|Next time we come here... we'll be able to bring Annie, Krista, and that back to our hometown. And that... will be the last time we ever come here.|
|— Reiner reminds Bertolt of their duties|
Eren, Ymir, Reiner and Bertolt are still within the Titan Forest. Ymir has fully regenerated and Eren, semi healed, starts questioning her about what they can do in order to escape and get information. Meanwhile, Bertolt is not sure about trusting Ymir, but Reiner believes in her. They are talking about going back to their Hometown and revealing Bertolt's feelings towards Annie when they see signal flares, meaning that the Survey Corps are coming after them. They restrain Eren and Ymir and escape with the vertical maneuvering equipment but Ymir stops them, saying that she knows that Historia is coming and this is the time to bring her with them, as a proof of faith on her. Reiner finally accepts and Ymir transforms into her Titan form. When she spots Historia, she swallows her and runs away. She lands on Reiner's back as he had transformed into a Titan and is running away, while Hannes vows to bring Eren back.
Ymir's limbs finish regenerating while Eren is dissatisfied about being unable to get a good amount of information out of Reiner and Bertolt. Bertolt asks Reiner if he really trusts Ymir, because her Titan form was small but fast and could outwit them easily. Bertolt also reminds him that she was the one who devoured Marcel, their childhood friend. Reiner reasons that because she became human again and that she cares a lot about Historia, they can trust her. Bertolt doubts whether Reiner was normal or not, and Reiner asks him to relax as he was still a "warrior". Reiner reminds him that Annie had tailed some Wallist members and figured out that Historia was from one of the noble families connected to the Church of the Walls. Thus, it would be easier to locate the "Coordinate" they are looking for if Historia was with them. Bertolt wishes to finish their mission after bringing back Annie, Historia, and the "Coordinate" and returning to their Hometown. Reiner wants Bertolt to express his feelings to Annie.
Reiner notices signal flares from a distance and Bertolt exclaims that the Survey Corps should not have been able to assemble their enemy detection formation without transporting a large number of Horses over the Wall. Reiner speculates that Commander Erwin may be present and jumps off towards Eren to subdue him. Eren tries to fight back but to no avail. Bertolt asks Ymir if she remembers eating people in her Titan form. Ymir replies that she became human five years ago and does not remember eating anybody. Ymir observes that Eren does not remember anything either, and she wonders if Bertolt hated her. Bertolt asks her how long she was roaming outside the Walls to which Ymir replies that she had spent about sixty years in her Titan form, which was like a never ending nightmare.
Reiner and Bertolt carry Eren and Ymir respectively on their backs and set out to leave. Ymir wonders why they did not wait until night, and notices signal flares behind her. Ymir notes that Historia was pursuing her and expresses her desire to take her with them, to which Reiner and Bertolt turn a deaf ear. She grips Bertolt and blocks his eye so that he has problems maneuvering. Ymir threatens them to fight each other to death if they do not get Historia.
The Survey Corps approaches the forest until they notice a flash of light inside it. Erwin assumes it to be from the Titan transformation. Hannes and the others switch to the vertical equipment and enter the forest to retrieve Eren. They hear a Titan's cry and subsequently see Ymir's Titan form clinging to a tree, waiting for them. Connie and Jean try to talk to her, but she does not respond. Ymir surveys each of them one by one until she notices Historia, captures her in her mouth and escapes with great agility. Reiner transforms into his Titan form and Bertolt and Ymir cling to his back as they make their escape. Hannes and the others switch to riding horses and Hannes states that he would bring Eren back even if it cost him his life.
