred of the world. He insists that he cannot allow Eren to destroy everything in the world and begs forgiveness for what they have to do.

As Floch looks at the steam from the Wall Titans, he proclaims it is a glorious day for history. He insists that Hizuru will be wiped away and that a new nation will be born in its place. He insists that Kiyomi and the engineers contribute to this historical moment; Kiyomi mocks him by saying he is just making the world a smaller place. Floch brushes it aside and repeats that they need to know their place, placing the barrel of his gun to her temple; just then, Armin and Connie ride outside the building demanding to speak to him. Floch is perplexed as to why they are making such a ruckus. He is stunned to hear both Jean and Onyankopon have been killed and they need access to a nearby airship along with some of the engineers to chase down the Cart Titan who was heading to the south.

As Connie and Armin reach the airship, they are shocked to see two of their former Training Corps friends Daz and Samuel have joined the Yeagerists. They call Armin out on his lie and prepare to detonate the airship, but the detonator does not work. As Floch prepares to execute another one of the engineers, Kiyomi grabs his arm and a gunshot is heard; she wrestles Floch to the ground while the former screams for the engineers be killed. Mikasa breaks through a window and swiftly incapacitates several of the Yeagerists while Floch escapes; he alerts the Yeagerists outside they are under attack and to fire Thunder Spears into the building.

While Jean, Hange and Magath work with Mikasa to get the engineers away safely, Armin is shot in the face and chest by Samuel; he orders Daz, who is uncertain now what to do, to blow up the airship. As Floch orders more explosives be brought in to flush out the engineers, he fails to see Annie and Reiner navigate behind him and transform into the Female and Armored Titans. He frantically orders the Yeagerists to fight them while Yelena, Levi, Onyankopon, Gabi and Falco look from afar. Connie tackles Samuel while Armin gets up and approaches a frightened Daz. While Daz scrambles to shoot Armin, Connie quickly shoots him in the head and then shoots Samuel, lamenting they used to be friends with a shared dream.
