Fun for the Joker, perhaps. Fun for Ivy? Definitely not. And it wasn't like she could tell the birds to hurry up or anything as she couldn't exactly move or reach her phone. Well, they had the message and would come. If anything, Jason would. He had a personal grudge to settle with the Joker and well, Dick was Batman's little protege. They knew the risks. And hopefully someone would be able to figure out the code for the Joker Venom. Harley most likely did but she didn't know where she was. Had she seen the note? Okay, maybe she should have slid the note under the door to Sam and Ruby's room to keep Harley from getting a reckless idea. Dammit, she better not show up...
But then she was being cut on just enough for the wounds to sting and oh did they sting. Beyond her breathing hitching though, she gave no sign of pain and instead set a glare on Joker, spitting in his face.
"If by corrupt you mean I made her realize she deserves better than a psychotic bastard like you, yes, I did. And I'll do it again. I'm keeping her safe which is more than I can say you ever did."
Yes, she was playing into his hand, talking when she shouldn't. But she was beyond angry with him and she refused to let him think he could get away with being an abusive bastard just because he was psychotic. It was sickening.
