Honestly, who wasn't laughing their ass off when they heard that the character who was made because of Gay Panic became a lesbian? No one, that's who.
Dick Grayson, then Nightwing hits on her in 52 and fails (for the obvious reasons). Years later, as Batman, he hits on her saying pretty much the same thing. She references the fact that she spent the entire night getting beaten up, imprisoned, trapped in a falling cave, died, resurrected in a Lazarus Pit, and then fought a fake zombie Batman. And then says the next time she wants to do that again she knows who to call, making it even funnier than her just threatening him. All with a smile on her face.
