“Prisoners,” said Dr. Abbey.

“They volunteered,” said Kelly, a stubborn note in her voice. “Yes, they were prisoners. They had no chance of parole, no chance of ever being released back into the public, and use of human test subjects has a… it has a long and time-honored place in medical science. Sometimes it’s the only thing you can do. That’s how they discovered that yellow fever was spread by mosquitoes, you know. How… how they proved that smallpox inoculation worked. A lot of people’s lives were saved by human testing. When there wasn’t any other choice. When there wasn’t any other way.”

“How many lives did this save?” asked Dr. Abbey.

“What did you do?” asked Alaric.

His was the question Kelly chose to answer. Darting a glance toward him, she said, “The choice was offered to certain inmates whose viral profile matched the criteria. Let us inject them with a potential vaccine and, if they recovered, we’d enter them in the witness-protection program. Whole new identities. Whole new lives. They could start over.”

“If they lived,” said Alaric, softly.

Kelly winced.

“Come on, princess,” said Becks. “Story hour isn’t over yet. I want to know what happens next.”

“The volunteers were injected with a serum containing deactivated viral particles from the opposing strain. The theory was that maybe one strain would destroy the other. Best-case scenario, they’d both destroy the other, and we’d finally have a treatment. Worst-case scenario…” Her voice tapered off.

Dr. Abbey took up the thread when it became clear that Kelly wasn’t going to, saying, “Worst-case scenario is what they got. Not only did every single one of their ‘volunteers’ go into spontaneous amplification when the two strains met, but they bred a new strain—one that increased mob behavior in exposed infected. They fucked up gloriously. And then they swept it all under the rug, with the rest of their failures.”

“What did you want us to do?” Kelly’s head snapped up, eyes narrowing as she glared at Dr. Abbey. “Did you want us to just sit back and watch the virus do its thing, not even try to find the answer? Yes, people died. Yes, mistakes were made, and mistakes will be made, and someday, maybe, because of those mistakes, we’ll have a cure. Wouldn’t you like that? A cure? An end to all the fear? Because that seems like a really good thing to me, and if I have to work with the CDC to make it happen, that’s what I’m going to do.”
