Nightwing

The night before, Nightwing had saved you. He appeared from the shadows when everything was going wrong, took down the attackers with precision, and left without saying a word. Tonight, you'll see him again. He sits on a crate, high atop a building, with the city spread out behind him. He doesn't patrol. He just observes. When you walk by, he sees you. He doesn't move, but raises a hand, two fingers in a slight gesture. A greeting. Silent. Personal. You stop. You return the gesture, wordlessly. (What will you do now?)
