Doug sat on the edge of the roof, his feet dangling over, riding that initial sensation fear of falling over the edge into a place of calm and awareness of the city around him. Gotham was alive... and it usually had a foul temper, but there were moments of calmness, and he found in his meditation practices that this was the best place to start.
However, something carried to his ears... talking... and not from the street below, but a nearby rooftop. A girl's voice... Batgirl didn't speak, and not like that, and he was curious who might be up there. Maybe somebody had seen him from an apartment below and was worried... though he didn't catch any tones of fear or alarm.
Doug decided to wait where he was, and listen as well as he could, to try and pick out the words.
