When he came back, if anyone was awake all they saw was a kid in a towel heading back to his bunk.
But he walked past his bunk and quietly sank down and slid under the last bunk, where the uncovered vent awaited him. His towel remained on the floor under the bunk, so that if anyone woke enough to notice that Bean's bunk was empty, they would see that his towel was missing and assume he had gone to the toilet.
It was no less painful this time, sliding into the vent, but once inside, Bean found that his exercise had paid off. He was able to slide down at an angle, always moving slowly enough to make no noise and to avoid snagging his skin on any protruding metal. He wanted no injuries he'd have to explain.
In the utter darkness of the air duct, he had to keep his mental map of the station constantly in mind. The faint nightlight of each barracks cast only enough light into the air ducts to allow him to make out the location of each vent. But what mattered was not the location of the other barracks on this level. Bean had to get either up or down to a deck where teachers lived and worked. Judging from the amount of time it took Dimak to get to their barracks the rare times that a quarrel demanded his attention, Bean assumed that his quarters were on another deck. And because Dimak always arrived breathing a little heavily, Bean also assumed it was a deck below their own level, not above--Dimak had to climb a ladder, not slide down a pole, to reach them.
Nevertheless, Bean had no intention of going down first. He had to see whether he could successfully climb to a higher deck before getting himself potentially trapped on a lower one.
So when he finally--after passing three barracks--came to a vertical shaft, he did not climb down. Instead, he probed the walls to see how much larger it was than the horizontals. It was much wider--Bean could not reach all the way across it. But it was only slightly deeper, front to back. That was good. As long as Bean didn't work too hard and sweat too much, friction between his skin and the front and back walls of the duct would allow him to inch his way upward. And in the vertical duct, he could face forward, giving his neck a much-needed respite from being perpetually turned to one side.
Downward was almost harder than upward, because once he started sliding it was harder to stop. He was also aware that the lower he went, the heavier he would become. And he had to keep checking the wall beside him, looking for another side duct.
But he didn't have to find it by probing, after all. He could see the side duct, because there was light in both directions. The teachers didn't have the same lights-out rules as the students, and their quarters were smaller, so that vents came more frequently, spilling more light into the duct.
In the first room, a teacher was awake and working at his desk. The trouble was that Bean, peering out of a vent screen near the floor, could not see a thing he was typing.
It would be that way in all the rooms. The floor vents would not work for him. He had to get into the air-intake system.
Back to the vertical duct. The wind was coming from above, and so that was where he had to go if he was to cross over from one system to another. His only hope was that the duct system would have an access door before he reached the fans, and that he would be able to find it in the dark.
Heading always into the wind, and finding himself noticeably lighter after climbing past seven decks, he finally reached a wider area with a small light strip. The fans were much louder, but he still wasn't near enough to see them. It didn't matter. He would be out of this wind.
The access door was clearly marked. It also might be wired to sound an alarm if it was opened. But he doubted it. That was the kind of thing that was done in Rotterdam to guard against burglars. Burglary wasn't a serious problem on space stations. This door would only have been alarmed if all doors in the station were fitted with alarms. He'd find out soon enough.
He opened the door, slipped out into a faintly lighted space, closed the door behind him.
The structure of the station was visible here, the beams, the sections of metal plating. There were no solid surfaces. The room was also noticeably colder, and not just because he was out of the hot wind. Cold hard space was on the other side of those curved plates. The furnaces might be located here, but the insulation was very good, and they had not bothered to pump much of that hot air into this space, relying instead on seepage to heat it. Bean hadn't been this cold since Rotterdam . . . but compared to wearing thin clothing in the winter streets with the wind off the North Sea, this was still almost balmy. It annoyed Bean that he had become so pampered here that he even cared about such a slight chill. And yet he couldn't keep himself from shivering a couple of times. Even in Rotterdam, he hadn't been naked.
Following the ductwork, he climbed up the workmen's ladderways to the furnaces and then found the air-intake ducts and followed them back down. It was easy to find an access door and enter the main vertical duct.
Because the air in the intake system did not have to be under positive pressure, the ducts did not have to be so narrow. Also, this was the part of the system where dirt had to be caught and removed, so it was more important to maintain access; by the time air got past the furnaces, it was already as clean as it was ever going to get. So instead of shinnying up and down narrow shafts, Bean scrambled easily down a ladder, and in the low light still had no trouble reading the signs telling which deck each side opening led to.
The side passages weren't really ducts at all. Instead, they consisted of the entire space between the ceiling of one corridor and the floor of the one above. All the wiring was here, and the water pipes--hot, cold, sewer. And besides the strips of dim worklights, the space was frequently lighted by the vents on both sides of the space--those same narrow strips of vent openings that Bean had seen from the floor below on his first excursion.
Now he could see easily down into each teacher's quarters. He crept along, making as little noise as possible--a skill he had perfected prowling through Rotterdam. He quickly found what he was looking for--a teacher who was awake, but not working at his desk. The man was not well known to Bean, because he supervised an older group of launchies and did not teach any of the classes Bean was taking. He was heading for a shower. That meant he would come back to the room and, perhaps, would sign in again, allowing Bean to have a chance at getting both his log-in name and his password.
No doubt the teachers changed passwords often, so whatever he got wouldn't last long. Moreover, it was always possible that attempting to use a teacher's password on a student desk might set off some kind of alarm. But Bean doubted it. The whole security system was designed to shut students out, to monitor student behavior. The teachers would not be so closely watched. They frequently worked on their desks at odd hours, and they also frequently signed on to student desks during the day to call on their more powerful tools to help solve a student's problem or give a student more personalized computer resources. Bean was reasonably sure that the risk of discovery was outweighed by the benefits of snagging a teacher's identity.
While he waited, he heard voices a few rooms up. He wasn't quite close enough to make out the words. Did he dare risk missing the bather's return?
Moments later he was looking down into the quarters of . . . Dimak himself. Interesting. He was talking to a man whose holographic image appeared in the air over his desk. Colonel Graff, Bean realized. The commandant of Battle School.
"My strategy was simple enough," Graff was saying. "I gave in and got her access to the stuff she wanted. She was right, I can't get good answers from her unless I let her see the data she's asking for."
"So did she give you any answers?"
"No, too soon. But she gave me a very good question."
"Which is?"
"Whether the boy is actually human."
"Oh, come on. Does she think he's a Bugger larva in a human suit?"
"Nothing to do with the Buggers. Genetically enhanced. It would explain a lot."
"But still human, then."
"Isn't that debatable? The difference between humans and c
himpanzees is genetically slight. Between humans and neanderthals it had to be minute. How much difference would it take for him to be a different species?"
"Philosophically interesting, but in practical terms--"
"In practical terms, we don't know what this kid will do. There's no data on his species. He's a primate, which suggests certain regularities, but we can't assume anything about his motivations that--"
"Sir, with all due respect, he's still a kid. He's a human being. He's not some alien--"
"That's precisely what we've got to find out before we determine how much we can rely on him. And that's why you are to watch him even more carefully. If you can't get him into the mind game, then find some other way to figure out what makes him tick. Because we can't use him until we know just how much we can rely on him."
Interesting that they openly call it the mind game among themselves, thought Bean.
Then he realized what they were saying. "Can't get him into the mind game." As far as Bean knew, he was the only kid who didn't play the fantasy game. They were talking about him. New species. Genetically altered. Bean felt his heart pounding in his chest. What am I? Not just smart, but . . . different.
"What about the breach of security?" Dimak asked.
"That's the other thing. You've got to figure out what he knows. Or at least how likely he is to spill it to any other kids. That's the greatest danger right now. Is the possibility of this kid being the commander we need great enough to balance the risk of breaching security and collapsing the program? I thought with Ender we had an all-or-nothing long-odds bet, but this one makes Ender look like a sure thing."
"I didn't think of you as a gambler, sir."
"I'm not. But sometimes you're forced into the game."
"I'm on it, sir."
"Encrypt everything you send me on him. No names. No discussions with other teachers beyond the normal. Contain this."
"Of course."
"If the only way we can beat the Buggers is to replace ourselves with a new species, Dimak, then have we really saved humanity?"
"One kid is not replacement of a species," said Dimak.
"Foot in the door. Camel's nose in the tent. Give them an inch."
"Them, sir?"
"Yes, I'm paranoid and xenophobic. That's how I got this job. Cultivate those virtues and you, too, might rise to my lofty station."
Dimak laughed. Graff didn't. His head disappeared from the display.
Bean had the discipline to remember that he was waiting to get a password. He crept back to the bather's room.
Still not back.
What breach of security were they talking about? It must have been recent, for them to be discussing it with such urgency. That meant it had to be Bean's conversation with Dimak about what was really going on with the Battle School. And yet his guess that the battle had already happened could not be it, or Dimak and Graff would not be talking about how he might be the only way they could beat the Buggers. If the Buggers were still unbeaten, the breach of security had to be something else.
It could still be that his earlier guess was partly right, and Battle School existed as much to strip the Earth of good commanders as to beat the Buggers. Graff and Dimak's fear might be that Bean would let other kids in on the secret. For some of them, at least, it might rekindle their loyalty to the nation or ethnic group or ideology of their parents.
And since Bean had definitely been planning to probe the loyalties of other students over the next months and years, he now would have to be doubly cautious not to let his pattern of conversation attract the attention of the teachers. All he needed to know was which of the best and brightest kids had the strongest home loyalties. Of course, for that Bean would need to figure out just how loyalty worked, so he would have some idea of how to weaken it or strengthen it, how to exploit it or turn it.
But just because this first guess of Bean's could explain their words didn't mean it was right. And just because the final Bugger war had not yet been fought didn't mean his initial guess was completely wrong. They might, for instance, have launched a fleet against the Bugger home world years ago, but were still preparing commanders to fight off an invasion fleet now approaching Earth. In that case, the security breach Graff and Dimak feared was that Bean would frighten others by letting them know how urgent and dire the situation of humanity was.
The irony was that of all the children Bean had ever known, none could keep a secret as well as he did. Not even Achilles, for in refusing his share of Poke's bread, he had tipped his hand.
Bean could keep a secret, but he also knew that sometimes you had to give some hint of what you knew in order to get more information. That was what had prompted Bean's conversation with Dimak. It was dangerous, but in the long run, if he could keep them from removing him from the school entirely in order to silence him--not to mention keeping them from killing him--he had learned more important information than he had given them. In the end, the only things they could learn from him were about himself. And what he learned from them was about everything else--a much larger pool of knowledge.
Himself. That was their puzzle--who he was. Silly to be concerned about whether he was human. What else could he be? He had never seen any child show any desire or emotion that he himself had not felt. The only difference was that Bean was stronger, and did not let his fleeting needs and passions control his actions. Did that make him alien? He was human--only better.
The teacher came back into the room. He hung up his damp towel, but even before he dressed he sat back down and logged on. Bean watched his fingers move over the keys. It was so quick. A blur of keystrokes. He would have to replay the memory in his mind many times to make sure. But at least he had seen it; nothing obstructed his view.
Bean crawled back toward the vertical intake shaft. The evening's expedition had already taken as long as he dared--he needed his sleep, and every minute away increased the risk of chance discovery.
In fact, he had been very lucky on this first foray through the ducts. To happen to hear Dimak and Graff conversing about him, to happen to watch a teacher who conveniently gave him a clear view of his log-in. For a moment it crossed Bean's mind that they might know he was in the air system, might even have staged all this for him, to see what he'd do. It might be just one more experiment.
No. It wasn't just luck that this teacher showed him the log-in. Bean had chosen to watch him because he was going to shower, because his desk was sitting on the table in such a way that Bean had a reasonable chance of seeing the log-in. It was an intelligent choice on Bean's part. He had gone with the best odds, and it paid off.
As for Dimak and Graff, it might have been chance that he overheard them talking, but it was his own choice to move closer at once in order to hear. And, come to think of it, he had chosen to go exploring in the ducts because of precisely the same event that had prompted Graff and Dimak to be so concerned. Nor was it a surprise that their conversation happened after lights-out for the children--that's when things would have quieted down, and, with duties done, there would be time for a conversation without Graff calling Dimak in for a special meeting, which might arouse questions in the minds of the other teachers. Not luck, really--Bean had made his own luck. He saw the log-in and overheard the conversation because he had made that quick decision to get into the intake system and acted on it at once.
He had always made his own luck.
Maybe that was something that went along with whatever genetic alteration Graff had found out about.
She, they had said. She had raised the question of whether Bean was genetically human. Some woman who was searching for information, and Graff had given in, was letting her have access to facts that had been hidden from her. That meant that he would receive more answers from this woman as she began to use that new data. More answers about Bean's origins.
Could it be Sister Carlotta who had doubted Bean's humanity?
Sister Carlotta, who wept when he left her and went into space? S
ister Carlotta, who loved him as a mother loves her child? How could she doubt him?
If they wanted to find some inhuman human, some alien in a human suit, they ought to take a good long look at a nun who embraces a child as her own, and then goes around casting doubt about whether he's a real boy. The opposite of Pinocchio's fairy. She touches a real boy and turns him into something awful and fearful.
It could not have been Sister Carlotta they were talking about. Just another woman. His guess that it might be her was simply wrong, just like his guess that the final battle with the Buggers had already happened. That's why Bean never fully trusted his own guesses. He acted on them, but always kept himself open to the possibility that his interpretations might be wrong.
Besides, his problem was not figuring out whether he really was human or not. Whatever he was, he was himself and must act in such a way as to not only stay alive but also get as much control over his own future as possible. The only danger to him was that they were concerned about the issue of his possible genetic alteration. Bean's task was therefore to appear so normal that their fears on that score would be dispelled.
But how could he pretend to be normal? He hadn't been brought here because he was normal, he was brought here because he was extraordinary. For that matter, so were all the other kids. And the school put so much strain on them that some became downright odd. Like Bonzo Madrid, with his loud vendetta against Ender Wiggin. So in fact, Bean shouldn't appear normal, he should appear weird in the expected ways.
Impossible to fake that. He didn't know yet what signs the teachers were looking for in the behavior of the children here. He could find ten things to do, and do them, never guessing that there were ninety things he hadn't noticed.
No, what he had to do was not to act in predictable ways, but to become what they hoped their perfect commander would be.
When he got back to his barracks, climbed back up to his bunk, and checked the time on his desk, he found that he had done it all in less than an hour. He put away his desk and lay there replaying in his mind the image in his memory of the teacher's fingers, logging in. When he was reasonably certain of what the log-in and password were, he allowed himself to drift toward sleep.
