"Why wouldn't you cure it?" I asked. "If you can 'shore up' an affected region, it sounds like you could probably fix it completely if you wanted to."

"We can, but it's not necessary," Dr. Russell said. "You'll be getting a more comprehensive overhaul in a couple of days. We just need to keep you going until then."

"What does 'comprehensive overhaul' mean, anyway?" I said.

"It means that when it's done, you'll wonder why you ever worried about a spot of cancer on your testicle," he said. "That's a promise. Now, there's one more thing we need to do here. Bring your head forward, please."

I did. Dr. Russell reached up and brought the feared arm cup down directly on the top of my head. "During the next couple of days, it's going to be important for us to get a good picture of your brain activity," he said, moving back. "So to do this, I'm going to implant a sensor array into your skull." As he said this, he tapped the screen on his PDA, an action I was learning to mistrust. There was a slight sucking noise as the cup adhered to my skull.

"How do you do that?" I asked.

"Well, right now, you can probably feel a little tickle on your scalp and down the back of your neck," Dr. Russell said, and I could. "Those are the injectors positioning themselves. They're like little hypodermic needles that will insert the sensors. The sensors themselves are very small, but there's a lot of them. About twenty thousand, more or less. Don't worry, they're self-sterilizing."

"Is this going to hurt?" I asked.

"Not so much," he said, and tapped his PDA screen. Twenty thousand microsensors slammed themselves into my skull like four ax handles simultaneously whacking my skull.

"God damn it!" I grabbed my head, banging my hands against the crèche door as I did so. "You son of a bitch," I yelled at Dr. Russell. "You said it wouldn't hurt!"

"I said 'not so much,'" Dr. Russell said.

"Not so much as what? Having your head stepped on by an elephant?"

"Not so much as when the sensors connect to each other," Dr. Russell said. "The good news is that as soon as they're connected, the pain stops. Now hold still, this will only take a minute." He tapped the PDA again. Eighty thousand needles shot out in every direction in my skull.

I have never wanted to punch a doctor so much in my life.

"I don't know," Harry was saying. "I think it's an interesting look." And with this, Harry rubbed his head, which like all our heads was now a dusty speckled gray where twenty thousand subcutaneous sensors sat, measuring brain activity.

The breakfast crew had reconvened again at lunchtime, this time with Jesse and her roommate Maggie joining the crowd. Harry had declared that we now constituted an official clique, branded us the "Old Farts," and demanded we begin a food fight with the next table over. He was voted down, in no small part due to Thomas noting that any food we threw we wouldn't get to eat, and lunch was even better than breakfast, if that was possible.

"And a damned good thing, too," Thomas said. "After this morning's little brain injection, I was almost too pissed off to eat."

"I can't imagine that," Susan said.

"Notice how I said 'almost,'" Thomas said. "But I'll tell you what. I wish I'd had one of those crèches back home. Would have cut my appointment times by eighty percent. More time for golfing."

"Your devotion to your patients is overwhelming," Jesse said.

"Fah," Thomas said. "I played golf with most of them. They would have been all for it. And as much as it pains me to say it, it helped my doctor make a much better assessment than I ever could have. That thing is a diagnostician's dream. It caught a microscopic tumor on my pancreas. There's no way I could have caught that back home until it was a hell of a lot larger or a patient started showing symptoms. Did anyone else have anything surprising?"

"Lung cancer," Harry said. "Little spots."

"Ovarian cysts," Jesse said. Maggie seconded.

"Incipient rheumatoid arthritis," said Alan.

"Testicular cancer," I said.

Every man at the table winced. "Ouch," said Thomas.

"They tell me I'll live," I said.

"You'll just be lopsided when you walk," said Susan.

"That's enough of that," I said.

"What I don't understand is why they didn't fix the problems," Jesse said. "My doctor showed me a cyst the size of a gumball, but told me not to concern myself with it. I don't think I'm cut out not to worry about something like that."

"Thomas, you're alleged to be a doctor," Susan said, and tapped her gray-shaded brow. "What's with these little bastards? Why not just give us a brain scan?"

"If I had to guess, which I do, since I really have no clue," Thomas said, "I'd say that they want to see our brains in action while we go through our training. But they can't do that with us strapped to a machine, so they're strapping the machines to us instead."

"Thanks for the cogent explanation of what I already figured out," Susan said. "What I'm asking is, what purpose does that sort of measurement serve?"

"I dunno," Thomas said. "Maybe they're fitting us for new brains after all. Or maybe they've got some way of adding new brain material, and they need to see what parts of our brains need a boost. I just hope they don't need to put in another set of the damned things. The first set nearly killed me from the pain."

"Speaking of which," Alan said, turning to me, "I hear you lost your roommate this morning. Are you okay?"

"I'm all right," I said. "Though it's depressing. My doctor said that if he had managed to make it to his appointment this morning, they probably could have kept him from dying. Given him a plaque remover or something. I feel like I should have made him get up for breakfast. That might have kept him moving long enough to make it to his appointment."

"Don't kick yourself about it," Thomas said. "There's no way you could have known. People just die."

"Sure, but not days from getting a 'comprehensive overhaul,' as my doctor was putting it."

Harry piped in. "Not to be too crass about this—"

"You just know this is going to be bad," Susan said.

"—but when I went to college," Harry continued, throwing a piece of bread at Susan, "if your roommate died, you were usually allowed to skip your finals for that semester. You know, because of the trauma."

"And oddly enough, your roommate got to skip them, too," Susan said. "For much the same reason."

"I never thought of it that way," Harry said. "Anyway, think they might let you sit out the evaluations they have planned for today?"

"I doubt it," I said. "Even if they did, I wouldn't take up the offer. What else would I do, sit in my stateroom all day? Talk about depressing. Someone died there, you know."

"You could always move," Jesse said. "Maybe someone else's roommate died, too."

"There's a morbid thought," I said. "And anyway, I don't want to move. I'm sorry Leon's dead, of course. But now I have a room to myself."

"Looks like the healing process has begun," Alan said.

"I'm just trying to move past the pain," I said.

"You don't talk much, do you," Susan said to Maggie, rather suddenly.

"No," Maggie said.

"Hey, what does everyone have next on their schedule?" Jesse asked.

Everyone reached for their PDA, then stopped, guiltily.

"Let's think about just how high school that last moment really was," Susan said.

"Well, hell," Harry said, and pulled out his PDA anyway. "We've already joined a lunchroom clique. Might as well go all the way."

It turned out Harry and I had our first evaluation session together. We were directed to a conference room where chairs with desks had been set up.

"Holy crap," Harry said as we took our seats. "We really are back in high school."
