He had to end this quick. Getting up high was the first advantage he tried to take. Climbing the fire escape was harder this time around, his blood clung to the metal bars and made them difficult to grip at. With every movement it was getting harder to breathe. He focused on climbing. Put his energy into staying upright. So far so good. He could almost see the top of that roof, but he could also see and hear Jason following him close behind. He kept moving on that ladder as he heard a bullet strike way too close for comfort.
Pausing for a moment to breathe and let Jason catch up, he slammed a boot down onto his now exposed face aiming for those same vitals that Jason had so kindly struck on him. He could feel his muscles tightening again, his eyes were cloudy from blood loss. Move, move move. Was the only thought on his mind. Climbing over the ledge of the roof onto the flat surface he paused in the shadow cover behind a vent to breathe and wait for Jason's next move.
He felt himself stagger slightly, one of his hands pressed on his wound as beads of sweat rolled down the sides of his face. He couldn't take anymore hits like that or that was it. He was out of rangs and only really had smoke pellets left. What could he do besides wait, give Jason a minute to get to the roof and get the drop on him.
The second he heard movement on his rooftop, he was up and ready. A single light source from a nearby billboard cast heavy shadows on their new playground. Dick fingered a smoke pellet and waited. Jason had to be closer for his plan to work.
