About me: Isabella Nicolette Winchester, is the twin sister of Sam and younger sister of Dean. She is a trained hunter much like her older brothers but they hate the fact she is a hunter. She can hold her own much better than them, plus she is the brains of the twins. She can outwit most of the creatures they hunt. Izzy never got along with Jo since she couldn't stand the girl for being disrespectful to Ellen whom she looked up to as a mother figure since their mother passed when she and Sam were babies.
