Sunset Shimmer, personal student of Princess Celestia, is the most gifted Unicorn in Equestria. She has long-neglected personal connections in favor of studying and ambition. Celestia, concerned by her student's behavior, searches for a way to help her student grow as a pony. As a last resort, her thoughts turn to Starswirl's Magic Mirror, that it could show Sunset a new way, or to a path of darkness, but then something or rather somepony comes as her solution. Sunset now finds herself teaching her own student, a bookish and anti-social young Unicorn named Twilight Sparkle. Can the two form an actual connection, or will their anti-social tendencies lead to disaster?

(A What if scenario where instead of showing Sunset Shimmer the Magic Mirror Celestia brings Twilight Sparkle to her to teach)
