Ever since her affair with Ed Bauer, Lillian has done nothing but age gracefully. When Lillian learned of Harley and Phillip's relationship, she called Beth, who returned to Springfield. Lillian then spent most of her time trying to keep Beth from acting crazy and trying to get Phillip back. When Beth's scary ex-boyfriend turned up in Springfield, Lillian freaked and hired a man named J.C. Clayton to scare Carl out of town, but she may be responsible for getting Carl killed in her attempts to protect Beth.
