“Twilight Sparkle, you are forbidden from returning home until your performance improves.”
 
“With the return of Nightmare Moon fast approaching, Princess Celestia is forced to accelerate filly Twilight’s magic training beyond the capability of any pony, let alone Twilight who is still just a filly.
 
Filly Twilight’s blissful days with caring Celestia effectively end. Celestia becomes harsh and cold, callously berates Twilight for the slightest error, and doesn’t acknowledge any success. Twilight’s enduring successes only prompt Celestia to accelerate her education further until Twilight’s efforts fall short.
 
Upon Twilight’s first failure Celestia forbids Twilight any form of distraction, ripping away her stuffed toy Smarty Pants, and finally forbidding Twilight from visiting her parents.”
