The step didn't echo.
It landed — the sound going down into the structure instead of out into the room. Leon felt it through his boots before he fully registered it as sound.
Another. Closer.
Not fast. Coming straight.
His grip tightened on the shotgun. "We're moving."
Marvin pushed off the wall. Not steady. Enough.
The girl was already on her feet.
The handle moved once. Stopped. Then the door came in — not shattered outward, not kicked apart, but the whole frame giving under a single sustained impact, wood splitting at the joints and dropping inward, striking the floor hard enough to bounce once before it settled.
He filled the doorway.
Too tall, hat brushing the broken frame, coat hanging without movement. The scale of him was wrong in a way that took a second to process and then couldn't be unprocessed.
Leon fired.
The shot hit center mass. No reaction. He fired again and the head shifted a fraction with the impact — not flinching, not recoiling, adjusting the way you'd correct your balance on uneven ground.
Marvin was already in the path of it.
He hadn't moved toward the figure — he'd just never moved out of the way. He stood where he was, hand near his weapon, and the figure walked past him with the complete indifference of something that had already made its calculation about what in the room mattered.
Marvin turned and watched it pass him.
Something crossed his face that wasn't fear. The expression of a man who has just understood that he doesn't factor into the equation — not as a threat, not as an obstacle, not at all — and is still deciding what to do with that information.
Leon stepped forward to put himself in the path of it instead.
The distance closed faster than he'd calculated.
A hand caught him at the vest and lifted, and in that half-second Leon understood with cold precision exactly how much stronger the thing was than anything he'd trained against. Then he wasn't thinking about that anymore because he was hitting the desk hard enough to break it, wood cracking under his back as it collapsed with him, the air leaving his lungs all at once.
The shotgun left his hands.
He lay there with the ceiling above him and the broken desk beneath him and the specific pain of someone who has taken a hit from something that didn't mean to kill him with it and still nearly did.
The figure's next step was toward the girl.
Leon's arm didn't respond the first time he told it to. Then it did.
He moved without processing the decision. Not toward the figure. Toward the side. The desk leg came loose in his hands as he wrenched it free — metal bent, half-torn already from the collapse — and he drove it low into the path of the next footfall.
Not to stop it. To change it.
The step landed on it. The angle shifted. Just enough.
The figure committed to the new direction without correcting.
It went through the locked door beside the armory.
The wall took the impact first, cracking along the frame. Then the door itself tore free — not cleanly, not all at once, the force going through it rather than stopping at it, the lock twisting out of alignment and hanging broken in the warped frame. The door dropped half-open.
Inside: racks. Weapons.
Leon saw it.
Didn't stop.
No time.
He got upright, got the girl's arm, and moved them toward the exit. Behind him the figure had reoriented — extracting itself from the damaged frame with the patient certainty of something that had briefly encountered an obstacle and was now finished encountering it.
"Go," Leon said.
They went.
The hallway opened dim and cluttered. Leon fired twice without slowing — one dropped, one staggered enough to clear the path — and pushed her forward. Her hand closed around his and stayed there, fingers tight with the specific pressure of someone who has made a decision about not letting go.
He cut left toward the library and drove through the doors.
The space opened — high ceiling, shelves running floor to gallery, the central staircase rising through the middle in a column of failing light.
Leon stopped.
Movement above. On the railing. On the ceiling.
One dropped to the floor ahead of them without a sound, landing in a crouch that held for a moment before the head tilted. Skull split open along the ridge, muscle exposed beneath. No eyes — just that tilted listening orientation, the tongue moving slowly in the air.
Another shifted along the railing above, claws dragging lightly against the wood. A third clung to the far shelving with its body pressed low, tracking something it hadn't identified yet.
The girl had gone completely still beside him.
Behind them the library door came open. Heavy. Unhidden. One impact, then stillness — and the stillness was worse than the impact.
Leon didn't turn.
He understood the geometry in one pass. The Lickers ahead and above. The figure behind. One available route along the left wall where the older shelving blocked the sightlines from the gallery.
He leaned toward her. "Don't run." Almost no voice behind it. "Slow."
The nearest Licker tilted its head further. The one above shifted weight, claws adjusting.
Then the footstep landed behind them.
The Licker on the floor snapped toward it instantly. The one above launched without warning, dropping past them in a rush of displaced air and landed on the figure with enough force that Leon felt the impact through the floor.
He moved.
One step, then another — careful, measured, keeping himself slightly between her and anything that might turn back. They passed within arm's reach of the remaining Licker on the shelving. Close enough to hear the wet sound of its breathing.
It didn't react.
Behind them something heavy reorganized the room without caring what was in the way.
Leon kept them moving toward the left wall. The shelving here was different — thicker, reinforced, older than the rest of the station, built into the structure rather than placed against it. Not library furniture. Something that had been here before the library was.
He hit it with his shoulder and it shifted — not loose, but seated into something deeper than the floor.
He stopped. Grabbed it properly. Pulled.
It resisted.
Then gave.
A heavy internal mechanism released with a dull mechanical drop that didn't stay in the room — it traveled down through the wall, through the structure, somewhere far below them. A second mechanism answered it. One part of the system. Not all of it.
Leon held still for one second, listening to what he'd done without understanding it.
Then: "Go."
They pushed through the side exit into the corridor beyond. Quieter here, the sounds from the library already muffled by walls and distance and whatever was still happening inside it between the Lickers and the thing that didn't know how to stop.
For a moment, almost nothing.
Then one step. Behind them. The same rhythm.
Leon ran.
His breathing was breaking now under the accumulated weight of it — the hits, the ribs, the distance already covered — and he pulled her with him through the dim corridor with the steps behind them growing louder and the station contracting around them into the only direction that wasn't already closed.
"Almost," he said.
He wasn't sure it was true.
Her grip tightened against his hand. Not panic. Not a plea.
Just holding.
Behind them, the steps came on — measured, patient, indifferent to the distance still between them.
