"A Tattoo"

"The virus really has no cure?" Marietta held her breath, trying to see whether Paul was lying or not, but Paul obediently shook his head. 

"There's no cure. But there's a vaccine...our troops are already vaccinated. Of course, the vaccine won't work for those who are already infected." 

When Ainsley heard this, she almost wanted to kill Paul right away. 

No cure, and the vaccines only worked for those who weren't infected yet. That's not really helpful, isn't it? Not to mention she didn't know how to get the vaccines! 

Say, in the worst-case scenario...all fifty virus carriers managed to inject the virus into fifty members of the Sloan Family. 

Then, even if they managed to isolate the victims based on unconscious ones an hour ago, there would still be more than fifty people, and those fifty could infect the rest of the suspects…

The casualties rate would be high. But it couldn't be helped.
