"Hey, look at that!" Bart called up to the rooftop at the lone figure crouched in the darkness. A moment later he was standing in front of the caped hero, crossing his arms with a grin. "I know they say cats have nine lives, but maybe they should change the saying to bats." He chuckled, lifting his goggles over his eyes and up onto his forehead. "Listen, I know we never really officially met or anything, but I, uh, I heard about what happened." He said, hoping that this little interaction wouldn't get him pushed off the roof. "And, um, well, I just wanted to say that I'm glad that Gotham has its Robin back." He said a little nervously, but sincere nonetheless, kicking absentmindedly at a pebble and sending it skidding across the roof with a tiny plink...plink...plink.
