They'd reached an exit now, and Halloran led them outside. "Wait a second—we're on the wrong side of the building," Jonny said, stopping and looking around. "The practice field's that way, isn't it?"

"Yep," Halloran nodded cheerfully. "But for Cobras cross-country's faster than all those hallways."

"Cross-country as in around?" Jonny asked, peering down the eight-story structure heading halfway to infinity in both directions.

"As in over," Halloran corrected. Facing the wall, he flexed his knees. "Last one to the top's a gum-bumbler—and any windows you break come out of your pay."

The second week passed as the first had, with long days of Cobra exercises and equally long—or so it seemed—evenings of military theory. Every day or two they received new neckwrap computer modules, each one allowing a new weapon in their arsenals to be brought into play. Jonny learned how to use his sonic weapons and how to retune them in the event that the Trofts turned out to be particularly susceptible to specific frequencies; learned how to trigger his arcthrower, a blast of high voltage traveling down the ionization path burned by his right fingertip laser, and how to efficiently fry electronic gear with it; and, finally, learned now to handle the antiarmor laser in his left calf, simultaneously the most powerful and most awkward of his weapons. Pointing downward along the tibia, its beam was guided through his ankle by optical fibers to emerge through a flexible focusing lens in the bottom of his heel. Special boots were handed out with the computer modules that day, and as he tried to learn how to shoot while standing on one leg, Jonny joined the rest of the trainees in roundly cursing the idiot who'd been responsible for that particular design. Bai claimed they'd find out how versatile the laser was once they had their programmed reflexes, but no one seriously believed him.

But through all the work, practice, and memorization—through the physical and mental fatigue—two unexpected observations managed to penetrate Jonny's consciousness. First, that Viljo's taunts disappeared almost entirely after the mess hall incident, though the other remained cool toward him; and second, that Bai really did tend to single Jonny out for special notice.

The latter bothered him more than he cared to admit. Viljo's suggestion that the Moreau family had somehow bribed the instructor was absurd, of course... but at least some of the other trainees must have overheard the allegation, and if Jonny could pick up on Bai's pattern so could they. What did they think about it? Did they imagine it implied he was getting special privileges off the training field?

More to the point, why was Bai doing it?

He wasn't the best of the trainees, certainly—Deutsch alone proved that. Nor, he thought, was he the worst. The youngest? Oldest? Closest physically to some old friend/enemy? Or—and it was a chilling thought—did Bai secretly share some of Viljo's biases?

But whatever the reason, there was no response he could think of except the one he was already using: to endure with as much outer stoicism and inner calm as he could manage. It proved more effective than he'd expected it to, and by the time the second week drew to a close he was able to face Bai's comments or work alongside Viljo with only the slightest nervousness. How much the other trainees noticed his new attitude he didn't know, but Halloran made at least one comment on it.

And then the third week began; and all that had gone before paled to the relative significance of a quiet summer's stroll... because on the first day of that week they began working with their computerized reflexes.

"It's dead simple," Bai told them, gesturing to the ceiling barely two meters above their heads. "You first key your targeting lock on the spot where you intend to hit, and then jump, giving your body a backward motion as you do so." He bent his knees and straightened them, simultaneously arching his back. "Then just relax and let the computer run your servos. Try not to fight it, by the way; you'll just strain your muscles and make it harder for your subconscious to adjust to having something else in charge of your body. Questions? Um? All right. Aldred, target lock: go."

One by one they all performed the ceiling jump that had been their first introduction to Cobra abilities those four long weeks ago. Jonny had thought himself adequately prepared; but when his turn came he found out otherwise. Nothing—not even the now-familiar servo enhancement effect—could quite compare with the essential decoupling of body and mind that the automatic reflexes entailed. Fortunately, the maneuver was over so quickly that he didn't have time to feel more than a very brief panic before his feet were back on the floor and his muscles returned to his control. Only later did he realize that Bai had probably started them with the ceiling jump for precisely that reason.

They went through the exercise five times each, and with each flawless jump Jonny's anxiety and general feeling of weirdness eased, until he was feeling almost comfortable with his new copilot.

As he should have expected, though, he wasn't allowed to feel comfortable for long.

They stood atop a five-story building, looking over the edge at the ground below and the reinforced wall facing them about fifteen meters away. "He's got to be kidding," Halloran murmured at Jonny's side.

Jonny nodded wordlessly, his eyes shifting to Bai as the instructor finished his verbal description of the maneuver and stepped to the edge to demonstrate. "As always," Bai said, "you start with a targeting lock to give your computer the range. Then you just... jump."

His legs straightened convulsively, and an instant later he was arcing toward the facing wall. He hit it feet first about five meters down, his shoes scraping loudly as they slid a short distance further down along it. The combination of that friction plus the impact-absorbing bending of his knees flipped him partly over; and when his legs straightened again an instant later, the push sent him back toward the original building in a heels-over-head flip that somehow managed to have him feet forward when he struck the side, another five meters closer to the ground. Again he shoved off, and with one final bounce-and-flip off the far wall, he landed safely on the ground at the base of their building. "Nothing to it," his voice drifted up to the waiting trainees. "I'll be up in a minute, then we'll all try it."

He disappeared inside. "I think I'd rather take my chances with a straight jump," Noffke said to no one in particular.

"That's fine for a five-story building, but you'd never make it with anything really tall," Deutsch shook his head. "We do have some real cities on Adirondack, you know."

"I'll bet the Great Horizon Hope could give you a dozen more reasons why this is a good maneuver," Viljo put in, smiling sardonically at Jonny.

"Would you settle for two?" Jonny asked calmly. "One: you're never in free fall for very long this way, and besides making for a softer landing that'll play havoc with any manual or autotarget weapon they try shooting at you. And two: with your legs pointing up most of the time, your antiarmor laser's in good position to fire at whatever you were escaping from on the roof."

He had the satisfaction of seeing some of the other trainees nodding in agreement, and of watching Viljo's smirk sour into a grimace.

There was more—much more—and for ten days Bai put them through their paces. Gradually, the daily computer modules began to remove the restraints set onto their most dangerous equipment; just as gradually, the scorch-lasers and dye-pellets used by their metallic opponents were replaced by genuine weapons. Half a dozen of the trainees picked up minor burns and pellet wounds, and a new seriousness began to pervade the general attitude. Only Deutsch retained his bantering manner, and Jonny suspected it was simply because he was already as serious beneath the facade as the man could possibly be. The evening lectures were replaced by extra training sessions, giving them the chance to practice with their enhanced night vision the techniques they had so far used only in daylight and dusk. All of it seemed to be building to a head... and then, almost unexpectedly—though they all knew the schedule—it was over.
