Denouement: David and Laura are living together happily, falling in love.

David crested the hill and watched the sea of green below him shift in the wind. The tide was coming in, and he could hear it now, like distant thunder.
The tide was brown, the animals that it consisted of moving like waves, gracefully crossing the plains. It was like a dream in many ways, the bison he thought would have been extinct by now running in a huge herd below him, trampling the waist high grasses, a single white one at the front.
The Movement’s primary community in Canada was simply amazing to David. They hadn’t so much given up on civilization as moved beyond it. They had fashioned a new mythology to live by that David was eager to explore.
For now, though, he turned and headed for home. His new home. He and Laura were falling in love, and the feeling welled in him like new life blossoming in his chest.
As he walked down the hill, he was overcome with the feeling of John’s presence. It only happened every once in a while now, and disappeared as quickly as it came. He took it as a reminder that past, present, or future, there was more to him than his current consciousness. He was at peace with this, knowing he would have a lifetime to explore its meaning.
For now though, he had a new life to begin.
