They looked so normal, the older, grey-haired man in the soft cap, the tall, younger man, casting their homemade flies, talking quietly.

They talked about “simulations” that mixed history with mystery, about a massive game of hide and seek, about captures and escapes. They talked about love, about father and son relationships, about science and emotion, about unresolved issues. And they quietly fished.
