“It may be illegal, but that’s what they’re designed for. Complete with an anus that passes convincing feces. I lived with him in the forest for months at a time. If he hadn’t seemed perfectly normal in every way, I would have known.”

“Designed to pass for human. I didn’t know. They wear special uniforms and talk in these leaden voices so that you can always tell.”

“My father—all the expendables—they spoke perfectly normally. They seemed like people. You’d have no reason to doubt them until you noticed that they live forever and don’t get older.”

“That’s such a crime.”

“There are worse crimes,” said Noxon. “Like sending a fleet to blow up a planet and kill billions of people.”

“Who would do that?” asked Deborah.

“That’s why I’m here,” said Noxon. “Because that’s what the people of Earth do to the people of Garden.”

“But your colony is the hope of humanity! After the comet tore up the Moon and nearly ended life on Earth, we knew we had to establish ourselves on another world so that one cosmic accident wouldn’t wipe us out. And the fact that you exist proves that it worked.”

“I know,” said Noxon. “Nobody knew that he’d not only leap the fold but go back 11,191 years into the past. Nobody knew that there’d be nineteen colonies on that one world, instead of one. Nobody knew that in those eleven millennia, we’d develop merpeople and this facemask and talking mice.”

“And timeshapers.”

“The Visitors who come to evaluate Garden don’t know about us,” said Noxon. Then he laughed at his own stupidity. “No, of course they know about us. We’re all over the ships’ logs. They definitely know about us. That’s probably why they destroy the planet—to eliminate the people who can go into the past and make erasures.”

“I can imagine they might find that terrifying.”

“But they would know that we already know about the destruction of Garden—that’s in the ship’s log from Odinfold. So they must expect that we’d attempt what I’m doing right now.”

“You have to admit that your return to Earth is a little improbable,” said Deborah.

“Yes,” said Noxon. “They might think they’re acting so fast that we wouldn’t have time to send one of us to Earth.”

“But it still seems . . . so drastic,” said Deborah. “We send out the ship. Seven years later, it leaps the fold. Then we invent faster-than-light starships and get to Garden at a time when we think you won’t even have had time to get there yet—it was supposed to take another seven years from the fold. Only you’ve already been there longer than the total of human history since the last glacial maximum.”

“Lots of surprises.”
