Forest of Giant Trees: The 57th Exterior Scouting Mission, Part 2

The Forest of Giant Trees is the eighteenth episode of the Attack on Titan anime. It is produced by Wit Studio and Production I.G. It continues the story as the Female Titan continues smashing through soldiers in order to find Eren, eventually reaching him in Forest of Giant Trees.

Summary
After the Female Titan leaves for Eren, Reiner asks Armin about his Three Dimensional Maneuver Gear while tending his wounds. Armin replies that it seems to be working properly. Reiner then notes that they have only one horse, with Jean attempting to call his own. He thinks to himself about what they will do, knowing that someone will have to be left behind. Meanwhile, Armin seems to be spacing out, remembering his encounter with the Female Titan. Reiner then also says that they have to decide the one who will stay behind. Jean fires an emergency signal as a last hope and Armin proposes himself to be the one left behind and as is about to ask Reiner to deliver a message to Irvin, when Jean notices someone approaching.

They see Christa running towards them, leading two spare horses. With one of them being Jean's horse, Reiner notes that Christa is a really nice person, unable to believe that the emergency signal actually worked. Christa just says that she's glad they all are alive as the three boys stare in awe, with Reiner even stating to himself that he wants to marry her. Afterwards, they head back to the formation, thinking that a retreat signal should be given soon, but are surprised to find out that the mission continues with different course. They question this decision, but follow the order and fire the green signal as well.

Elsewhere, Levi and the rest see this too, with Auruo being the one to shoot the signal. Just as Eren thinks to himself that the operation seems to be going well, a soldier approaches them with a message that right side of the formation is destroyed. Levi orders Petra to deliver this message further to the formation, with Eren wondering if Armin and the rest are okay. At that moment, a signal of an Abnormal approaching appears.

At that location, four soldiers engage in combat with the Female Titans. One of them shoots a black smoke signal towards it, stopping it in its running and orders the rest of the soldiers to attack, thinking that their target cannot dodge three simultaneous strikes. However, the Female Titan jumps and smashes two soldiers, with the third one being killed by the Female Titan spinning him on his wire. The remaining soldiers tries to escape in order to let everyone know about this Titan, but it catches up with him and kills him as well. Two more soldiers notice this and head there in an attempt to stop it, just to lead into more casualties.

Meanwhile, the formation keeps heading east, contrary to the original plan. They eventually reach Forest of Giant Trees. As Irvin goes to the forest, he orders that only the center of the formation should enter it. Sasha questions their course, but is told that they're going around the forest. Elsewhere, Jean also wonders about the plan as it's completely changed compared to their original mission. A senior soldier then orders them to stop and get rid of any Titans that attempt to enter the forest. At that time, Connie also asks about what happened to the formation, with Mikasa replying that they're most likely avoiding the forest this way, losing their recon ability in process.

Waiting above the trees, Jean complains about the orders yet again. When Armin asks him about his intentions, he replies that he's going to follow the orders, that being the right decision. As they see a Titan approaching, Armin wonders about Irvin's hidden motive. Inside the forest, Eren asks Levi about as to why they'd enter the forest alone and lose their ability to protect themselves. Levi replies that he should think if he doesn't want to die, noting the trees to be the perfect enviroment for Three Dimensional Maneuver Gear. Eren figures out that he won't get every answer on a silver plate, thinking that others learnt to fight this way as well, but he then notices that the others have no idea about what's going on either.

While Armin deduces that Irvin intends to deal with the Female Titan inside the forest, a horrified Jean watch all the Titans attempting to each them, noting that they don't need to fight as long as they don't try to enter the forest. Suddenly, a black smoke signal is shot right behind Eren's group, signalizing the arrival of an Abnormal. Erd deduces that it's the one that has been crushing the soldiers at the right side. Levi orders everyone to draw their blades just as they watch the Female Titan appear and crush the soldier behind them, beginning the chase, with the Female Titan seemingly excited as it finally finds Eren.

As they are being chased, Petra asks for a permission to use their 3D Maneuver Gear, but Levi just silently watches as reinforcements arrive to engage in fight with the Female Titan. However, they get easily killed, much to Eren's horror. Petra asks Levi for orders yet again, while Auruo suggests taking the Titan down. Erd takes out his blade, determined to kill it. Eren smirks, thinking that the Female Titan has chosen hell for chasing these masters at Titan killing, but is then surprised to see that Levi is still being silent. Finally, Levi tells them to cover their ears, takes out his gun used for signals and shoots.
