Shingeki no Kyojin - ep12

In the aftermath of Eren going berserk it seems that something is wrong with Eren. The fact that Eren isn't in control become more apparent as Mikasa tries to bring him to his sense. That once he hits himself in the head, this results in him going silent. Then this leads to the question of what should they do now since the mission is already a failure. When it is suggest that they just cut and run, it goes without saying that Mikasa isn't pleased with the suggestion. It become clear to the commander that this would be a bad idea because he is sure that Mikasa would kill them and after seeing her skill first hand he has no doubt that she would succeeded. That is part of his motivation to not abandon Eren the other reason is that he is there greatest hope in the war against the Titans. Then because of this fact it make Eren irreplaceable, that is why they need to defend this location until Mikasa can figure a way to get Eren back to normal.

That as the elite are going about protecting Eren, we get a little insight into why Eren went berserk. That when he transformed he desired to retreat from the world and didn't possess the will to fight. That it isn't until the arrival of Armin that some progress is made toward Eren's condition. That it takes Armin stabbing Eren to get a response from Eren. Although it still isn't enough because Eren is still trapped with his dream. That he doesn't move until Armin reminds Eren of his desire to know of the world, and once he is reminded of his original reason he wanted to join the Recon squad is he able to destroy the dream. The question is was the dream create by Eren or by the Titan, anyways with Eren brought back to his sense. It seems that there is still hope that the plan will be a success it remains to be seen if there will be any further complications.
