Matthew followed the clacking of the metal heels deep into Hell's Kitchen, every step rippling out across the street and down the curb, lighting up the asphalt. The ripples mixed with the rain, every individual drop giving him constant flashes of the city - every sidewalk tile, every trashcan, every streetlight. A whole city as one surface, pulsing and radiating soundwaves and heat. Matthew himself spread noise, the low wet thud of his boots against rooftops feeding him information that he accepted, analysed, and discarded. Above all that was Matthew's mark, and now, despite the rain, he was picking up smells as well - wet leather, musky cologne...and the slight tinge of salt, mixed with oil and the unmistakable scent of gunpowder. The salt carried the sea with it, but Matthew already knew they were headed to the docks by their direction - but the oil and gunpowder was from the pistols Daredevil's mark carried, holstered beneath his coat around his torso. They'd been fired recently, but the man didn't carry the smell of blood with him, so Matthew assumed it was target practice or goods testing. They were drawing closer to the docks and he was learning more about his mark every step - testing pistols. Flashy fashion sense. Bald, wearing sunglasses, thin vest top. Something in his left pocket - the coat swung heavier on that side. He leaped another rooftop, putting a hand to his batons in mid-air. Something told him he'd need them.
Matthew kept on the mark's trail. They went a couple more blocks and then buildings gave way to warehouses and Matthew had to hit the ground if he wanted to follow. Warehouses were noisy and involved a lot of glass - in the rain, he didn't want to slip. Or put his foot through a pane. The guy carried guns, and bulletproof armour was hard to move in. Instead, he dropped carefully, leaping from the rooftop to the indent of a window a few stories down on the opposite building, landing with the balls of his feet on the outcropping and springing back, flipping backwards from the window and reaching out to grab a steel cable that was strung between the buildings another few stories down. His orientation didn't matter; he kept track of himself through proprioception and the buildings through sound, air pressure, the smell of brick and concrete. The cable flexed as it took his weight and he dropped the last few metres, rolling as he hit the ground and unsheathing his batons. He spun them in his hand and tested the retracting cable that strung them together, and then, satisfied, re-centered his hearing. The footsteps were still there, still his mark's. They'd been alone for a while now, and he hadn't changed his gait. Matthew slunk across walls and behind shipping containers, still in pursuit. They were by the sea's edge now, and the docks had turned into massive corridors of corrogated metal, walled off by cargo.
He whistled. A simple four-note tune, but it was clear in its purpose. A woman appeared from behind one of the containers. Matthew had heard her heartbeat as they'd approached - it remained calm. His mark's did not. He cleared his throat, and spoke:
"The guns are good. I'll take more pistols, and I want to add the assaults and the sniper. It'll all be useful." His heart rate was rapid, but his breathing and words remained steady. He was about to do something stupid.
"You sound like you're takin' a crew. He doesn't like supplying crews. They might get stupid and think they're competition." She replied, voice calm, heartbeat to match. She seemed to anticipate it.
"No crew. Just what's needed for the target. High-risk."
"If you're going after who I think you're going after you're going to need a crew. Not like you'd lose much on the split."
"I don't need the money." It wasn't a boast - his heartrate hadn't faltered, so he believed it. Either he was well-off or didn't care. "I'm not doing it because someone paid me to do it." Still telling his truth. "I'm doing it because it can be done. And everyone's going to know my name when I do it." He seemed proud in himself, puffed up on his own stupid ego. The woman just shrugged.
"Whatever. Just make sure you keep whatever trouble you stir up in Gotham. He doesn't need egos bringing trouble back here. You know what he wants for the goods. You can wire it direct."
"I know what he wants." Muttered the man, voice low - trying to be threatening. Matthew primed himself, every muscle wound tight, ready to spring. His fist clenched around his batons. The man unholstered his pistols, arm stretching out to hold it in front of him. "But only I get what I want."
The woman would have begun to laugh, had Matthew not loosened his body and launched from the corner, already raising his arm to strike with the baton - but the woman had seen his fast movement and the man had noticed her, throwing his arm out behind him to the left without looking and pulling the trigger. Matthew felt the arm's movement through the air, the heat from the muzzle and the sound of the gun telling him the exact path of the bullet and he was able to throw himself backwards to the ground immediately, feeling the air ripple and vibrate above him as the bullet slammed into a shipping container and ricocheted away. Matt barely had time to register the good shot before he flicked the top of his baton as he fell, releasing the cable that tied the two together and whipping his arm out as he hit the floor, hitting the man's inside wrist, nearly breaking it with the force of the throw and forcing him to drop the pistol. He slid in the rain, pitching forward and pushing up on his feet as the mark drew his other pistol in his remaining hand. He barely had to time to wrap his finger around the trigger before Matt brought his stick straight down on the arm, cleanly breaking the ulna as the shooter yelled out in pain, silenced by a boot to the chest as the other pistol clattered to the ground. The woman was pissed - at the mark.
"You brought the fucking Devil with you? You let him follow you? You're a fuck-up and a nobody and you thought you were going after the fucking Bat?! After threatening me? He'll come see you soon, don't you worry about that. Then, people are going to know who you are."
She was gone before Matt could stop her - not that it would have been useful to do so. He took a deep breath through his nose, analysing all the scents he could find before isolating one that would be easy to follow up on - fish, variety of, from the nearby market she obviously frequented - before he delivered a sharp heel-kick to the skull of his mark. Extorting an arms-dealer to get weapons so he could go after Batman. He probably wasn't doing much damage that hadn't been done already.
It didn't take long to deliver the no-name to the PD, and Matt wondered if he'd see him later in court. Probably not - he didn't see much of his handiwork. He usually got them on the streets before he needed to defend their victims in the courtroom. He spent the rest of the night on more patrol, thinking over his new lead through the arms dealer and listening to his city. Gotham had its own problems; but Hell's Kitchen wouldn't see anymore trouble tonight.
