Mere seconds later the computer offered a list of various electrolytes and glucose molecules and other little bits in the blood; it would take longer for a full analysis, calculating what, for example, the glucose density suggested about his liver health, but the computer would update those details as it went. The next set of notes to appear were genetic modifications; they had been so common before the Break that almost everyone on the island had at least a few. Marcus had the genetic markers for in vitro gene correction, meaning his parents had scrubbed his DNA for congenital diseases before he was even born. He had another marker in his red blood cells, signifying some sort of bone marrow modification, but neither Kira nor the computer could tell exactly what it was without a full bone sample. It didn’t matter either way; Skousen and the other researchers had already examined the gene mods as a possible source of RM immunity, but it was a dead end—if anything, it seemed to make the subjects more vulnerable to the virus, not less. Kira moved on and started taking 3-D photos of the blood, examining individual portions of it for anomalies, when the computer chirped a small alert, and a glowing blue rhombus appeared in the corner of the screen. She frowned, glancing at Marcus, but he only shrugged and shook his head. She looked back at the screen and tapped the alert.
A new section expanded across the screen, one brief sentence with a handful of pictures attached:
“What?” Kira whispered. The number blinked, updating to twenty-eight. She tapped one of the pictures, and it flew up into a corner of the screen, enlarging to a 3-D representation of RM. It was a rough, fat sphere, highlighted in yellow to stand out from the background image. It looked putrid and menacing.
The number in the alert continued to grow:
“This virus is everywhere,” said Kira, flicking through the images almost as fast as they popped up. She’d seen the structure of the virus before, of course, as part of her early medical studies, but never like this. Never so much of it, and never in a live human. “This can’t be right.”
“I’m not sick, obviously,” said Marcus.
Kira frowned, and studied one of the images more closely. The virus loomed over the other data like a predator, vast and insatiable. “It’s not telling me this is abnormal,” said Kira, “it’s just telling me it’s there. Someone told the computer how to recognize the virus, but didn’t tell it the virus was a cause for concern. How common is it?” She looked back at the alert and saw a small link to the database. She tapped it, and a new box appeared, a long, thin rectangle down the full right side of the screen. When she expanded it, she found it was a list of similar references. She sifted through it with her finger, pulling up page after page of links. She clicked one, and found another patient’s file, their blood filled with RM. She looked at another and another, all the same. She almost didn’t dare to say it out loud.
“We’re all carriers,” she said. “Every single survivor has it in us, all the time. Even if we’re resistant to it, we can still pass it along. That’s why the babies die—that’s why it gets them so fast. Even in an airtight room.” She looked up at Marcus. “We can never get away from it.” She sifted through the images of the virus, trying to remember everything she’d learned about how it spread and functioned. Part of RM’s danger was that it didn’t behave like a normal blood-borne virus—it lived in the blood, yes, but it lived in every other part of the body as well; it could be passed through blood, saliva, sex, and even the air. Kira pored over the images, looking at the structure of the virus, looking for anything that would key her in to the secret. It was a big virus, big enough to contain every function of a very complex system—though they still didn’t know exactly what that system was.
Marcus rubbed his eyes, dragging his hands slowly down his face.
“It’s what I told you before—the top minds left in the world have been studying RM for eleven years. They’ve looked at everything.”
“But there has to be something else,” said Kira, flipping furiously through the list.
“Live studies, dead studies, blood scrubbers, dialysis, breath masks. There are even animal studies in here. Kira, they’ve studied literally everything they could possibly get their hands on.”
She kept flipping through study after study, variable after variable. And as she reached the end of the list, something dawned on her.
There was one test subject not included anywhere in the database. A subject no one had seen in eleven years.
Kira paused, staring at the screen, feeling dirty and uncomfortable as the virus stared darkly back.
If they wanted to understand that virus, why not go to the source? If they wanted to see what true immunity looked like, why not look at the subjects who were truly immune?
