Twilight Sparkle  failed her test, and Crystal Empire was taken over by evil King Sombra. She managed to escape from her stone prison, but has to return to Canterlot to face the fact the she won’t get A from her test. Neither will she get B.
(Oh, and her friends and whole world is screwed, but that’s not important.)

**WARNING: may contain some butthurt about crappy 3 season **
