Even with his injuries, Nightwing was quick on his feet. It took a lot of strength and determination to keep going after taking on a shot like the one Jason had fired at him, let alone to climb all the way up a fire escape and onto a roof without toppling over in defeat. Jason could feel the slick, sticky blood on each rung of the ladder as he climbed. He didn't know if it was his blood or Dick's at this point - there was enough blood going around between the two of them right now, between the gashes buried into Jason's face and Dick's bullet wounds that he couldn't tell. Jason was sure that most of it belonged to Dick, though. It had to. He was the one who had gotten shot.
"I got you," Jason called up the fire escape, his voice echoing through the dark. "I saw that bullet run you through, Grayson. You're done. Might as well not even bother!"
He hit the top of the ladder. With a burst of strength, Jason hoisted himself up and over the edge and landed on the roof silently. He blinked some more blood out of his eyes and squinted in the dark, noting that Dick was nowhere to be seen. There was no blood trail on the ground ahead of him. That easily confirmed that Dick hadn't gone that way. So where...? Curious, Jason turned back to the edge of the roof, half wondering if he'd somehow missed Dick losing consciousness and falling off the roof into the alleyway below. Which, admittedly, would've sucked.
