Judith works for the bank to which Buster owes a large amount of money. She calls the theater to speak with Buster but his constant avoidance of her calls inevitably led her to see him in person and threaten him to pay his debts or the bank would repossess the theater property.
After the theater is destroyed, she is seen setting up a sign declaring the theater (or rather the address where it stood) was bank property.
After Buster and his friends threw together a makeshift theater for them to perform, Judith arrived, interrupting Ash's performance and declaring Buster, his friends, including the audience, were trespassing on bank property, and demanded they leave.
Ash refused to oblige and carried on with her performance, Judith angrily threatening her intent to call the police, but the audience, riled up by Ash's performance, made it difficult for Judith to leave, and she wound up getting pierced by some of Ash's quills.
She later accepts Nana Noodleman's purchase of the property, and attends the grand-reopening of the theater.
