“In the interest of”—Morgan paused, as if searching for the right way to say it—“a peaceful working relationship, I will be more communicative.” She tapped a few icons on the wall screen, which split into three sections—the line diagram of Kira’s body on one side, and two half-size boxes on the other showing two sets of data: one labeled “Expiration” and one labeled “Kira Walker.” “Dr. Vale and I were part of the Trust—the group of ParaGen scientists who created the Partials and the RM plague. We didn’t intend for the plague to bring the human race to the brink of extinction, obviously, but the damage is done, and once I realized the humans were a lost cause, I turned my attention to the Partials instead. I’ve spent the last twelve years helping them build a new civilization, trying to find ways to overcome the sterility and other handicaps hardwired into their DNA. Imagine my surprise when they began dying, for no discernible reason, precisely twenty years after they were created.”

Vale spoke up again. “The expiration date was—”

“The expiration date was the surest sign that ‘the Trust’ was a horrible misnomer,” said Morgan. “Living, thinking beings that I helped create were preprogrammed to wither to dust in a matter of hours the moment they hit their biological deadline, and I knew nothing about it. I’ve been doing everything in my power to fix it, which brings us here.”

“You think I can cure it,” said Kira.

“I think something in your body holds the secret that will help me cure it,” said Morgan. “The last time I had you in a lab, when we discovered you were a Partial—another secret the ‘Trust’ kept from me—my initial scans determined that despite being a Partial, you had none of the genetic handicaps the others have: no sterility, no fixed age, no inhibition of growth or any other human function. If it turns out that you have no expiration date either, there might be a way to reverse engineer certain fragments of your genetic code to help save the rest of the Partials.”

“I’ve already told you that this is impossible,” said Vale. “I’m the one who programmed the expiration date—I’m sorry I couldn’t tell you at the time, but there it is. You were unstable, and no, we didn’t trust you. It wasn’t just you, though—Armin didn’t trust me with some of the pieces, either.”
