"It's a diffraction band. The other mottling is caused by the solar disc blurring the edges, but this arc is caused by sunlight diffracting past the sharp edge of a leaf."
"So?"
"Prime Intellect uses a ray-tracing algorithm to simulate light. You don't get diffraction effects unless you specifically ask for them."
"So there are a lot of details. There are also a lot of smells. I'm still getting used to it."
"Caroline, I think this world is represented at a molecular level. It's not just another virtual landscape. This is the Earth. And we're..." He faltered for a moment. "I think we're mortal."
"You can't be serious."
He stood up. "Look around. See these holes in the ground? Those are basements. I know this place. This was a park. This is where I was during the Night of Miracles. It's
ChipTec
. Over there is the Prime Intellect Complex, and that hole was the Administration Building..."
"I woke up at the bottom of one of these holes."
Lawrence nodded. "That's probably the hospital where you were..."
He didn't finish the sentence because Caroline whooped and hit him with a flying tackle, knocking him flat. She straddled him and pinned his arms. It was impossible to tell whether her expression represented outrage or some kind of manic joy. "Are you telling me it
worked?
" she yelled. "We're

"
He was choking back tears. "Did it work? Did it work, Caroline? Sure, it undid the Change, it undid the Night of Miracles, and it also erased every trace of about ten thousand years of civilization and dumped us here naked and alone without even a fish hook. Let's not even talk about what happened to the rest of the human population, who didn't get caught up in whatever automatic process it set up to do this. Let's not..."
He dissolved into sobs. Caroline let him cry a little, then let go of his arms and lay on top of him. Perhaps responding to some primitive instinct, he hugged her. She let him. It was one thing, she reflected, for her to face this situation; she'd spent hundreds of years deliberately engineering far worse tests for herself. But for Lawrence, who had sunk into a fearful conservatism, it was shattering.
"I killed them all," Lawrence finally sobbed. "How could I...if only I had never lived, none of this..."
