The admiral sat down against the visiscreen, his huge shoulders slumped and an expression of dismay on his broad face.

"Tell me, you miserable robot and you ridiculous human being, is there any slight possibility of my being taken forward to a time when human beings exist on Earth?"

"Yes, sir," said Jeff. "Norby-let's try."

"Aye, aye, Captain," said Norby, overdoing it as usual.

The Hopeful shivered and shook, and so did Jeff. What if he and Norby got things so mixed up that they were all lost forever?

"I can't see a thing," said Yobo as he peered at the visiscreen. "You've brought us close enough to Earth to be inside the cloud cover. That's dangerous, a little closer and…"

Jeff said hastily, "I'll bring the Hopeful closer through ordinary space. There'll be no danger."

The Hopeful poked her nose out of the cloud and the visiscreen magnified the ground. They were over a continent; in fact, they were over a city. In view were buildings and people.

Jeff said, "We're back to human beings and civilization, Admiral. "

Norby said, "And the Coliseum. Jeff, it's Roman times again. We tied into where and when I was before, so maybe now I'll get to see how that gladiator came out in the fight. They took me to the lion cage just when the fight was starting. Big husky fellow, that gladiator. Reminds me of you, Admiral."

"You mean to say," said Yobo, apparently suppressing a snarl, "that your fascination with this period of history had caused what passes for a mind in that tin hat of yours to get mixed up and drag all of us into Roman times just so that you would have a chance to find out what happened to a gladiator?"

"I didn't exactly mean to do it, sir," said Norby. "I mean, even if I'd intended to do it, I couldn't always guarantee that I could. It's not my fault that I've got emotive circuits and imagination and special talents that get mixed up. I can't help being different from other robots."

Jeff manipulated the controls of the Hopeful and the little ship rose back into the clouds. Hiding a smile, he said, "I think we'd better go someplace else. We don't want to be seen and cause any changes in history."

"Changes in-history?" The admiral mopped his brow. "I suppose that if our scientists tried to copy talents such as this, we'd end up with the constant danger of messing up the past and changing history in such a way that none of us would exist?"

"I think you're right," said Jeff. "Maybe the whole human race wouldn't exist." He touched Norby.

— Mission accomplished, Norby.

— Right, Jeff. He's convinced I'm unreliable.

— Well, you are, aren't you?

— Not really. It's just that…

— Never mind. Now let's really go home.

Only they didn't.

"Where are we now?" Yobo asked weakly.

"Norby," Jeff asked, "where are we?"

Norby was plugging himself into various parts of the computer rather frantically. "I don't know, Jeff. You got my emotive circuits stirred up and something's gone wrong."

"Can't see a thing in the visiscreen," said Yobo. "Everything is all shiny and vague."

"The screen's polarized," said Jeff in horror. "The light outside is so strong that the Hopeful is compensating for it by not letting it show on the visiscreen. And the instrument panel shows that the outside of the hull is getting hotter and hotter."

"I think we're stuck, Jeff," said Norby, his voice tinny.

"Unstick us," yelled Jeff. "We humans won't be able to live much longer if the heat goes any higher!"

"Neither will I," said Norby. "I have delicate brain mechanisms."..

"Then put them to work on solving this problem," roared Yobo.

Jeff's head was pounding and he had never been so frightened in his life. "Have we come inside a star?"

"No, Cadet. Impossible! We'd be dead in a microsecond."

"Then where…Look, Admiral, the readings show a gravitational pull on us. We're being dragged in, or down, somewhere."

"I have deciphered the incoming data," said Norby importantly, "and this is the situation. We are quite close to a star much dimmer than Earth's sun, close enough so that it is heating us rapidly and is pulling at us strongly."

"And we are spiralling inward under that pull," said Jeff. "Norby-get us out of here quickly."

"But Jeff, my circuits are resonating improperly. I can't."

Jeff touched him.

— Norby, I bought and paid for you, and until you go back to Jamya, you are my robot. Join minds with me and we'll both try to move the Hopeful back into hyperspace.

— But Jeff, we're both mixed up when it comes to time travel.

— We tried to show how mixed up we were to fool the admiral. But now we're in trouble, and it serves us right. So let's try to move again and let's try not to be mixed up.

They touched each other and the control panel and suddenly Jeff felt as if he were the Hopeful herself.

He was not Jefferson Wells. He was not Norby. He was just the ship, fighting to save her life and the lives of three sentient beings she carried-and winning.

"Oof!" said Yobo, rubbing his bald head. "That was a rough trip."

"We're out!" Jeff picked up Norby and jumped around the control room. "We did it!"

"This is our own time exactly," said Norby proudly, his little arms waving triumphantly.

"Quiet!" roared Yobo. "I see Space Command ahead, and I have never before thought it to be the most beautiful object in the Universe, but I certainly think so now. Take me home."

The great artificial world of Space Command Spome, the circling wheel of the fleet's space home (for which "spome" was the universally used term), hung like a brilliant three-dimensional pattern in the blackness of space.

In the distance was Mars, around which the spome circled, and Jeff could see the lights of the small shuttle boats going back and forth. People took shuttles because the transmits were so expansive, but soon, with hyperdrive, human beings would be able to spread through the galaxy and establish a great empire of the stars.

— Maybe that's not such a great idea, Jeff. Jeff was still holding Norby.

— The Mentors will be traveling, too, Norby. There will be room for both of us.

— And I'll be a sort of go-between, won't I. I'm part both, aren't I, Jeff?"

Jeff laughed.

— Well, let's assume an optimistic attitude, Norby. Or at least have a sense of humor about it. Everything might go well.

But Admiral Yobo shouted impatiently, "Let's get a move on, Cadet!"

Norby was gone!

Jeff waited disconsolately in the old Wells apartment on Manhattan Island, Earth. He stared out the window at Central Park, where the leaves were turning to gold and flame because it was now autumn. The dying of the year seemed to resonate inside his chest and he felt as though something were dying within him, too.

Admiral Yobo had sworn strict confidentiality concerning Norby's other secret. In fact, the admiral had shuddered and said, "I will never mention to anyone that your robot is capable of time travel. If he's the only being in the universe capable of it, I would be relieved. If even he were not capable of it, I would be still more relieved."

"I understand, sir."

"So we can forget about having our scientists go through him to dig up things too dangerous for anyone to have. In fact, if he weren't useful and your friend, I would be tempted to put him into a stasis chamber," he had said.

"No, sir. Please don't do that."

The admiral ignored the plea. "We can only wait and hope that the Mentors will consider being friends with the Federation and give us the secret of the Others' hyperdrive."

"I'm sure the fleet scientists will discover hyperdrive for themselves just as quickly."

"Probably. They've already expressed optimism over the matter of the gold collar, and that's the first step, I suppose. Just keep your robot out of their way so that there won't be any missteps!"
