Right, you know how Scout has dog tags? I don't know if it's been said who's they were, but I doubt Scout's the kind to join the army, and I really don't think he's making a fashion statement, so what if they were, say, his eldest brother's? He always looked out for Scout and patched him up when he got into a scrap, and never told on him to their mother. One day he had to leave, he wanted to protect the rest of the country like he did Scout. Only thing is, he never came back.
