Mrs. Harris and her family were shown to have owed a large debt to the bank, forcing them to put more money towards that then food, evidence being her daughter saying "Mommy, I'm hungry", and Mrs. Harris tells the her daughter that she is as well. She was seen only in two scenes, one in which she was standing outside of the Kingston Falls bank, begging Mrs. Ruby Deagle for mercy so that her family could get more time to pay off their debt to her. The family were in such a large debt, that her husband Joe had to leave the town to find work. Deagle refused, however, and when Mrs. Harris told Mrs. Deagle that it was Christmas, the cruel woman turned to her and her children and said, "Well, now you know what to ask Santa for, don't you?" Mrs. Harris was then seen speaking to Mr. Corben about it, although he also refused, much to her dismay.
Mrs. Harris and her family most likely survived the Gremlin attack on Kingston Falls like most of it's resident's did. it's also likely that with Mrs. Deagle and Corben being killed by the Gremlins and Gerald Hopkins losing his sanity during the attack and probably being institutionalised, that the bank received new (and less corrupt) management. This means that Mrs. Harris and her husband were able to pay off their debts and secure a better future for them and their children
