Steve liked the gym because it hadn't changed. Heavy bags hadn't changed. Boxing rings hadn't changed. The gym smell, of sweat and canvas, hadn't changed.
Steve didn't like going out in public, in the city. Too much had changed. There was too much technology, billboards scrolled and changed. Cars looked odd. People walked around with little boxes attached to their ear, locked in their own little world. No one looked at anyone else as they walked. The changes were what had stopped him in his tracks when he "escaped" from SHIELD. Nothing was recognizable.
Steve had been a city kid, but he had gone outside the city with Bucky. Once he got out of the city, he found that there was much that was the same. Small towns still tended to be friendly but cautious of outsiders. Cows were the same. Dogs were the same. The smell of growing things was the same.
Steve's uniform had changed. It looked … fancier. He missed the uniform he had helped put together with Peggy. It looked functional, no-nonsense. This new uniform was functional, but it wasn't the same.
Steve found that bad guys hadn't changed. Even if they came from further away, they still wanted to rule the world. They still had to threaten everyone around them that didn't agree with them with destruction.
Steve's teammates had changed. They weren't professional soldiers. They were scientists, assassins, and a demi-god.
Steve realized that war hadn't changed. The weapons had become more sophisticated, but the purpose of the weapons was the same: killing the enemy. War was still about defending one side against the other side. Too many people died as a result of war. That hadn't changed, either.
Steve found that people didn't change. There were still good people and bad people, and just because someone was arrogant or annoying didn't mean they were bad. They were simply a person, with good points and bad points, and annoying points.
