“You could not have shut off your own Wall until all the others were shut off,” said the expendable. “You would have had to use it last in any case. So when the other Walls are down, you will return home, get the last jewel, and shut down the last Wall.”
“We will?” asked Param.
“Why else would you have passed through the Wall?” asked the expendable.
“To save our lives,” said Rigg. “There are people on the other side trying to kill us.”
Umbo leaned back so he could look through the Wall again at the place where Mother and General Citizen sat astride their horses. “You’d think they’d look over and notice that Param and I are already here,” said Umbo.
“It wouldn’t cross their minds,” said Param.
“You’re both on the other side of Loaf and Olivenko,” said Rigg. “They can’t see you unless you lean out to look.”
The expendable indicated for Rigg to put away the jewels. “So you are truly ignorant of what you’re here for,” he said.
Rigg gathered the jewels. “No,” he said. “We know exactly why we’re here. We just don’t know why you think we’re here, or why Father—the Golden Man—why he gave me the jewels and set us on this path.”
“We choose our own purposes now,” said Param.
“We’ll see how that works out for you,” said the expendable. He stood up and started to walk away.
“Wait!” called Loaf.
The expendable kept walking.
“You say it,” said Loaf. “You make him wait, Rigg.”
“Wait,” said Rigg. “Come back.”
The expendable came back. “I hate this,” murmured Rigg as the expendable approached. “I don’t want to command anybody.”
“If it’s any consolation,” said Umbo, “you don’t have any authority at all over us.”
“We need your help just to survive here,” said Rigg. “We don’t speak the languages.”
“Yes you do,” said the expendable.
“We didn’t understand a word you were saying before,” said Rigg.
“Nevertheless, all the languages ever spoken in the world are contained within the Wall. If it were not so, it could not speak to you.”
“So the Wall knows the languages,” said Rigg.
“And having passed through the Wall, so do you,” said the expendable. “It may take time for any particular language to recognize itself and waken in your memory, but it will be there.”
“I’m hungry,” said Loaf. “I’ve had enough talk.”
“Let’s get out of sight of General Citizen and his clowns,” said Olivenko. “I’m done with them.”
“For now,” said Param. “Till we go back.”
“And why would we go back?” asked Loaf.
“To get the last jewel,” said Param. “To shut off this last Wall.”
“So you think we should do what these expendables intend for us to do?” asked Rigg.
“I think they’ll give us no peace until we do,” said Param. “I think his supposed obedience is a fraud, and they’re going to keep controlling us the way they’ve been doing all along.”
“In case anyone’s forgotten,” said Olivenko, “not all the people in other wallfolds are nice. Not even the people in our wallfold are nice. What would General Citizen do, if this Wall disappeared right now?”
“Come over here and kill us all,” said Umbo.
“Not if I killed him first,” said Loaf.
“Wars of conquest,” said Olivenko. “Until now, the great achievement of the Sessamoto was to unite the entire wallfold under a single government. But if the walls disappear, how long before we try to conquer the world? Or the people of some other wallfold try to conquer us? Humans are humans, I assume, in every wallfold.” He turned to the expendable. “Or has human nature changed in any of them? Is there a version of the human race that has abandoned predation and territoriality?”
“I wouldn’t know,” said the expendable. “We pretty much stick to learning about our own wallfold.”
Rigg said, “Then ask the others. Find out. If you want us to take down the Walls, we have to know the consequences.”
“I think that’s something that you’ll need to discover for yourselves,” said the expendable.
“So much for obedience,” said Param.
The expendable turned to her. “The Walls have never been shut off before, or crossed, until the five of you. We don’t know how the human beings of each wallfold will react. I cannot tell you what I do not know. I told you that I would obey any command that I had the power to obey.”
“So the responsibility for the whole world is in our hands,” said Rigg.
“Your hands,” said Umbo. “You have the jewels.”
“Come on,” said Rigg. “We’re in this together. Please.”
Umbo laughed. “Lighten up, Rigg. What else have we got to pass the time, if not taking down all the Walls in the world?”
“And finding out what they’re not telling us,” said Param. “Count on it, they’re still lying to us. You notice he’s not even denying it.”
The expendable regarded her calmly. “I’m not agreeing, either.”
“Which is just another form of lying,” said Param.
“You cannot lie,” said the expendable, “if you do not know the truth. You can only be wrong, or silent. I prefer silence to error, and since I do not know when I am in error, silence is the best choice unless I am forced to speak.”
“Not just a liar,” said Param, “but a philosopher.”
“Tell us the truth when we ask you questions,” said Rigg, “or whatever you believe to be the truth based on current information. And answer everybody’s questions, not just mine.”
“All right,” said the expendable.
“What is your name?” Rigg asked the expendable.
“I don’t have a name,” said the expendable.
“But I need a name for you. And a name for the one I called Father.”
“The active expendable is referred to by the name of the wallfold in which he serves,” said the expendable.
“So what is the name of that wallfold? The one we were born in? The one we just left?”
“We call it Ramfold,” said the expendable. “So we call your active expendable ‘Ram.’”
“And this wallfold?” asked Umbo. “And your name?”
“Vadesh,” said the expendable. “This is Vadeshfold, and I am called Vadesh.”
“Did you notice that he actually answered somebody who wasn’t me?” said Rigg. “That’s progress.”
“Is there fresh water around here?” asked Loaf. “Drinkable water? Clean water? Safe water? In quantities we can use to refill our water bags—do I need to be more specific?”
“I’ll lead you to water,” said Vadesh. “But I can’t make you drink.”
Rigg looked at the others, puzzled, then turned back to Vadesh. “Why would you say that? Why would you need to make us drink?”
“It’s an old saying,” said Vadesh. “On Earth, the world where the human race was born. In one of the languages of Earth. It is twelve thousand years old. ‘You can lead a horse to water, but you can’t make it drink.’”
“Thank you for the history lesson,” said Olivenko.
“And the lesson in equine behavior,” said Param.
Rigg chuckled at their ironic humor as Vadesh led them away from the Wall, toward a not-so-distant line of trees. But he noticed that Vadesh made no comment on their jests, and a thought occurred to him. “Vadesh,” he said, “your references to the world where humans came from, and teaching us a saying from twelve thousand years ago. Is there some reason why we might need to know about Earth?”
“Yes,” said Vadesh.
“And what is that reason?” asked Rigg.
Vadesh said nothing.
“Does your silence mean that you don’t know?” asked Rigg. “Or that you just don’t want to tell us?”
“I cannot predict the answer to your question with anything approaching accuracy or certainty. But you will need to know many things about Earth, and you will need to know them soon.”
