I feel this intense feeling of relief almost like an impression of finality since the whole titan serum debacle ended. Armin is safe. Eren and Armin hugged. Eren was overcome with emotion. Almost like I don’t need anything else from the story? I know I’m going to keep reading the story of course but I’m just so damn satisfied that I really can’t help but smile. I hope my fellow readers that love Armin (and the trio) feel the same.
