"And you couldn't block them out?"
"No. In fact they're in my head right now."
Her words were a cold knife between Jack's shoulder blades.
"You mean they're here, listening to us?"
Kate's expression was bleak as she nodded. "Through me. And trying to keep me from telling you all this."
Revulsion stirred and crawled through Jack's gut as he tried to imagine the horror of what that would be like. He couldn't. His mind… invaded, violated, raped, and dominated… unimaginable.
"But Kate… you were never sick."
"That's because my immune system is like everyone else's, I guess. This virus can slip past the perimeter defenses and take control before it has time to react. But not in your case."
"What's so special about me?"
"That's what I'd like to know. Because…" With knitted brows Kate stopped and turned her head, as if listening.
"Something wrong?"
"The pressure just let up."
"What pressure?"
"The pressure to silence me… it's gone." Her eyes widened. "The Unity wants the answer too. You beat the virus, Jack."
"How do you know it wasn't some other virus I picked up—a summer flu or the like?"
"Oh, the Unity knows, Jack. Believe me, it knows. And it's afraid of you. You're a wild card, an aberration, an unexpected glitch in their master plan. Maybe you shouldn't say anything."
"Listen, we're related, so if I've got something inside me that can fight this, maybe you do too. You want to test my blood, it's yours."
"I don't have the equipment or the knowledge, but NIH and CDC do—you'll be invaluable to them. But the why still remains. Immune systems react to invading substances like viruses and attack them. It's a 'me' / 'not-me' reaction. Anything classified as 'not-me' must go."
"I like that."
"Sometimes it can overreact to innocent things like pollen, resulting in allergies, but the basic xenophobic protocol never changes. Viruses like HIV get past by invading the immune cells themselves, eventually destroying them; but this is ultimately bad for the virus since it then leaves the host open to every infectious organism that comes along. The Unity virus has a more practical approach: co-opt the immune system and leave it intact to function against everything but the Unity virus. That's what it did to me."
Jack squeezed his eyes shut. Aw, Kate. I can't stand this.
He said, "Why not me then?"
"I can't say. I can only guess that sometime in the past your immune system has battled something similar to, but not exactly like, the Unity virus."
"Why do you qualify it?"
"Because if you'd fought off something exactly like it before, you'd be fully immune and your system would have wiped out the virus as soon as it entered. Remember when you had chickenpox as a kid? The infection left you with permanent immunity: cellular guns loaded with varicella-seeking bullets. Should you get too close to a poxy kid and pick up some of the varicella virus, it's gobbled up the instant it hits your bloodstream, without your having an inkling it was there at all."
"But I got sick as a dog, so that means my guns were not loaded for the Unity virus."
"Right. But unlike my immune system, yours got put on alert by something about the Unity virus. My guess is a minor antigenic similarity. Maybe because of a previous infection, it recognized just one or two base sequences in its protein coat; whatever it was was enough to trigger an immune response, and your T-cells declared war."
Love those T-cells, Jack thought, but why should mine be special?
"The thing is, Kate, I'm almost never sick. I don't even get the usual infections, let alone special ones."
"Gia told me you were terribly ill last summer—just as sick as you were yesterday."
"Oh, that. That wasn't a bug I caught, that was from some infected wounds."
"Wounds?" Kate's brow furrowed. "Who wounded you?"
Jack was about to say, Not who—what, when it all came together, whipping his head around like a backhanded bitchslap.
"Holy shit!"
"What?"
How could he tell her about the creatures that had almost killed him last August, about how the gouges one of them had torn across his chest became infected, leaving him fevered up for days after? If some contaminant from those things had primed his immune system, allowing it to recognize the Unity virus, then that meant the virus was linked to them.
Was the same power responsible for those creatures also behind the virus? Was that what was going on here? He needed more information but didn't know where to find it.
"Jack, what's wrong?"
Could he tell her? Nope. His story was even more fantastic than hers. Sound like he was playing Can You Top This? And how could he explain what he didn't understand himself? All he knew was that they were dealing with pure evil.
Used to be Jack didn't believe in evil as an entity. But he'd come to know it was out there—no belief necessary, he'd experienced it—and very real, very hungry.
He pressed the heels of his palms against his eyes but it didn't slow his spinning mind. Couldn't worry about the big picture now. Had to stay focused on Kate and what was infecting her.
"Just a splitting headache," he lied.
"You were going to tell me about some wounds."
"There were nothing special."
"You don't know that. Something—"
"Please, Kate, we can worry about that later—"
"But I'm worried about it now, Jack!" she said and he saw tears filling her eyes. "I don't want to die."
"You're not going to die."
"Yes, I am! What's me, who I am…" She tapped her right temple as the tears spilled down her cheeks. "I'm dying in there, being eaten alive neuron by neuron. Soon I'll be gone, Jack, and I don't want to go. I've got too much left to do!"
Kate seemed to shrink, looking more like a frightened little girl than a professional and mother of two, and Jack's heart broke for her.
He struggled from the recliner. The effort, along with the change in position, made the room spin but he clenched his teeth and held on.
He dropped to his knees before his sister and put his arms around her, enfolding her in his blanket. She was trembling like a wounded thing.
He whispered in her ear. "I swear to you, Kate, that's not going to happen. I won't allow it."
"You don't know that. You can't say that."
"Yes, I can."
A cold resolve had taken shape within him, and Jack knew now what he had to do.
He waited till she'd composed herself, then sat back on his haunches, looking up at her.
"First we need to gather our facts. How many people in this Unity now—not including you?"
"Eight."
"Do you know their names and where they live?"
"No, I—" And then she stopped and cocked her head again. "I'll be darned. I do know."
"Great. Write them down and—"
"Why?" she said sharply. "So you can track them down and shoot them?"
Her words rocked him. "What makes you think I'd do something like that?"
"I found your guns, Jack."
Damn.
"That doesn't mean I'm planning to go out and shoot them."
But that was what was running through his head. Jack rarely believed in following the shortest course between two points, but with Kate at risk, the rules changed. He figured with Holdstock and the others dead there'd be no ubermind to control her. As the only surviving infected brain, Kate could remain Kate.
He hoped.
"Don't lie to me, Jack. And I don't know how you can even consider such a thing. They're not evil."
"Tell that to Fielding."
