Twilight was a loner for basically her entire life. She did know her parents, or she thought she did, but during Leafbare when she was five moons old they left her to fend for herself so they would have one less mouth to feed. She was heart broken because they had been the only cats she trusted, but decided that she was better off alone. She put her past behind her and never looked back. Ever sence then she has sworn to be a loner and never trust anyone and if she saw her parents one day, show them her life was better without them.
