With Princess Flurry Heart around, the royal family has been all smiles for what seems like forever. One day during a visit to Ponyville, Princess Cadance wants to talk to Twilight Sparkle in private about something. Twilight happily obliges, but what she hears threatens to shatter her world as she has to choose between trusting one of her best friends and something of an older sister to her in Cadance, or her B.B.B.F.F. who's known her for her entire life, Shining Armour.

Will the royal family be able to pull through as their deepest secrets are revealed?
