For five years the Winchester brothers have been embroiled in the desperate search to find their father and the truth about their mother’s death. Sam and Dean have delved deeper into the supernatural world than they ever thought possible. Sam’s prophetic dreams have developed into an ever-present psychic power; he can now read minds and has premonitions even when awake. Dean, after an unusual encounter with a minotaur during which he was bitten, was gifted with the half-bull, half-man’s supernatural strength. The cases they have been on get exponentially more complicated, however, and even with these new gifts they are having a more and more difficult time.

Finally realizing that they need help, they turn to a lot of the teens they have saved over the years, some with their own supernatural gifts, some not. Cassie, Dean’s ex-girlfriend (Route 666 Episode) is the first on their list of contacts. She reluctantly agrees to come, hoping to somehow salvage things with Dean. Since her experiences with the paranormal, she became a munitions expert and sharpshooter. Next are the Collins, Hailey, Tommy, and Ben (Wendigo Episode.) Since their time with the Winchesters, Ben has developed a strong empathic ability. Tommy and Hailey have become trained, talented martial arts experts, determined to protect themselves and their brother if anything like the Wendigo happens to them again. They are eager to come with Sam and Dean, hoping to help others as they themselves were helped.

The brothers receive a call from Lori (Hook Episode) after she graduates from college, earning two Masters in Paranormal Science and Psychology. She agrees to join them as their paranormal expert. Drew, a distant relation of Max Miller (Nightmare Episode,) panics when he begins developing a telekinetic ability even stronger than that of his third cousin. His great-aunt calls Sam and Dean, who come to calm Drew and end up taking him with them.

Charlie’s (Bloody Mary Episode) senses, starting with her eyesight, became more and more acute over the past five years. She now has the sight of an eagle, the nose of a wolf, and the hearing of a bat. Charlie also now can move with the speed and graceful fluidity of a cat. Having long since informed the brothers of these new abilities, they recruit her to be on their team.

Finally there is Aggie, a white witch they met on the road about three years ago. She comes along as their magical aide, knowing a variety of spells and potions to drive demons and creatures away.
