"Tsk. It's like you want me to take away your fun." Dick said into the com while patting his gloves together from the fried wires. He then hurried down the hall. Damian got the three to himself, Dick got one unfortunate who peeked his head out from an office to figure out what happened to the power. Dick took him out as he ran by with one neat chop. The next person who came around the bend had a gun out. Nightwing stepped off one wall, onto the opposite side, dropped and rolled right into the man's legs, each shot missing him. His elbow came back, his other hand snatching the firearm. The gun cartridge went flying and hadn't hit the ground before he landed the strike that made the thug faceplant into the floor.
So he approached and watched the last of Damian's fight, leaning against the wall with his head tilt and an amused smirk as the new Robin took the thugs out with fashionable brutality.
"Nice. Should be some fellows down in the lower basement," he said, thumbing over his shoulder. "Race ya!" Then he dashed on ahead.
