Attack on Titan Episode List


Armin and the others notice the Titans are climbing the trees, unable to get high enough to be of any danger to them, while wondering about the cannon shots they heard deep in the forest. Meanwhile, Eren points out that the commander does not trust them if he hasn't told them about their true plans. Petra and the others try to convince Eren to trust Levi and Erwin's decisions. Deep in the forest, Commander Erwin notices Levi and Mike cannot cut through the Female Titan's wrists when the Female Titan hardened only its hands that protect its nape. While Levi talks to the Female Titan about cutting off its limbs, the Female Titan screams out loud. Mike reports that Titans are rushing towards the Female Titan in the woods after sensing their smell.

Sasha tells Mikasa not to go because the screams of a captured animal means danger. Erwin orders his men to protect the Female Titan from being eaten by the other Titans. When things do not go well, Erwin has his men retreat. Mikasa's group see the black smoke rising from the forest. Eren's group starts leaving the forest. Then, Gunther notices a smoke signal nearby and tells his group to head towards Levi. He realizes that person isn't Levi. Then, it's too late. The hooded soldier cuts through Gunther, killing him.

The following quotes are from the Crunchyroll subtitle script, timestamps are approximate.

Armin: "The lives of a hundred fellow soldiers... Or the lives of all the humans within the walls... The Commander made his choice. He chose to let those hundred die. I haven't lived that long, but I'm certain of one thing. If there's anyone who can bring change, it will be someone willing to sacrifice what they care for. It will be someone who can throw aside their humanity, in order to defeat monsters. Someone who can't sacrifice anything can't ever change anything!"

— Armin describing those who sacrifice can change things
