>>219974829Think about this for a second. Eren and Armin are back on the beach, the place where possibly the most impactful moment in the entire manga happened, during their last conversation and the end of Eren's character. Remember the anime's swelling, melancholy music, the tragedy of the reveal that they're isolated and hated by the whole world, their dream coming true only to be dashed in that same instant.
Isayama took that setting, that moment, and made it into a joke where Eren complains about how he doesn't want to get NTRed after he's dead and Armin calls him pathetic.
