All it takes is one action to change the paths of reality. All it takes is a moment of hesitation to create a catastrophe. All it takes is one single thought... to turn you over to darkness and then that darkness will begin to overwhelm you.

Diamond Tiara can't forgive herself over her previous actions before being reformed. She can even less understand why the pony she personally tormented came to her aid. It's time to find the truth!

Starlight glimmer gets mad at Twilight once she realizes she's used mental magic more than once. Karma really does stink doesn't it?

When Rarity and Twilight first met Rarity asked Twilight what she though of Canterlot. What if Canterlot was worse than it originally was in the show? What if Twilight carried some mental scars?
