Several years later, Mrs. Millbrook is trying to convince her daughter that there is still a chance for Daphne to walk again, but Daphne refuses to listen. Once Mrs. Millbrook is diagnosed with cancer, she stops trying to convince her daughter that there is still hope.
On the day of her death, Mrs. Millbrook has an argument with her daughter. The argument ends with Mr. Millbrook sending Daphne to her room. When Daphne returns to the room that her mother is in, Daphne finds her mother dead in her father's arms.

Mrs. Millbrook tries again to convince her daughter that she is special and that she should not let anything hold her back. Daphne does not believe what her mother is telling her, but her mother tells Daphne to stand up and leave this cage. Daphne concedes and stand up, only to realize that she no longer needs her leg braces. Soon after, Daphne runs off.
After the funeral, the Millbrooks are visited by Thompson. Once Thompson has left, Daphne gets into an argument with her father. During the argument, Daphne tells her father that she wishes that he had died instead of her mother.
