But because every day is exactly the same, it should have been the first thing I noticed—the very first, given the bright red vests they’re wearing. The uniforms beneath them are dark, smoky gray—not the black of the PSFs. The pads of my fingers sting just looking at them—it’d been so hard to get the plastic needle through the thick fabric I’d pricked myself enough times to draw blood. Three months ago, we’d sewn buttons on them, as well as patches of numbers across the breast pockets. I’d thought nothing of it at the time. We’d dyed and stenciled any number of prison uniforms, so I’d just assumed...I just thought we’d never see them again.

Beside me, Vanessa manages to cut off her gasp but can’t get her body’s instinctive response under control. To our PSF’s satisfaction, she flinches and looks away quickly, like the sight of the Red alone could burn her.

I don’t need to look around me to know that at least half of our cabin has already figured out what’s happening. Those same girls have already moved on to drawing further conclusions that will take me another week to puzzle out. For all our differences, our Green minds really only function in two ways—my way, the storage locker, or their way—the ability to connect multiple dots of a situation or problem as easily and quickly as breathing. I get the impression we bore them every time we try to talk to them, like they always know what we’re about to say next. In a fraction of a second, they can look at Vanessa’s reaction, see how young the new people are, assess the color of the vest, recognize the uniforms we helped stitch together, and recognize now, in context, that the frustrating number patches were really Psi identification numbers. I can practically feel their minds churning behind me, whipping up a frenzied series of thoughts. Reds.

If I know them, those girls will be thinking ahead, their conclusions slanting toward the future. Why are they here? How will it affect me? When will they leave? But I’m trapped in the past. Do the other girls remember, the way I do, the faces under the caps they wear? They’re blank, so completely vacant that it looks like their features have been painted on their skin.

My stomach begins to turn over itself, the burning taste of sick rising in my throat like acid. How? How did they do this to these kids? I know the first face that we pass along the way to the Mess Hall; I know that girl because she was at this camp. She was here for almost two years before they took the Reds and Oranges out that night. I don’t forget faces, and even though I’d tried cutting the memories up and storing them in a dark, locked place, I can feel them bubbling back up, trying to merge together again. Fires in the cabins. Fires in the Mess Hall. Fires in the wash houses. The sky stained black with smoke. The boy who tried running from the Garden, who fried himself against the fence when his fire couldn’t melt the metal fast enough. That winter, that whole winter, we’d gone without real vegetables and fruit because the only things he’d set on fire that day were our food and himself.

The thing about the Reds was this: no matter how still they were, watching them was like having eyes on a pot of water set to simmer. A small uptick in temperature could set them to boil—it could happen that fast, in a second of carelessness. They were the monsters of our stories, ones who couldn’t bring themselves to lurk in the shadows. And as terrifying as they were, as little as they cared about the rest of us, I never felt so defeated as I did when the camp controllers removed them. Because even if the rest of us were pathetic and too scared to even make eye contact, they were always pushing back, they were always fighting, they never fell into the pattern.

I thought they’d killed them. We all did.

My feet get sucked down into Thurmond’s dark mud; I can’t even feel the cold anymore; panic heats my blood and makes my hands jitter at my side uselessly.

They hold no weapons that I can see—no guns, or knives, or even the handheld White Noise machines. I guess that makes sense. They’re the weapons themselves.

What have they done to them? How easy would it be for them to do it to the rest of us?

I count twenty along the way to the Mess Hall, spaced out evenly, filling in the gaps where there used to be PSFs. Where there are black uniforms, they’re hanging back off the trails, watching us pass by in clusters, talking to each other and smiling, actually smiling about it, the sickos.

It feels like a challenge—like they want to see us shrivel up just that little bit more when we see how helpless we really are. Just when you become numb to the cold running bony fingers up and down your bare skin, when your muscles become too used to the punishing schedule of go, go, go, go, work, work, work, work, when you realize it’s possible to turn a deaf ear on hateful words—that’s when the men up in their Tower know they need to change the rules of whatever game they’re playing with us.

Vanessa keeps trying to catch my attention; I see her nodding toward each Red we pass, as if I could somehow miss that they’re there. The sleet has turned back into rain, and before we get within a hundred feet of the Mess, we’re all drenched, the icy water slicing through our clothes and skin, down to our bones. I can’t give the PSFs the pleasure of seeing me look at each of the Reds. I try to watch them out of the corner of my eye, assessing each face. I recognize about half of them; that makes sense. There just weren’t that many Reds at Thurmond to begin with, and even back then, they tried to keep boys and girls separate at meals and the different work rotations. It was harder to cross paths with them, and it takes me a little longer to dig around for the right memories, but I have them. My eyes shift again, assessing what’s ahead as we come up on the Mess Hall. And then—
