"Your brother. You see, I need to try to develop antibodies to the telomerase enzyme that won't be rejected by his immune system. I think there's an outside chance that I could culture antibodies taken from someone with the same blood type and use them to arrest the rampant multiplying of telomerase enzyme about to begin in Bartlett's blood."

"I'm here because you're using me!" She couldn't believe her ears. And Grant had set it up. No wonder he was finally feeling guilty.

"I just need to borrow your immune system for a few days. It's very safe."

"I don't think so. I'm out of here."

"Actually, the procedure is already under way. While Debra was taking your last blood sample, she also injected a minuscule amount of the telomerase enzyme in active form, the proprietary version used in the Beta, into your bloodstream. Don't worry. It's perfectly safe. The dosage was so minute that there's no way it could have any effect on you."

"You have got to be kidding!" My God, she thought, I could sue the hell out of—

"Don't worry, think of it like a smallpox vaccination." He paused. "Now, though, I have to tell you that I just learned the initial dosage probably didn't do the trick. The amount of antibodies created was, unfortunately, minuscule. Which means we need to go to a slightly higher infusion. But again, don't worry. It's still safe."

"I can't believe I'm hearing this," she said finally, gasping for air in her fury. "You didn't ask—"

"Alexa," he cut in, "right now I have something like two weeks left to try to head off the Syndrome in Winston Bartlett. If we achieve that, then I'm hopeful the antibodies he creates can be successfully used to start reversing the Syndrome in Kristen. We will know how to manage the Beta. Who knows where that could lead? But it all begins with you. You're the clean slate we need to start."

"Before we go one step further, I want to know what, exactly, happens with the Syndrome. I think I know, but I'd like to hear—"
