The Last Problem.In a distant future, an older Princess Twilight Sparkle is visited by one of her students named Luster Dawn, who does not understand the importance of friendship. Princess Twilight tells her a story of how she was once worried of losing her friendships. Flashing back to her coronation day, Twilight makes preparations to move back to Canterlot with Spike but is worried that this will result in her and her friends drifting apart. Twilight's friends seem more welcoming of this change however and focus more on the final preparations for her ceremony. Twilight grows frustrated and tells them that she feels like they care more about making her coronation perfect than the fact that she will be leaving Ponyville. Her friends reveal that they share her concerns and are keeping themselves busy so they won't be sad about it either. They let out their feelings and cry together, which makes Twilight feel better, knowing that her friends feel the same way. This, however, results in them getting behind on their preparations and they almost miss the train to Canterlot. Twilight makes it just in time for her coronation but the ceremony encounters many problems. After the ceremony ends, the friends share a laugh about the disaster. Twilight decides to establish a Council of Friendship so she can maintain her relationships with her friends by convening once every moon. Afterward, Celestia and Luna retire to Silver Shoals. Back in the future, Twilight finishes her story and explains to Luster Dawn that friendships can be hard to maintain, but life is even harder without them. The rest of the Mane Six enter, now older, still friends with Twilight and ruling Equestria together as the Council. Luster Dawn takes Twilight's wisdom to heart and Twilight sends Luster to Ponyville, where she begins to make friends with the other creatures there and have adventures of her own.
