“The season opens with some bombshells!” teases creator Eric Kripke, who already jolted viewers when he sent Dean Winchester (Jensen Ackles) to Hell in May’s season finale. Season 4 opens four months later, when Dean wakes up with no memory of his torment. “What happened to Dean in Hell and to [younger brother] Sam (Jared Padalecki) when he had to be a hunter by himself will slowly come to light,” Kripke says. “It gives us a nice opportunity for an internal struggle for Dean and for the brothers to surprise each other.” Katie Cassidy (Ruby) and Lauren Cohan (Bela) are both gone, but Jim Beaver and Steven Williams are back as geezer demon fighters Bobby and Rufus. Get set for a revealing flashback to the Winchester parents’ teen years, an homage to 1930s monster flicks, and a bloody Halloween show.
Traci Dinwiddie, a vivacious thirty-five year old brunette, has been cast in the guest starring role of ‘Pamela Barnes’ in the season four opener of the hit CW/ Warner Bros series Supernatural.
Pamela also just happens to be, in the words of the Winchester brother’s good friend Bobby Singer (played by Jim Beaver), ‘the best damn psychic in the state’. Pamela has been contacted by her old friend Bobby to help he and Sam Winchester (Jared Padalecki) track down demons and to possibly learn more about the fate of Dean Winchester (Jensen Ackles) who was last seen in the Supernatural season 3 finale ‘No Rest for the Wicked’ hanging by hooks pierced through his flesh after being dragged into hell by demonic hounds sent to fetch his soul in consummation of deal he had made to trade his soul for the life of his brother.
