Response: The Struggle for Trost, Part 6

Answer is the tenth episode of the Attack on Titan anime. It is produced by Wit Studio and Production I.G. It revolves around Armin's attempts to persuade the Stationary Guard that Eren isn't an enemy of mankind.

Summary
Inside the walls, the soldiers are put on stand by. One of them, Dazz, talks to Marco Bodt that he is unable to fight anymore, as his comrades were devoured right in front of him, while he was just happy not to end up like them. However, thinking that he will be the next one to die, he takes out his sword in an attempt to end everything, but is stopped by Marco. In an attempt to calm him down, Marco points at Sasha, who, however, suddenly screams in seeming pain and asks to go to infirmary because of a stomachache.

Hearing all of this, Jean Kirschtein thinks that it is a good thing they were forbidden to speak about Eren and the rogue Titan, as it would only make things worse if the news were to spread among the soldiers. That is when they hear a cannon shot and after finding out that it comes from inside the walls, Reiner, Bertholdt and Annie rush to that place, followed by Jean.

Protected by the skeleton of Eren's partial Titan tranformation, Mikasa and Armin silently watch as the Titan attempts to move, which scares Captain Verman even more, who orders the soldiers to stand by and prepare the cannon for next shot. Inside the Titan, Eren comes to his sense and gets out, surprised to see a figure of a Titan in front of him. Wasting no time, he comes to Mikasa and Armin as the Titan starts evaporating. He tells them that the basement of his house is an answer to everything and states that from now on, he must work alone, much to Mikasa's disagreement. While they argue, Armin thinks about their situation. He then, however, remembers as Eren and Mikasa always fought to him and thinks to himself that even in the end, he acts as a coward.

However, Eren reveals the second plan, an opposite to running away. If Armin thinks he'll be able to persuade the Stationary Guard that he is mankind's ally, Eren will stay there. Armin is confused as to why they would rely on him, when Eren reveals that if it wasn't for him, they would be eaten by Titans 5 years ago. Seeing that Eren and Mikasa never thought of him as a burden, Armin decides to follow the plan, claiming that he will convince them, just as the cannon is loaded.

Armin walks out of the smoke and faces Captain Verman and the rest of the soldiers. He tries to convince them that Eren isn't an enemy of mankind. He argues that back then, all soldiers could saw Eren fighting the Titans and that the Titans viewed Eren as a prey. However, Verman refuses to believe this and orders the soldiers to be ready for an attack.

Not giving up, Armin takes a posture of a soldier's salute and one more time asks for a permission to explain Eren's strategic importance, as they may even be able to recapture the town with Eren's powers. In spite of this, Verman refuses to accept his appear and attempts to give a signal for the cannon, but is suddenly stopped by Commander Dot Pixis. Saying that he'd like to listen to what Eren and others have to say, he orders Verman to organize the reinforcements.

Pixis is then introduced as a man entrusted with complete authority over the key area of mankind's defenses. On the top of the wall, he listens to Eren and others. Saying that Eren can prove himself now, he asks him whether he will agree on using his powers to move a giant rock and block the hole in the gate. Looking behind himself, Eren witnesses the area that would be lost if the gate were to fall and ultimately agrees with the plan.
