Uma and Cynthia are able to escape Beth as she encounters Priscilla. Priscilla is able to injure Beth but sensing her danger Alicia came to help her sister. Alicia awakened and helped Beth kill Priscilla. But Priscilla was too powerful and decapitated Alicia. Seeing this made Beth go into a mindless rampage to avenge her sister.
