Project Zero.

My heart seizes. I’d thought—Hideo had thought—that this nickname was just a hacker name, his marker. And it was. But what it really referred to was what Taylor called him. Project Zero. Study Zero. Their first experiment.

Taylor lets out a deep sigh before closing the folder in her hand and sliding the papers back toward the researcher. “Sasuke’s time is limited. We can’t afford to wait around.”

Before I can fully process what I’d just witnessed, the scene shifts to a small boy crouched in one corner of a room. Immediately, I recognize this as the same room I’d seen Sasuke in during our Duel.

So Taylor had taken him. She was the one responsible for that day in the park, when a young Hideo called for his brother and never heard him answer. She unknowingly triggered the start of the NeuroLink itself, the result of Hideo’s overwhelming grief. The reason Tremaine’s lying unconscious in a hospital bed.

She’s the reason why I’m even here, ensnared in this madness.

The scene now seems like dawn, with the barest hint of light from the windows, but Sasuke’s bed looks untouched, like he’s been sitting in the same spot all night. Instead, he stays in the corner with his knees tucked up to his chin, still wearing that white, long-sleeve sweater with the symbol embroidered on one sleeve. His fingers worry endlessly at the blue scarf around his neck.

The same scarf that Hideo had wrapped around him on their last day together.

The door finally opens, casting a slanted rectangle of golden light onto the crouched boy. Instead of scrambling to his feet, he just shrinks farther against the wall and tightens his grip on the scarf. In the entryway stands a tall woman I recognize as Taylor.

“How do you feel today, Sasuke?” she says in a gentle voice.

“Dr. Taylor, you said if I stayed quiet, you would let me go home today.”

Sasuke replies in English, and his young voice sounds so innocent it pierces my chest. This was when he was still fully himself.

Taylor sighs softly and leans against the door. Her kind face seems so sincere that, if I didn’t know better, I’d genuinely believe that she loved him as a mother would. “And I meant that, sweetie, with my whole heart. You’ve been so good. We just have a little bit more to learn about you, and then we’ll take you home. Can you do that for me?”

Sasuke tilts his head at the woman. “Then I want to call my mom first,” he says, “to tell her that I’ll be coming home today.”

He’s only seven, but he’s already trying to negotiate. In this moment, I’m fiercely proud of him for not falling for Taylor’s trusting voice as easily as I had.

Taylor must have had the same thought as me, because Sasuke’s words bring a smile to her face. “You’re such a smart boy,” she says, a note of admiration in her tone. She walks over to him and crouches down to lean on her knees. “But today, we just need to do a quick scan of your brain. If you talk to your mother on the phone, it might upset you, and your mind won’t be as calm as we need it to be. But I promise, it’s so easy—you’ll blink and it’ll be done. Then you’ll be on your way. Doesn’t that sound nice, Sasuke-kun?”

Sasuke ignores her attempt at an affectionate honorific. “No.”

Taylor smiles again at his reply, but this time she just looks on as a researcher steps in. Sasuke starts shaking his head as the man reaches him and tugs on his arm. “I’m not going,” he says, his voice turning more urgent.

“Now, Sasuke-kun,” Taylor says. “If you don’t, you’ll force me to take away your scarf.” She reaches out and taps the scarf’s fabric once, teasingly. “And I know that would make you very sad.”

At that, Sasuke freezes. He turns his large eyes up at her.

“I’m only trying to help you, you know,” she says softly to him, reaching out to pat his cheek. “That’s what your mom and dad were hoping for, when they signed you up. They wanted this for you, do you know that? That’s why you’re here.”

His small fingers close so tightly around the tail of his scarf that, even in the recording, I can see his knuckles turning white. Sasuke casts a reluctant glance back at the room before he follows Taylor and the researcher out. The door shuts again, returning the space to darkness.

My hand comes up to cover my mouth. While Hideo’s parents searched frantically for him, while Hideo lost his own childhood fixated on his brother’s disappearance, Sasuke was being held here against his own will.

The next scene opens back in the testing room. This time, Sasuke is sitting alone at one of the desks with his head resting on his arms. He’s staring blankly off into space. When he shifts, I notice a telltale pinprick in the bend of his left arm. A thin stripe of hair has been shaved off the side of his head, and there, near his temple, I see another pinprick.

The door opens. A girl steps in, whom I now recognize as young Jax. She sees him, hesitates, and then twirls one of her pigtails around her finger. She takes a seat next to him.

“Hey,” she says.

He doesn’t say a word. He doesn’t even seem to notice her in the same room.

When he stays silent, Jax bites her lip and nudges his arm. Sasuke lifts his head to glare at her. “What do you want?” he mutters.

Jax blinks at him. “I’m Jackson Taylor.”

“Oh. You’re the daughter.” Sasuke looks away again and puts his head down. “I remember you from the study.”

Jax scowls and puts her hands on her waist. “Mom said you might like some company your own age, for a change.”

“Tell your mom I’m not interested in whatever she’s thinking up.” He pauses to give her a skeptical look. “You don’t look all that sick.”

She smiles at him. “The drug study they were doing on us? It’s been working really well on me. Mom says it’s a miracle.”

Sasuke stares at her for a second longer before turning away again. “Good for you.”

“Hey, it’s slowed down your disease, too. Maybe you’re turning into a bunch of supercells. That’s what my mom said. She said the study helped ten percent of us.” She hesitates. Her eyes wander to the shaved stripe along the side of his head. “What are they injecting you for?”

Sasuke rests his head against his arms and closes his eyes. “Why don’t you ask your mom?” he mutters.

Jax doesn’t say anything. Her cheeks flush in apology.

When she still doesn’t reply, Sasuke looks up and sees her expression. He sighs. After a moment, he seems to take pity on her. “Trackers,” he explains. “They need it in my bloodstream. That was the injection. They said it’s preparation, for my procedures.”

“Oh.” She studies his face. “You don’t look so good.”

He goes back to closing his eyes. “Go away. My stomach hurts, and I feel sick.”

Jax stares at him as he breathes evenly in and out. After a while, she straightens to leave. “I was going to ask if you wanted to check out this hidden nook I found, up near the institute’s ceiling. And my mom doesn’t know about that.” She starts to walk away. “There’s a metal grate that’s open to the fresh air. It might make you feel better.”

As she goes, Sasuke lifts his head to look at her retreating figure. “Hang on,” he says. When she turns back around, he clears his throat, suddenly shy. “Where is it?”

Jax smiles and tilts her head. “I’ll show you.”

“I’m not supposed to leave the room.”

Jax winks at him. “No one tied you down, did they? Now, come on.” She steps out the door, and a second later, he scoots his chair back and follows her.

There are several scenes like this one, each showing the two of them hanging out in the empty study room, or in the hallways, or in the back shelves of the institute’s library. One scene is from Jax’s point of view—she’s kneeling on the tiles of a bathroom floor, gently patting Sasuke’s back as he throws up over and over again into a toilet. Another is of Sasuke making funny faces at her until she bursts out giggling.

Yet another is of them crammed into a tiny wedge of space together, over which a metal grate exposes a square of the night sky. Jax seems lost in thought, absently pointing out one constellation after another. She stops talking long enough to glance over at Sasuke, only to see him staring at her instead of the stars. He turns his head hurriedly away, but not before she catches the blush on his cheeks. She grins. Then she gets serious.

“Hey—do you know what a kiss is?” she asks him.

He shakes his head. “You mean, like a kiss from my mom?”

“No, silly, gross.” Jax laughs before steeling herself. “I mean the kind you give to someone you like,” she murmurs. “In that way.” Then she leans over and presses her lips quickly and quietly to his cheek before jerking away.

Sasuke stares wide-eyed at her, his face pink in the night. “Oh,” he says hoarsely.

“I saw it on TV,” Jax replies. She laughs nervously, a little too loud, and it makes Sasuke laugh in return. He kisses her cheek back. It makes her giggle even harder. Soon the two have dissolved into quiet laughter.

I look away to the Jax standing beside me. She nods toward her younger self. “These are my Memories,” she says to me as we continue to look on. “Taylor had them recorded and archived after the NeuroLink came out.”
