//Another year later, Cathy and Chris, who have entered puberty, have taken a parental role with the twins, who no longer remember Corrine. The twins have stopped growing due to the stress of being imprisoned and the lack of sunlight and fresh air. One day, Chris walks in on Cathy naked and is entranced. Olivia catches them and orders Chris to cut off Cathy's hair as punishment or all four children will not receive food. They refuse, but one night, Olivia drugs Cathy in her sleep and pours tar into her hair. Chris removes the tar, but Cathy futilely cuts off some of her hair in hopes of getting food for the twins. //
