Celestia knows Nightmare Moon is returning. She can't bring herself to face her.

Nightmare Moon returned to Equestria, and now sits and contemplates her existence.

Luna's mind is fractured, broken. If she is going to return as a princess of Equestria, she needs time to heal, as much as she can. But who is going to help her heal, and who will she be at the end of it all?

Sunset Shimmer finally tells Twilight about her depression.

Sunset knows how hard it can be to have a life altering change thrust upon you. She wants to help Twilight through hers.

Sometimes pain is preferable to emptiness.

Laughing takes a lot of energy. Energy Sunset doesn't have. She hopes her friends don't notice.

Less than a week after the fall formal, Sunset gets called in to the principals office. Again. If only she knew what she did wrong this time.

More than three hundred years after becoming a princess, Twilight looks back at her long life.

Princess Twilight needs glasses. She's only now finding out after meeting her human counterpart.

Sunset has one left apology to give. She was horrible to Flash while they dated. She doesn't expect it, but all she wants now is to be forgiven and move on.

What does Death do with a dead android?

Applejack asks Sunset what happened with the other Sunset. The answer is a lot worse than any of them expected.

Discord can be a huge dick. And that's not even half of it.

Twilight touched upon powers far beyond what any mortal should have. So Celestia had to ensure it never happens again. Twilight didn't take kindly to that.
