I came to find you last night," Lena says more quietly. "When I knew there was going to be a raid...I snuck out. I was there when—when the regulators came. I barely made it out. Alex helped me. We hid in a shed until they were gone..."
I close my eyes and reopen them. I remember wiggling into the damp earth, bumping my hip against the window. I remember standing, and seeing the dark forms of bodies lying like shadows in the grass, and the sharp geometry of a small she shed, nestled in the trees.
Lena was there. It was almost unimaginable.
"I can't believe that. I can't believe you snuck out during a raid—for me." My throat feels thick again, and I will myself not to start crying. For a moment I am overwhelmed by a feeling so huge and strange, I have no name for it: It surges over the guilt and the shock and the envy; it plunges a hand into the deepest part of myself and roots me to Lena.

It’s for the best. But no matter how many times I repeat it, the strange, hollow feeling in my stomach doesn’t go away. And ridiculous as it is, I can’t shake the persistent, needling feeling that I’ve forgotten something, or missed something, or lost something forever.

Hana?" Lena says softly. "Are you okay?"
That single stupid question breaks me. All the metal fingers relax me at once, and the tears they've been holding back come surging up at once. Suddenly I am sobbing and telling her everything: about the raid, and the dogs, and the sounds of skulls cracking underneath regulator's nightsticks. Thinking about it again makes me feel like I might puke. At a certain point, Lena puts her arms around me and starts murmuring things into my hair. I don't even know what she's saying, and I don't care. JUst having her here—solid, real, on my side—makes me feel better than I have in weeks. Slowly I manage to stop crying, swallowing back the hiccups and sobs that are still running through me. I try to tell her that I've missed her, and that I've been stupid and wrong, but my voice is muffled and thick

Then someone knocks on the door, very clearly, four times. I pull away from Lena quickly.
"What's that?" I say, dragging my forearm across my eyes, trying to get control of myself. Lena tries to pass it off as though she hadn't heard. Her face has gone white, her eyes wide and terrified. When the knocking starts up again, she doesn't move, just stays frozen where she is.
"I thought nobody comes in this way." I cross my arms, watching Lena narrowly. There's a suspicious needling, pricking at some corner of my mind, but I can't quite focus on it.
"They don't. I mean—sometimes—I mean, the delivery guys—"
As she stammers excuses, the door opens, and he pokes his head in—the boy from the day Lena and I jumped the gate at the lab complex, just after we had our evaluations. His eyes land on me and he, too, freezes.
At first I think there must be a mistake. He must have knocked on the wrong door. Lena will yell at him now, tell him to clear off. But then my mind grinds slowly into gear and I realize that no, he has just called Lena's name. This was obviously planned.

I’m used to a feeling of doubleness, of thinking one thing and having to do another, a constant tug-of-war. But somehow Hana has fallen cleanly away into the double half, the other world, the world of unmentionable thoughts and things and people.

Is it possible that all this time I’ve been living my life, studying for tests, taking long runs with Hana—and this other world has just existed, running alongside and underneath mine, alive, ready to sneak out of the shadows and the alleyways as soon as the sun goes down? Illegal parties, unapproved music, people touching one another with no fear of the disease, with no fear for themselves.

A world without fear. Impossible.

And even though I’m standing in the middle of the biggest crowd I’ve ever seen in my life, I suddenly feel very alone.

I want to apologize to you,” she says calmly.
“Oh yeah? For what?” I don’t have time for this. We don’t have time for this. I push away thoughts of what will happen to Hana even if I manage to escape. She’ll be here, in the house . . .
My stomach is clenching and unclenching. I’m worried the bread will come straight back up. I have to stay focused. What happens to Hana isn’t my concern, and it isn’t my fault, either.
“For telling the regulators about 37 Brooks,” she says. “For telling them about you and Alex.”
Just like that, my brain powers down. “What?"
“I told them.” She lets out a tiny exhalation, as though saying the words has given her relief. “I’m sorry. I was jealous.”
I can’t speak. I’m swimming through a fog. “Jealous?” I manage to spit out.
“I—I wanted what you had with Alex. I was confused. I didn’t understand what I was doing.” She shakes her head again.
I have a swinging, seasick feeling. It doesn’t make any sense. Hana—golden girl Hana, my best friend, fearless and reckless. I trusted her. I loved her. “You were my best friend.”
“I know.” Again she looks troubled, as though trying to recall the meaning of the words.
“You had everything.” I can’t stop my voice from rising. The anger is vibrating, ripping through me like a live current. “Perfect life. Perfect grades. Everything.” I gesture to the spotless kitchen, to the sunshine pouring over the marble counters like drizzled butter. “I had nothing. He was my one thing. My only—” The sickness surges up and I take a step forward, clenching my fists, blind with rage. “Why couldn’t you let me have it? Why did you have to take it? Why did you always take everything?
