There was one person in Hell's Kitchen who didn't need to look up to know that there was someone sneaking through his shadows. The sound of boots crunching into the gravel topped roof, the fluttering sound of a loose, thin material- a cape?- the low hum of electronics buzzing through the night, a heartbeat... and some very interesting smells to accompany all of the sounds- particularly, the smell of an entirely odd and unique lubricant that Matt could only place on one other person, and as he listened intently to the heartbeat of the guest in Hell's Kitchen, it became apparent that the two people with that smell were one and the same.
So what was Bruce Wayne doing in Hell's Kitchen in the middle of the night in a cape?
With his billy clubs tucked into the holster on his belt, Daredevil reached up for the lip of the roof, hooked it with both hands and pulled himself up silently. Landing toe first then sinking down to the balls and finally the heels of his feet minimized the sound that was made when he put his feet down on the gravel rooftop, sneaking closer to the stranger other investigator.
"You shouldn't be here." He said to announce his presence and to make it clear that he wasn't welcome. If anyone heard that Bruce Wayne was sniffing around the crime scene where his late employee had been murdered, not only would he be in more legal trouble than most other millionaires could afford, but he would also be ruining Matt's case, which he cared about more than Wayne's bankroll.
And yet, he wasn't trying to run him off. If he'd bothered to come out here to try to find answers, maybe he could help Javier Martinez after all- even if he had come in thick boots and a cape.
"They cleaned the scene weeks ago- organized crime got here before the police and scrubbed what they were doing from the building, but the rumor is that there was an arms deal going down when the shooting started." Rumor was all he had though- no one, not any of the people Daredevil had shaken down would talk. They all didn't know nothin', hadn't seen nothin' and weren't sayin' nothin'-- and Daredevil could be very persuasive. So whoever had them scared was doing a damn good job of keeping them in line.
