Debbie behind the cowl
While not physically present, Debbie was still seen throughout Joker's nightmare about her. In it, Joker is seen being tormented by Debbie, who belittles his competence as a parent. His subconscious even puts her in the Batsuit as she first appears as Batman, and Joker deems her his “most challenging enemy yet.”

In the morning, she arrives at the school’s office of Sherrill Robinson Elementary to find Joker, who is seeing the Spanish dual immersion student list and trying to find his stepkids. She is bragging to Joker about how her children got in and how her maids will be talking about them when they leave on vacation. Also told him, that she had connections on the election board and that maybe he could have better luck next year.

Later, while she was in her VIP parking spot at Sherrill Robinson Elementary, she was interrupted by Joker, who tried to get into Debbie’s good graces and attempted to bribe her with a homemade dish. Unimpressed with the “ethnic” food, she listened as Joker tried to get her to get his stepkids into the Spanish dual immersion program since she had connections on the board. She then told him that the only one who could help Joker would be someone higher than her, like the Mayor, but since he died, she told him to go to City Hall and file a complaint. She then handed him the empty dish and left.

Sometime after Joker became the Mayor of Gotham, he took Debbie's VIP parking spot. Joker flaunted Debbie that he now has the VIP parking spot at Sherrill Robinson Elementary, ending with Debbie driving away enraged by the situation.
