It will be an adventure, she said.

True. He didn’t know what else to say.

In the carpet she wrote Jackie Boone Went to the Moon.

It’s an awesome idea when you think of it, she said. Humanity, spreading through the galaxy. Star by star, ever outward. It’s our destiny. It’s what we ought to be doing. In fact I’ve heard people say that that’s where Hiroko is— that she and her people joined one of the first starships, the one to Barnard’s star. To start a new world. Spread viriditas.

It’s as likely as any other story, Nirgal said. And it was true; he could imagine Hiroko doing it, taking off again, joining the new diaspora, of humanity across the stars, settling the nearby planets and then on from there. A step out of the cradle. The end of prehistory.

He stared at her profile as she drew patterns on the carpet. This was the last time he would ever see her. For each of them it was as if the other were dying. That was true for a lot of the couples huddled silently together in this room. That people should leave everyone they knew.

And that was the First Hundred. That was why they had all been so strange— they had been willing to leave the people they knew, and go off with ninety-nine strangers. Some of them had been famous scientists, all of them had had parents, presumably. But none of them had had children. And none of them had had spouses, except for the six married couples who had been part of the hundred. Single childless people, middle-aged, ready for a fresh start. That was who they were. And now that was Jackie too: childless, single.

Nirgal looked away, looked back; there she was, flush in the light. Fine-grained gloss of black hair. She glanced up at him, looked back down. Wherever you go, she wrote, there you are.

She looked up at him. What do you think happened to us? she asked.

I don’t know.

They sat looking at the carpet. Through the window, in the cable chamber, an elevator levitated across the floor, hovering upright as it moved over a piste to the cable. It latched on, and a jetway snaked out and enveloped its outer side.

Don’t go, he wanted to say. Don’t go. Don’t leave this world forever. Don’t leave me. Remember the time the Sufis married us? Remember the time we made love by the heat of a volcano? Remember Zygote?

He said nothing. She remembered.

I don’t know.

He reached down and rubbed the nap of the carpet so that he erased the second you. With his forefinger he wrote we.

She smiled wistfully. Against all the years, what was a word?
