Applebloom is faced with horrible depression. She doesn't want to go on…and it scares the Apple family. Then, Applejack's twin sister Applecore (who was separated from her at birth) finally comes back from staying with Uncle Apple Strudel. Applecore finally gets to see Applebloom, and she hasn't seen her for eight years. But when Applebloom does something to herself, Applecore has pressured herself into telling her something she never knew. Applebloom's already been through enough, can she handle what her "sister" is going to tell her?
