She lives just outside of Ponyville close to one of the apple orchards and started taking care of the plants when Applejack got too busy with Ministry work. She has a huge crush on Applejack because when they were in school together, Applejack defended her from bullies. It's very much an unrequited crush, but she accepts this.
When everything went down she did her best to help as many ponies as she could into Stable 02. She herself did not get in, but she died happily because she got to help many others.
