After running a bit the Joker was able to reach nora's room he knocked out the guards and broke inside. He then closed and locked the doors behind him and Harley. He then took out a radio he'd gotten from the guard and said "Mr.frozen if you hear this then I have your wifie nora. if you don't break out now and make it to the control room she dies. Also to any guards who even think about coming in here I have this rigged to blow." He then began working on the small bomb for the door. After a few minutes he was able to make one and place on the door. He turned to harley and said "Alright, You take that vent to the inmates here release them I need to make sure Freeze guy does what I ask." He then went through the vent on the right and began crawling through it.
