Each time Twilight tries to stop Starlight, she fails and is flung to a new, twisted Equestria, each one worse than the one before, until she lands in one that isn't worse. The only real difference is that her castle isn't there. But the library is.
After psyching herself up, Twilight asks Applejack out on a date. Everything's going well until an obscure form of unicorn magic interrupts and makes things really awkward.
Some questions have easy answers. Why Applejack never revealed her feelings for Twilight was a question like that. However, some questions are more difficult to answer than they first appear.
Twilight's plans for a sleepover are tested when most of her guests have to cancel, but Applejack convinces her they can have fun together with just each other's company.
