The drop was only five feet, but it felt like falling down a well.
Arvin hit the gravel and trash between the rails. His knees buckled, sending a shockwave of pain up his spine. Nova landed beside him, slipping on something wet—oil or sewage—and scraping her palms against the rusted sleepers.
"Move," Arvin wheezed.
Above them, in the lit subway car, a fresh volley of gunfire erupted. The pop-pop-pop was muffled by the thick glass, distant and surreal.
Nova didn't argue. She scrambled up, her jeans soaked in the black sludge of the track bed.
They ran.
The darkness wasn't empty. It had weight. The air was thick with the smell of old iron, rat droppings, and the metallic tang of ozone from the third rail humming a foot away from their ankles.
"Watch the rail!" Arvin hissed, grabbing Nova's jacket to steer her away from the lethal current.
They made it fifty yards before the adrenaline crash hit Arvin. His legs turned to water. He stumbled, catching himself against the tunnel wall. The concrete was slimy with condensation.
"Arvin," Nova whispered. She was breathing hard, her voice trembling. "We have to keep going. He'll come after us."
"He won't," Arvin gasped, clutching his chest. "Scorn... she's good. She'll pin him down long enough."
"For what?" Nova snapped. She clicked on her phone's flashlight. The beam cut through the gloom, illuminating swirling dust motes and the endless, repetitive arch of the tunnel. "Who was that, Arvin? Why did he call you 'Subject Zero'?"
Arvin closed his eyes. The headache was back, but it was different now. It wasn't the sharp, icy spike of Dante taking the wheel. It was a dull, throbbing heat at the base of his skull. Like a fever trying to break.
Do not answer her, Dante's voice was faint, static-filled. I am... re-routing. Systems damaged. The door... the hinges are loose.
"He's from the Institute," Arvin said, ignoring Dante. He looked at Nova. The flashlight beam made her face look stark, shadows hollowing out her eyes. "They made me."
"Made you?"
"My brain. They tried to split it." Arvin pushed off the wall. "We need to find a service ladder. Get to street level."
They started walking again. The tunnel curved. The sounds of the station faded, replaced by the rhythmic drip-drip-drip of water leaking from the city above.
"Arvin," Nova said after a minute. Her voice was tight.
"Yeah?"
"Stop walking."
Arvin stopped. "What?"
"Look at your shadow."
Arvin looked down. The beam of Nova's phone was hitting him from the left. His shadow stretched out long and distorted against the curved wall to his right.
It was normal. Just a dark shape.
"I don't see anything," Arvin said.
"Wait," Nova whispered.
They stood in the silence.
Then, Arvin saw it.
He wasn't moving. Nova wasn't moving. The light was steady.
But his shadow turned its head.
The silhouette on the wall rotated its neck slowly, looking back the way they had come. Then it looked at Nova.
The shadow grinned. It wasn't a trick of the light. The jagged profile of the shadow's mouth opened wide, too wide for a human jaw, revealing teeth that weren't there on Arvin's face.
Hungry, a voice whispered.
It didn't come from Arvin's head. It came from the walls. A wet, slithering sound.
Nova stepped back, the flashlight shaking in her hand. The beam danced wildly, making the shadows jump and flicker.
"Did you say that?" she asked, backing away.
"No," Arvin said. He felt cold. Colder than he had ever felt.
Arvin, Dante warned, his voice surging with panic. Don't look at it. If you acknowledge the projection, you strengthen the bond.
"It's just a trick," Arvin said, his voice cracking. "Trick of the light. Stress. We're in shock."
He reached for Nova, but she flinched.
"That thing," she pointed at the wall. "It's looking at me, Arvin."
The shadow raised a hand. It pointed down the tunnel, deeper into the dark.
This way, the walls whispered. Fresh meat this way.
"We're going the other way," Arvin said instantly. He grabbed Nova's wrist, hard. "Now."
He pulled her forward, ignoring the shadow that was now miming a throat-slitting motion on the wall.
They hurried deeper into the gloom. The tracks split. A service tunnel branched off to the right, marked with a faded 'AUTHORIZED PERSONNEL ONLY' sign.
"There," Arvin pointed. "That leads to a ventilation shaft. We can climb out."
They ducked into the narrower tunnel. It was tighter here, the ceiling lower. Pipes ran along the walls like arteries.
Suddenly, a rat—huge and grey—skittered across Nova's foot. She yelped, stumbling into Arvin.
Arvin caught her, but the momentum slammed him back against a cluster of rusted pipes.
Clang.
Pain exploded in his shoulder.
And for a second, the world flickered red.
Containment breach! Dante screamed.
Arvin slid to the floor, clutching his head. "Get away from me," he groaned through gritted teeth.
"Arvin?" Nova knelt beside him. "Are you hurt?"
"Run," Arvin gagged. He could feel it. It wasn't like Dante. Dante was a pilot stepping into a cockpit. This... this was oil flooding the engine. It was viscous and heavy.
His left hand shot out and grabbed Nova's throat.
It wasn't Arvin.
Nova's eyes went wide. She clawed at his hand, dropping the phone. The light spun across the floor, coming to rest facing them.
In the stark lighting, Arvin's face was contorted. The left side was slack, the eye rolling back. The right side was terrified.
"Run!" Arvin screamed with the right side of his mouth.
His left hand squeezed tighter.
"Please," Nova choked out. She kicked him in the shin. Hard.
The pain clarity cut through the fog.
Arvin used every ounce of will to smash his own left hand against the concrete floor. Once. Twice. The bones crunched.
The grip loosened.
Nova scrambled back, gasping for air, clutching her neck.
Arvin curled into a ball, cradling his broken hand. He was sobbing. But beneath the sobs, a low, guttural chuckle was bubbling up from his chest.
"He likes you," Arvin whispered, the voice layered—his own tenor mixed with a gravelly bass. "He thinks you have... texture."
Nova picked up the phone. She stood over him. She didn't run. She looked at the man warring with himself in the dirt.
"Dante?" she asked, her voice raspy.
"Dante is sleeping," the double-voice crooned. "He's tired. The Driver is asleep at the wheel."
Arvin slammed his head against the pipe. Thud.
"Shut up!" Arvin yelled at himself.
He looked up at Nova. His eyes were bloodshot, tears streaming down his face. The red tint was fading.
"Nova," he wept. "You have to tie my hands. Please. Before he comes back."
Nova hesitated for only a second. She ripped the strap off her purse. She moved in, efficiently binding his wrists together behind his back.
"Get up," she said. Her voice was cold again. Practical. "We're finding that exit. And when we do, you're going to explain exactly who the hell 'He' is."
She hauled him to his feet.
On the wall behind them, Arvin's shadow was no longer bound. Its hands were free, and it was waving goodbye.
