Corey Rudzinski, an online whistleblower, accused Claire's sister of killing innocent civilians, while being deployed in the army. Claire and Corey made a deal. Corey agreed to release incriminating footage of Maya without audio, and in exchange, Claire provided information about her employer, Burkett Global Enterprises, to Corey. Corey contacted Claire's secret phone by calling her from Player One Arcade Club.

Later, Claire was murdered. She was shot in the head during a robbery at her home. Several months after Claire's murder, Joe was shot and killed.

When Claire was young, she was impregnated by her boyfriend, Alexander Dosman. She kept the pregnancy a secret from Alexander and gave her son, Louis, up for adoption. Claire later married Eddie Walker and had two children with him, Abby and Dan.
