The fluorescent lights of the facility had been dimmed for the night cycle, casting the narrow room in shades of grey and deeper grey. Luis Serra sat on the edge of his bed, his back against the cinderblock wall, his knees drawn up loosely, one hand resting on his ankle. He was wearing the standard-issue sweats, soft from repeated washing, and his hair was still slightly damp from the shower he'd taken an hour ago. He wasn't tired. He was never tired anymore.

Not since her.

The thought arrived like a physical sensation, a warmth that started behind his sternum and radiated outward. He let his head fall back against the wall, his gaze fixed on the ceiling where a single security light bled through the gap in the curtains. His eyes, in this low light, should have been struggling. They weren't. The world was sharp, defined, every shadow legible. He could count the threads in the curtain fabric from here.

Thank you, he thought, the words forming not as prayer but as conversation. I know you can hear that.

No response, of course. There never was. Not in words. But he felt her attention, that peculiar weightlessness that meant she was present, watching, there. It was like standing in a shaft of sunlight after years underground. He didn't need her to speak. He needed her to be.

His mind drifted backward, rewinding through the months like a scientist reviewing footage.

The first time she'd taken control, he'd been convinced he was dying. He'd woken—no, that wasn't right. He'd remained conscious while his body stopped being his. The terror should have been absolute. A mind like his, built on control, on prediction, on maintaining the illusion of agency—losing that should have shattered him.

Instead, he'd felt the dopamine hit.

Eight times normal. He'd done the math later, lying in this same bed, trying to quantify the ineffable. Eight times. It wasn't just pleasure. It was rightness. It was every question answered, every fear soothed, every wound sealed. His PTSD, that hypervigilant sentinel in his skull, had simply... stopped screaming. The anxiety algorithms kept running their probability forecasts, but they found nothing to fear because she was in control and she would not let harm touch them.

Them. He'd started thinking in plural. We. Not in a dissociative way. In a finally complete way.

He remembered the first time he'd seen his own eyes afterward. He'd shuffled to the bathroom—no, she'd walked him to the bathroom, her gait so different from his own jerky restlessness. Smooth. Deliberate. Like he owned the building. Like he'd never flinched at a dropped tray in his life. He'd looked in the mirror and seen onyx staring back, that deep, pupil-obscuring brown that should have looked alien and instead looked like home.

He'd opened his mouth, expecting... he didn't know what. A demon's voice? A goddess's proclamation?

"I have got to get a better mirror in here," he'd said. His voice. His sarcasm. His coping mechanism firing before his conscious brain could catch up.

And he'd felt it: amusement. Not heard it. Not seen it. Felt it, warm and fond, radiating from somewhere that wasn't inside his skull but also absolutely was. She thought he was funny. The entity that had taken over his motor cortex thought he was funny.

That had been the moment he stopped being afraid.

He was 31 years old. His career was in ruins. His name was controversial. His future was uncertain. And for the first time since he'd seen what his research had become, he was okay.

The warmth bloomed, full and certain, and Luis Serra, biologist, former high-containment researcher, current vessel of something beyond comprehension, smiled in the darkness of his room.

"So what now?"
