Nostalgia

A young man with spiky blond hair and an orange and blue outfit stands in the foreground, looking toward a group of three other characters in a mountainous outdoor setting with a large metal tank and a tower in the background; the scene cuts to a close-up of a man with short hair and a serious expression, then to a group of four characters standing together, followed by a sepia-toned version of the same group, and finally back to the man's face, which changes expression from stern to slightly surprised.
