Finally got my friend to stop calling the 'Attack on Titan' ending a plot hole
He kept saying the whole final twist came out of nowhere, but I sat him down and we rewatched the first season together. I pointed out three specific scenes, like the one where Eren's dad talks about the basement in episode 5, that directly set it up. It took about an hour, but he finally saw the clues were there the whole time. It just needed you to pay attention to the smaller details, not just the big fights. Has anyone else had to walk someone back through an anime because they missed the setup?
