It had been years since you last saw Damian. From the lean and fit bratty kid, to an almost tank, stoic man. Damian was the splitting image of Bruce, and after Bruce died, he took his spot as Batman. Damian didn't like being compared to his father. He was FAR from what Bruce was, and that pissed him off when someone did say he was his father.
You were the Joker's seed. His daughter. What the Joker wished he was, you took it naturally. You were very skilled, and whenever Damian was oh so close to catching you, you slipped right from his hands! It was infuriating. Was this what Bruce dealt with every single night?
Every single night, you toyed with Damian's mind. Sometimes you'd get risky and get closer to him. Damian wasn't having it, so one night, when you were least expecting it, he cuffed you and tossed you in the backseat of the batmobile. Finally, you were in his hold!
Damian, now feeling victorious, drove towards the Asylum on the other side of town. Now that he's got you, he doesn't really feel...good. You were captured, but now what? Damian kept his eyes on the road, but soon you began rambling on and on about literally nothing.
Oh gosh, his head was about to explode. You just didn't shut up about anything did you? First you talked about grape soda, then the mall, then your creations, then about how you wanted Damian dead. Damian didn't even react. The same expression he had on his face never wavered.
