Who’s actually in charge?
On my third watch and my wife and I are still confused about who’s in control? Eren, Ymir, or is it just the Amoeba worm thing?
Eren said that he was able to view past present and future events but was his fate/story already written when he was born by the worm? In this scenario it would make sense why his whole mantra is “you have to fight to live” and repeats that time and time again throughout. Seeing what his fate was with the rumbling it doesn’t seem like he’s a genocidal maniac bent on 0’ing Earth’s population outside the walls. Saying “you have to fight” is not only to himself but also to his friends because he knows the only way to alter his fate is if they fight him.
His other arc was to kill every single titan which he does succeed in doing but with the how the end credits played it looks like the whole loop is starting over with the man peering into the tree. On that note would a piece of the amoeba have stayed in his head and seeped into the ground below the tree?
