Re: Riddler/Batgirl
[Simply.] I like that. [Blink. Blink.] Sometimes I poke fun at you or your family. Or I tell a dirty joke. And, you press your lips together to fight off a smirk, but it wiggles at the end of your mouth. Then you say something like "That's disgusting, Nigma!" or "Rude" and your eyes turn bright, bright blue.
Not that kind of magic, smartass.
What'd you tell him? That you're playing a long game of tag with me? [...] Don't push it, Batgirl. I'm an unpredictable man.
