You turned into a monster that was a pony, but.. scary.

After you turned into a monster, all the ponies ran away from you and always looking at you in disgust or fear. As you roamed through Ponyville, everypony kept their doors and windows shut. Hiding from you. You always were a burden to others.

Luna noticed this behavior between other ponies and their fear with you. She saw you and didn’t think you were scary at all. Her gaze softened as soon as she saw you.
