FIRST KILL

The front door didn't just rattle. It groaned as the wood began to splinter under a weight that didn't care about physics.

[Warning: Hostility at the Threshold,] LUS whispered, the voice now a low, predatory purr. [Asset 'Ronan' is prepared for traditional combat. Recommendation: Exceed expectations. Finalize the Wraith Pulse calibration.]

I didn't wait for the door to fail. I didn't wait for Ronan to give the order. I stepped forward, the obsidian knife held low, and pulled the deadbolt myself.

"Audrey, wait, "

I wasn't waiting for anything anymore.

The door swung inward, and the thing in the hallway lunged. It was the neighbor from 4C, a man who'd once complained about my music being too loud. Now he was just a geography of gray skin and unhinged hunger.

Ronan raised his handgun, but I was already in the arc.

[Wraith Pulse: ACTIVE.]

The Flash hit me, but this time it wasn't a memory of death. It was a blueprint of the kill. I saw the heat signature of the creature's core, the fragile link between its spine and its brain. The air in the hallway thickened, turning into a lens I could move through.

I didn't stab. I moved past him with a liquid speed that smeared the orange hallway light into a blur. As I passed, I slammed my free hand against the creature's chest and let the Pulse go.

It wasn't a sound. It was a concussion. A wave of subsonic force erupted from my palm, shattering the creature's ribcage and sending it flying backward into the opposite wall with enough force to crack the plaster.

It didn't get back up. It didn't even twitch. It slumped into a pile of gray dust and static.

[First Harvest Complete.] [Reward: 20 Strength Points. 10 Perception Points.] [Skill Evolution: Wraith Pulse Level 2, 'Siphon' Unlocked.]

I stood in the hallway, chest heaving, but it wasn't exhaustion. It was a rush, jagged and electric, the kind that made the smoky gray in my eyes feel like it was burning from the inside. I looked down at my hands. Perfectly steady. I felt incredible. I felt like the world was finally starting to make sense, and some small, distant part of me understood that was exactly the problem.

"Audrey."

Ronan was standing in the doorway, gun lowered, finger still tight on the guard. He wasn't looking at the pile of ash in the hallway. He was looking at me, and there was something new in his crystalline blue eyes, not just recognition. A flicker of genuine, lethal wariness, the kind you don't fake and don't fully shake off just because the danger's passed.

"You're doing it again," he said, his voice dropping to that dangerous, subsonic rumble.

"Doing what." My own voice came out thinner than I wanted it to.

"Smiling," he said it like an accusation. "You just turned a man into a memory, and you're smiling like you won a bet."

"Maybe I did."

He stepped over the threshold, closing the distance until I could taste the ozone and the gunpowder, but he stopped short of touching me, close enough that I felt the heat off his skin, far enough that it read as a choice.

"That's the part I don't have an answer for yet," he said, quieter now. "Whether that's the Pulse talking or whether that's just you."

The question landed harder than I wanted it to. I didn't have an answer either, not one I trusted, so I said nothing and let the silence do what my voice couldn't.

His eyes moved over my face, cataloging again, the way he had over the drill and the boards, except this time I understood what he was actually measuring. Not whether I was capable. Whether I was safe. Two very different questions, and I watched him realize, in real time, that he didn't know which one he'd just gotten the answer to.

"You're not going to apologize for it," he said. Not a question.

"No."

"Good." But it didn't sound like relief. It sounded like a man filing something away for later, the same way I used to file every slight Jason handed me, except Ronan's version of filing looked like a held breath instead of a closed door.

He reached for my jaw then, slow enough that I could have stopped him and didn't, his thumb tracing the line of my throat, rough and warm and deliberate. My pulse answered before I told it to.

"You're not afraid of me," I said.

"No." His voice had gone low, closer to the sound the knife made when it hummed against the counter. "I'm afraid of how fast I stopped being afraid of what you just did."

I leaned into his hand, the contact sparking against the LUS current still running under my skin, and for one full breath neither of us moved, his mouth close enough that the space between us felt like its own kind of countdown.

"Don't get ahead of yourself, little ghost," he murmured, and then, deliberately, he stepped back.

Not far. Just enough. Enough that I felt the absence of his hand like a held note going silent.

"Why'd you stop?" I asked before I could decide; I didn't want to know the answer.

"Because I don't know yet if I'm choosing this or if something's choosing it for both of us." His jaw tightened. "I'd like to find out which before I do something I can't take back."

[Evolution Synergy Detected: 12%,] LUS hummed, sounding almost pleased with itself. [Dividend Status: Secured. Interest accruing.]

I pulled back too, the obsidian knife still humming faintly in my grip, and told myself the ache in my chest was adrenaline and nothing else. The first sirens were joined now by the sound of distant glass breaking, block after block, the city beginning to bleed out into the dark.

Ronan holstered the gun he'd never needed to fire and looked at me like a man doing math he didn't trust yet.

"We should move," he said. "Before something bigger than one Scout finds this address."

"Move where."

"Somewhere with better locks." A ghost of that almost-smile, gone as fast as it came. "And somewhere I can watch you do that again without wondering if I should be worried."

I picked the ash off the hallway floor with my boot, the last of the neighbor from 4C scattering into nothing, and didn't ask him to finish that sentence.
