Nadia Winchester has had her work cut out for her since she was a toddler; with Dean Winchester as her older brother and Sam as her younger, she was sandwiched between chaos. Growing up as a hunter-especially as the only girl-was not exactly an ideal upbringing, but it made Nadia who she was. When their father, John Winchester, goes missing on a hunt and doesn't reach out for weeks, Nadia and Dean seek out their younger brother - the same younger brother that they hadn't seen in two years. In doing so, that day sets of a whole chain of events, changing the lives of the Winchester siblings forever.
