Twilight had made her choices. She had decided to draw a line for her actions and never cross it again. But how long can she stop herself if there's no one else there to stop her? How long can she stop herself when there's someone who wants her to cross that line, a voice she can't ignore that tells her to go back to what she once was?

This story takes place in the same universe as Wintermist's "Friendship is Mind Control: Consequences".
