She displayed visible anger after entering an apartment and seeing the latest victims of the Joker's terrorist regime. She retaliates at Batman, saying, "Us contaminate it (the crime scene)? It's because of you these men are dead!"

It is clear she had no love for Batman after what happened but she appears at the Bat-Signal and is present when the spotlight is reluctantly destroyed by Commissioner Gordon.

Anna was heard various times in the movie commenting on her mother who was in a hospital. Towards the end of the film, Anna was ordered to trick Gordon's wife into taking her children to 250 52nd street, by Harvey Dent as Two-Face. Two-Face was furious how she was corrupted by Sal Maroni, along with the late Michael Wuertz, whom he had earlier shot. She claimed that she was forced to work for Maroni, due to money in order to pay her mother's hospital bills. As Dent flipped his coin, it landed normal side up. Anna was spared her life and was just knocked into unconsciousness.
