Not this time, but it had happened.

"You... bastards," Carey said. Panting, he flung his rifle down on the ground. Pitiful in his nakedness, he had clearly wet himself, but was unconscious of it.

"You incredible bastards." He took another breath, and held it. This was a critical moment. He looked back at the grendel. Justin remembered the first time they had done this, and what the kid had said afterward. There had been no one to do this for him-he was one of the eldest Star Born, and no Earth Born even dreamed that something like the Grendel Run was going on. None of the Earth Born would do something so risky... and so much fun.

But he knew that Carey was looking at them. And the rifles, and then at the grendel. And remembering the incredibly short pause before the grendel was blown back into the water. Less than a second. Time enough to lose control of his bladder. Time enough to feel more naked and defenseless than he had ever imagined a human being could feel. Time enough to experience the incredible precision required by a kill team.

Carey looked at them and swallowed. He knew somehow that his entire reputation for machismo rested upon what he said next.

"Well..." He strained to sound casual. He bent, picked up his rifle. He walked toward them until he was standing three feet from Justin. He extended the rifle with his left hand. Justin extended his own right to take it-and Carey hit him, quite hard and very quickly, with his right fist, just under the left ear.

Justin stumbled back, tripped, and went down.

Finally Carey smiled. "That was... pretty fair shooting." He watched Justin carefully.

Justin pushed himself up to a sitting position. He felt his jaw tenderly. "Got a pretty good right there, kid." And held up his hand.

Carey took it and yanked him up, then stood with his legs slightly apart, well balanced. His lopsided grin was challenging. "Hendrick's a good coach," he said. Justin nodded. No action. A great sigh seemed to go through them all, a release of tension.

"You'd have got him, you know," Justin said. "It was a good hit."

"Why the hell do you do that?" Carey asked.

"It's fun," Aaron said.

Justin frowned. "We had a kid panic once. Nobody got shot, but it was close."

"Why paint? Cassandra would know if I hit—oh."

"Heh. Cassandra doesn't know about this. Jesus, can you imagine what Zack would do?"

They all laughed.

"So who panicked?"

Justin looked at him and shook his head.

"Edgar," Aaron said.

Carey smiled knowingly.

"Got the grendel, though," Justin said.

Carey coughed politely. "Who's got my clothes? My nuts are freezing."

Heather sashayed out of the dark. "Here's a blanket," she said sweetly. The blanket was wrapped around her. When she opened it, there was nothing underneath but Heather.

Carey swallowed hard. It wasn't certain, but the good bet was that Carey was still a virgin. Well, this evening would see the end of that onerous burden.

Heather wrapped the blanket around the both of them, and Carey became very, very involved in a kiss. Amid the general cheering, the two of them retreated from the firelight.

Aaron grinned. "Today I am a man," he said.

"Indeed. Now. Jessica-any other ghoulies about?"

"No grendel-sized heat sources. Let's harvest some samlon."

By the time they got back to Heorot, Tau Ceti was rising over the mountains.

Mercifully, the day was set for lazing and play. Carey Lou managed to stagger to his tent and collapse. Or at least they assumed that he was collapsing. Heather was with him, and the more Justin thought about it, the more he was convinced that a fourteen-year-old libido just might be impervious to fatigue, fear, and a thorough workout by the (rumor had it) inexhaustible Miss McKennie.

Ah, youth.

The day passed quickly, samples were gathered and catalogued, lessons on wildlife and herbology were taught by the elder Scouts, and a considerable amount of skinny-dipping, impromptu tree-climbing competitions, and general hell-raising continued through the day.

When evening finally fell again, there was a pleasant air of fatigue settling over the camp. They had shared two extremely alive days. Carey had also learned that three other Biters had suffered as he had. He was a member of a fraternity now, and he was already relishing the thought of passing that favor to one of the younger kids in a few years. Say, his younger brother Patrick...

The cook fires were burning, and soon dinner would be prepared. But there was another question still on the Biters' minds, and they had pestered their elders all day long.

Finally, Aaron sat them down, not a shred of playfulness in his attitude.

"All right," he said. "There's something serious we need to talk about tonight. Tonight, it's time that you learned things."

"About our parents?" Sharon asked.

"Things about your parents. And grandparents. There are reasons why they didn't come over here. Why we're the ones."

"Why?"

Justin and Jessica looked at each other nervously; then Justin said, "When you freeze something that has water in it, you get ice crystals. They thought that they had whipped the problems, but something went wrong. They froze the crew of Geographic. They woke them up in shifts for various duties around the ship, crossing from Sol to Tau Ceti. And there were problems."

"Problems?" Carey asked.

"Yes. When you freeze people for a hundred years and then wake them up, chances are you've formed some ice crystals in their brains. Wake them twice, you get more crystals. Crystals rupture cells, mess it up in-" He tapped his skull. "-here."

"What did it do?"

"A lot of our parents aren't as smart as they used to be. They get emotional problems, too. Coordination. Early strokes. Just plain stupidity. At first it didn't really matter. They were still smarter than most people they'd known, and they'd chosen the island because it was safe. No problems to face, nothing they couldn't deal with. Even then, they got in the habit of talking things over, being sure they weren't doing something stupid-"

"Rules," Sharon McAndrews said.

"Rules," Justin agreed. "And that was good enough for a while. There weren't any real dangers here, none that they knew about anyway. Then, the first grendel came. They didn't understand. They had rules, and they stuck to the rules, and it didn't work, but Colonel Weyland helped them and they defeated the first grendels. They went hunting, and when they thought they had killed all the grendels, they hadn't. You know about that. What you don't know is how bad it shook them. After the Grendel Wars they stopped trusting themselves and they stopped trusting each other. They didn't work well together when the grendels popped up, and that's one of the reasons that our parents are so afraid of them now."

There was silence. Justin could see it: they were trying to find a lie in the story. But there were too many clues. They knew, they had always known. There was something wrong with Mom, with Dad. With Uncle. They had always known, but never had a label.

Now they did.

"Ice on his mind," Carey Lou said. "I've heard that, but nobody would tell me what it meant-"

"And my mother slapped me when I said it to her," Sharon said.

"Christ," Carey Lou said. "What can we do?"

"Love them," Jessica said. "They're doing the best they can. That's what we expect of you. Just love them, but do your own thinking. Including about their rules. That's why they make rules. They don't trust their own thoughts, not when they act alone. So they try to get a collective judgment on everything that can happen, and make that a rule, and then they follow the rules no matter what."

"Ice on their minds," Carey Lou said again, slowly. "Son of a bitch!"
