REACTION – The second episode starts off with Eren, Mikasa, Armin, and the rest of the soldiers behind the walls as they set out to help out the Survey Corps near Wall Rose. They bring along with them, Minister Nick, a priest of the Order of the Wall under the goal that he’ll speak up once he gets to see the real action beyond the walls.
Armin thinks that a titan’s body has the ability to harden itself – his way of making sense in regards to the titans in the wall. He supports this by bringing up Annie and her crystallization.

Eren and Mikasa remain the same.
Eren is still does things without thinking and Mikasa is still clingy to Eren.
Throughout the episode, we focus on Sasha as she travels to warn her village of the wall’s breach. As she arrives in the abandoned village, she encounters a small titan munching on an old woman whilst her daughter watches the whole thing unfold. Pretty devastating for the young girl and our hero, Sasha, rushes her the hell outta’ there.

It shows a very emotional side of Sasha as she remembers about her old roots in the forest – how she never gave two sh*ts about the world, as well as her confrontation with Ymir about “being too polite and ashamed of her dialect.”
The whole ordeal gave Sasha a sense of duty – that the world doesn’t revolve around her and she has to give a damn as well. That showed as she was fighting off a titan to save this young girl.

It showed a whole new and deeper side to the “potato girl” we once deemed as.
At the last part of the episode, we get to see Connie and his desperation to know whether his village was alright or not – since the titans attacked from the village’s location.

As he arrives at his house, there is a titan on it, unable to walk but alive. End episode.
This episode provided some great screen time for Sasha’s character. I can relate much more to her now after watching this episode – not just a funny, comic-relief character but someone who has grown in her time as a soldier fighting titans.
Overall, great episode. Quite an improvement from the first. Honestly, they should’ve debut the first episode with this instead of the heavy recap.
