26. Xen
In the forty-eight hours since Sophia had been secured, he had come to know her better than anyone else ever could.
A full-spectrum scan, down to the mineral makeup of her bones. Neural telemetry mapped in microbursts, timed to induced REM. Xen traced her dreams while she slept, and measured what parts of her sparked when she imagined escape.
But the lattice was the masterpiece.
Xen had to manage thousands of microneedles, each no thicker than a hair. Pressed against her skin like a kiss. Shallow enough to avoid pain. Deep enough to breach the capillary bed.
Because blood was honest.
It didn’t posture. It didn’t lie.
It touched everything—muscle, nerve, organ—and it carried the memory of all three.
So he spoke to it.
The polymer was bio-adaptive—sensitive to chemical gradients, pressure shifts, thermal flux.
It didn’t fight her. It learned her. Moved with her.
It charted the soft geometry of her pulse, memorized the rhythm of her flow.
And when it knew her well enough to predict her, it hardened.
Quietly. Capillary by capillary. A second network beneath the first. A net, inside her blood.
He let it rest. Let it root. Let her body believe she was healing.
Because when he cut her open now, she would not bleed.
Not unless he wanted her to.
And now, as he prepared to cut, he didn’t need clamps or cautery to bind or crush.
The lattice did the work for him—constricting capillaries before the blade ever touched her skin.
A thousand tourniquets firing in microscopic unison, responsive to his commands.
She wouldn’t bleed unless Xen wanted her to.
She wouldn’t bruise unless he allowed it.
But she would likely scar.
There was no way to scrape the invasive filaments off her nerves without exposing them, which meant, to some degree, he would be flaying her alive.
So she would be covered in scars when she healed, but if he did his job right, she would still maintain all of her preexisting function—and it would be better than the alternative.
Xen adjusted his optical zoom without looking up, tracing a filament from the outer edge of her fifth digit all the way back to her spine as Thorne seethed behind him.
“How much longer?”
“As long as it takes,” Xen told him. Just as he had told him before.
The Maukin, vampire, and rest of the MSA team had found a series of dead-drops and information relays that had eventually come to a dead end.
Xen suspected that if he’d been among their number, he would’ve been able to find the next one—but he hadn’t been able to trace Sophia’s minders back to Sirena because he had been too busy here, feigning her signal until he could cut her off from her minders entirely and begin the laborious process of saving her life.
And the entire time, Thorne had been there. Frozen into stone during daylight; a hulking, pacing gargoyle during night.
“She’s mine,” Thorne repeated, with the tone of a man who was slowly dying, from behind the threshold Xen had burned into the floor with a UV stylus.
“I know,” Xen said.
Thorne laughed, bitter and low. “You don’t know anything. You’re just a clanker.”
Xen didn’t look up. He kept his eyes on Sophia’s spine, where something that did not belong was pretending to be part of her. He reached in with a fiberhook and teased the base of a filament loose, running just enough current down it to encourage it to release from the nerve it was wrapped around.
“I know what it is to watch someone suffer and be able to do nothing. To want to trade every piece of yourself for one moment of relief. I know what it’s like to hold back, even when it’s killing you—because it’s what they would want.
And I know what it means to want to be seen by someone who doesn’t even know you exist. To hold your whole self in silence, because you believe you can never touch them. ”
Xen didn’t expect a response.
There was only the hum of the surgical suite. The soft whisper of air filters. The quiet nothingness of a body kept steady by intention alone.
But something had shifted in the room.
The kind of stillness that came when one truth brushed too close to another. When someone who didn’t think machines could feel realized he might be wrong.
“Do you . . . love her?” Thorne asked, then quickly corrected himself. “No—do you think you’re in love with Sirena?”
“I do not think anything,” Xen said. “I know.”
He didn’t whisper it. Didn’t look up. Didn’t stop working.
The filament in his grasp loosened with a slow twitch, pink-tinged metal glistening under the surgical lights.
A single flick of Xen’s wrist and the thread detached. He laid it carefully aside.
Across the sterile barrier, Thorne stood like a fault line under pressure.
Xen could feel the tension radiating from him even without looking—fury held in check by duty. Grief masked by impatience.
But he didn’t speak again.
Not while Xen worked.
Not while Sophia’s spine was exposed.
Not while her life still hung in delicate balance.
And when the first rays of dawn filtered in through the shielded skylights, the argument ended—not with a word, but with a crackle of stone.
Thorne turned to granite mid-glare. Arms crossed. Expression frozen.
Silent. Watching.
As if petrified not just by the sun, but by what Xen had dared to admit.
