As a result, she revokes holding back an old punishment she had for Twilight Sparkle and places the blame on Applejack, Rarity, Fluttershy, and Pinkie Pie as well. While serving their time doing community service for the stuck-up sophisticated ponies of Canterlot, their track records are all smashed to pieces and Ponyville steadily falls into disarray. As Rainbow Dash mourns over being lonely, she remembers a promise she made to a friend - to become like a big sister somepony always wanted. Having someone to confide in makes all the difference.
