I've been on a long break from SnK, and man oh man.
I feel like Eren's goal isn't to destroy the world. This is the outside world he and Armin longed for so much. Why would he destroy it? His goal is to bring the world together. And the best way to do so is to have them band together and defeat a common enemy; himself. He's ready to go down in history as a genocidal monster to bring peace to the world. Like someone else here so aptly said, he's doing a Lelouch.
Or he's actually just doing it to destroy the world and the enemies of Paradis. I dunno.
Samuel...isn't he the guy Sasha saved during the attack on Trost? I don't know why but I feel it's a cruel twist of fate that Connie, the person who was arguably the most affected by Sasha's death (still wondering whether they were romantically linked at that point or not or just best buddies), ends up killing someone that she saved years ago. That's dark. He just can't catch a break.
I really need to comment on how much Gabi has grown on me too. I used to hate her, and when I say hate I mean hate. I wanted her to die so bad. Especially after killing best girl Sasha. But I feel like she's redeemed herself now. It warmed my heart to see her and Kaya hug, and I'm sure Sasha looked down from potato heaven and smiled as well. Won't forgive her for what she did, but I now want her and Falco to survive all this, eventually marry and be happy.
Lastly, Floch needs to die. Preferrably next chapter.
