Did the Joker really have a death wish? Of course she knew what he was doing. He thrived on chaos and mistakes made in the heat of the moment. Was it working? A bit. Still, she was more focused on destroying him and keeping him from releasing the toxins on the city. She really didn't care about most of the people but that didn't mean she wanted the Joker to release it. Between the children and the general wanting to beat him thing, she was determined to end this. Or find a way to end this.
Still, while she was prideful, she also knew that doing this alone might not be her best idea. As such, she pulled out her phone and sent a text to both Dick and Jason. Okay, she should have done that before, but now she had more information to give them? Yeah. That was it. Between the three of them, Joker would die. She didn't know who would be the one to do it, but he would die.
"Of course it is." This was something she had to tread carefully with. She had to keep him from unleashing the toxins until someone who could figure out the code could type it in to keep it from happening. The next trick was making sure Dick and Jason could get in. The doors were sealed but that didn't mean much. He was human after all. A pathetic excuse for a human but a human all the same, he still had to breathe. Which meant that there would still be air ducts open. Dick and Jason trained with Batman, they'd be fine. Look at her, all team player like. Yeah. That was it.
