SNK Chapter 85 - So what’s going on?
They’re all living in the Truman Show.
Or the Matrix. Or Plato’s Cave.
Everyone in the story has been thoroughly, thoroughly duped. Hell, even outside the story - we as readers were just as duped. Because the story that we have been following so far has just been revealed to have been not only fictional in our world, but also in their world.
In the SNK anime there’s a brilliant scene in Episode 11 where Pixis is talking with Eren on Wall Rose. He mentions that prior to the Titans’ domination of the earth, humans were endlessly fighting each other over their differences. “Then someone said, if there was an enemy that was not part of humanity, that we would all unite and humanity would stop fighting each other.” Both Eren and Pixis dismiss the idea as naive and overly optimistic - as the series has repeatedly proven, especially in the Uprising Arc, that the idea of “humanity uniting best against a common enemy” is deeply flawed.
But this “someone” definitely thought it was plausible. And, as Isayama told the anime team the entirety of the story’s plotline, I believe that this scene was included to hint towards the reason behind the First King’s obsessive containment of humanity.
We always thought that the Walls were created to keep the Titans out. We were wrong. They were created to keep the humans in. They were created for humanity’s own safety, but not from the Titans, from themselves.
So, my hypothesis is more or less this:
Titanshifting is a widespread science for humanity outside the walls, serving primarily military purposes. But although Grisha calls this world “harmonious” now (and he may just mean that they aren’t under threat from the Titans), in the past they were constantly warring among themselves - as is perhaps represented by this tableau in the anime’s second ending sequence:
The First King was horrified by the civil wars tearing his people apart, and decided that humanity was a dog that needed to be put to heel to save it from eventually destroying itself. For this reason, he obtained the Co-Ordinate, ordered his armies to titanshift, and then commanded hundreds of Titans to harden themselves in three, widespread concentric circles which were to becomes Walls Sina, Rose and Maria - encapsulating his nation, and all its inhabitants, within. He then gave the command to the remaining Titans outside of the Walls to devour humans on sight. Finally, he ordered the destruction of all records of human history within the Walls, used his Reiss Titan powers to wipe the memories of everyone within, and spread misinformation claiming the extinction of humanity at the hands of the Titans.
In this way, the First King enacted his grand masquerade. He set up the circumstances that would supposedly force humanity to perpetually unite itself against a common foe, and therefore create a utopia. We have seen time and time again that he is wrong - that there is gross inequality within the Walls, that there are orphans who have to beat people to death to survive, that change for the better is suppressed at every turn - but in the First King’s paranoid, control obsessed mind, that is still preferable to the chaos that would ensue if his subjects were ever allowed out of their cage.
And this ideology remains intact through every Reiss descendant who inherits it. This is why, even with the Co-Ordinate, they refuse to destroy the Titan menace.
And with the Survey Corps being nothing more than a way of conveniently disposing of troublesome members of society while reminding the people of the scale of the threat that they faced, the First King could well have kept up this charade indefinitely - if it were not for the two alien elements he failed to predict: the first of which being Grisha Jaeger, and the second being the Warriors.
I don’t have enough evidence to set down anything clear for the aims of Grisha or the Warriors - the Warriors in particular are an increasingly difficult puzzle to solve - but the nature of the Walled world is now clear. The people within the Walls are the recipients of the grandest illusion of all time - victims of one man’s desperation for peace. This completes the strand of the major philosophical argument of the series, outlined by Eren in Chapter 1.
Security without freedom is the peace of livestock.
