Nightmare rolled her eyes, "Here we go. Rarity, I'm not what you think I am, and while I do bear a passing resemblance to Nightmare Moon, I am not her. I don't want to hurt anypony, or rule Equestria, or to plunge the world into eternal night. I just want to be free to live my life. I'm also trying to help you, so a little less hostility on your part would be appreciated, especially after I had you fed."
