Episode Title:
The Point of No Return.
Episode Description:
While going through a box of her old things sent by Princess Celestia, Twilight finds a library book she borrowed years ago but never returned. Accompanied by Spike, she hurries to the Canterlot Library with the intent of returning it, but finds that the old librarian, Dusty Pages, no longer works there. Both Twilight and Dusty had had perfect records in borrowing and maintaining books, respectively, and Twilight fears that the loss of this book cost Dusty her job. She and Spike track Dusty down to a retirement community and find her participating in several of its activities, but she firmly refuses to take the book or have anything to do with the library ever again. She explains that she was so worried about keeping her perfect record that she never had a chance to enjoy life; after the book went missing, she quit voluntarily and began to find happiness. Returning to Canterlot, Twilight pays the overdue fines and keeps the book as a reminder that there are more important things in life than trying to be perfect.
