Desmond hadn’t moved his hand off his chest in twenty minutes, and the rib on the table in front of him hadn’t stopped answering it.
He sat on an upturned crate, the ridge under his sternum gone from cold to warm to something he didn’t have a name for.
Three in the morning.
The crew asleep in the back.
A helicopter somewhere over the harbor, chopping slow patient lines through the dark.
He pulled his hand away and looked at the rib.
Ten inches of ridged alloy, faintly iridescent where the light caught it wrong.
Sellable.
Exotic but not strange.
He’d told himself that twice now and it still wasn’t holding.
The warmth at his sternum pulsed once, faint, like a second heartbeat half a beat off.
Desmond leaned forward and put his palm flat on the table six inches from the rib.
Nothing.
He moved his hand closer.
Four inches.
Two.
The warmth under his shirt spread, and the rib—
He pulled his hand back.
The rib sat there.
Inert.
Cold metal on a colder table.
He counted to ten and tried again, slower this time, cataloguing it the way he’d catalogue a live wire.
Proximity.
Contact.
Angle.
At two inches the warmth spiked and the rib gave off a low hum he felt in his teeth more than heard.
He froze.
The hum held, steady, like a bone in a cold room, and then it faded when he pulled his hand away.
Right.
So it answered to him.
Specifically.
He sat back and pressed both hands to his face and tried to tell himself that was fine, that was something he could work with, that he’d cracked worse problems than alien scrap that hummed when he got close.
The helicopter’s blades cut closer, and he stopped lying to himself.
Behind him, in the narrow back room the crew used for sleep, someone coughed.
Desmond turned his head and listened.
Bram’s cough, wet and nervous.
The boy hadn’t slept well since the Battle.
None of them had, but Bram wore it worse than most.
Desmond stood and walked to the stove—a rusted camp burner they’d scavenged three months back—and lit it with hands that were steadier than they had any right to be.
The flame caught.
He filled the kettle from the jug and set it to boil, then leaned against the wall and waited.
The helicopter passed overhead.
Close enough that the shed’s tin roof rattled.
The warmth at his sternum flared, sudden and bright, and Desmond hissed through his teeth and grabbed the edge of the stove without thinking.
The burn was immediate.
Sharp and clean and exactly the kind of stupid a tired man made at three in the morning.
“Boss?”
Desmond turned.
Bram stood in the doorway, eighteen years old and too thin, wrapped in a coat two sizes too big and watching Desmond the way a dog watches the man holding the leash.
“Burnt my hand on the stove,” Desmond said.
He held it up, palm out, so Bram could see the red mark across his fingers.
“Kettle’s on.
Go back to sleep.”
Bram didn’t move.
“You all right?”
“Fine.
Tired.
Go on.”
The boy watched him for another long moment, weighing something Desmond couldn’t see, and then he nodded and turned and went back into the dark.
Desmond waited until he heard the cot creak, then let his shoulders down and pressed his burnt hand to the cold wall.
The pain helped.
It gave him something to think about that wasn’t the warmth or the hum or the fact that he’d just lied to a boy who trusted him.
He walked back to the table and looked at the rib.
The helicopter’s rotors were louder now.
Circling.
The grid tightening.
Desmond picked up the rib.
The warmth spiked again, immediate, and the hum came up through his hand and into his chest and settled there like it had been waiting for permission.
He held it for a five-count, then slipped it into his pocket and pressed it flat against his sternum, just over the ridge.
The hum stopped.
The warmth evened out, steady and low, and the wrongness in his chest quieted for the first time since he’d cracked the core.
Right.
So it wanted to be close.
Or he wanted it close.
Or something in the middle that he wasn’t going to work out tonight.
He turned to the table.
The sell-bag sat in the corner, half-full of scrap they’d pulled over the last week—mundane Chitauri plating, the kind every crew on the water was moving.
He pulled a chunk of it free, similar size and weight to the rib, and dropped it on the table where the strange piece had been.
Marce would sell it at dawn to the walk-up buyer.
The buyer would take it, price it low, and move it before the cordon tightened.
And Desmond would keep the rib that hummed, and no one would ask why.
He was still standing there, cataloguing the lie, when the helicopter passed directly overhead.
The scanner beam cut through the shed’s tin roof like a blade.
White light, sharp and surgical, grid-mapping everything it touched.
And the rib in Desmond’s pocket went ice-cold.
Not fading.
Not cooling.
Dead cold, instant, like something had reached in and shut it off from the inside.
Desmond froze.
The beam swept across him, across the table, across the mundane scrap in the sell-bag, and kept moving.
The helicopter’s rotors faded south, and the cold in his pocket stayed exactly where it was.
He waited.
Ten seconds.
Twenty.
The beam didn’t come back.
Slowly, carefully, Desmond pulled the rib from his pocket and held it in his palm.
It was cold.
Inert.
The hum was gone.
The warmth was gone.
It sat in his hand like a piece of dead metal and nothing else.
He pressed it flat to his chest again, over the ridge, and waited.
Five seconds.
Ten.
The warmth came back.
Slow, cautious, like something testing the air before it moved.
The hum followed, low and steady, and the wrongness in his chest settled again.
Desmond sat down hard on the crate and stared at the rib in his hand.
It had hidden itself.
Not gone dormant.
Not stopped working.
It had felt the scanner and it had hidden, the same way he would have hidden, the same way any scavenger on the water hid when the cordon came close.
He turned the rib over in his palm, feeling the ridges, the faint warmth, the low hum that was already fading back to nothing now that the threat was gone.
Whatever this was, it already knew how to survive.
And it knew how to do it the same way he did.
By not being seen.
Desmond slipped the rib back into his pocket, pressed his burnt hand to the wall, and sat in the cold shed and listened to the helicopter fade into the distance.
The crew slept.
The water lapped at the pier.
The node at his sternum settled back into its low, patient warmth, and Desmond sat in the cold shed with a plain fact he couldn’t unknow.
The thing fused to his chest had learned to disappear before he had.
And it had done it without asking him first.
