Applejack has had a secret crush. Not only that, she has another secret know to only her family. When Twilight was nearly raped because an old classmate was acting on false rumors from school, Applejack comes to comfort her friend. In doing so, the apple brandy (not AJ’s cousin) AJ brought to calm Twilight down allows Twilight to confess her deepest secret to Starlight Glimmer. But Starlight Glimmer is a lavender Unicorn, not the orange Earth Pony there with her.
A comedy of errors will fulfill four pony’s dreams.
Secrets can not always be kept secret.
Oh, and can you believe Princess Twilight Sparkle knew those words?
The sex label if for implied, not actual graphic. However, the attempted rape scene could be disturbing to some.
