Saving People, Hunting Things

Sam and Dean have been hunting for as long as he can remember. His father figure, Bobby, has an adopted daughter, Gwyneth Baise/Singer, that has been with him since she was about a year old. She has known the boys and she even became a hunter. Sometimes Bobby lets her go on cases with them if they promise to keep her safe. Her best friend is Adelaide Shade, who is a hunter as well. John Winchester and David Shade, Addi's father, have been friends for a long time. Sometimes they would work together on cases. Now that the girls are older they go on cases with the brothers most of the time. This is the story of their life.
This story is mostly based off of Supernatural but it will contain a small amount Sherlock and an even smaller amount of Doctor who.
