Oh no a cave in! (Peter, Lily, Bruce)
Bruce didn't much care about panning for gold. Growing up in the lap of luxury had made him used to wealth, but the teachings of Marcus Aurelius and more, his butler, meant he didn't exactly need it. Besides, it had only been once that they had let them buy anything beyond candy and hair gel, and most beyond that was provided.
But they didn't often get caves.
Perhaps his favorite scenario had been the Pokemon one, where he spent five days alone in a cave in the dark before Diana tracked him down and while bats still unnerved him, he was fascinated too. He had taken the chance to likewise explore the mine in the desert, surrounding himself with silence that calmed his turbulent mind, darkness that mirrored that within him, and promise beyond anything else.
And he had been there, for who knew how long, when he heard--no felt--a rumbling.
