Supernatural: Hunted

Having discovered that his dad warned Dean that if he couldn't save Sam he'd have to kill him, Sam parts company with Dean to try and find more "gifted children" like himself.

With the assistance of Ash at Ellen's Roadhouse (we also learn that Jo has now taken to hunting full-time), Sam heads off to Illinois to investigate the recent murder of a young man with the same profile as himself.

Sam, in turn, is approached by a very cute woman, Ava (Katharine Isabelle), who has had dreams predicting Sam's death.

The couple are ambushed in a motel by none other than overzealous hunter Gordon (from Bloodlust) who has learned of the extraordinary abilities of Sam and people like him - and was responsible for the earlier murder that attracted Sam to this place originally.

Luckily Dean has tracked Sam - with Ellen's help - and tussles with Gordon, but is overpowered, captured and used as bait to lure Sam into the trap that Ava dreamed about.

Although lacking any paranormal monsters, Hunted is pure Supernatural for its continued examination of the attitudes of hunters, revelations about the Yellow-Eyed Demon's plans to use this band of psychics as foot soldiers in a coming war, and Dean's growing disillusionment with the life they are leading (almost certainly sparked by the knowledge that he might have to kill his own brother if Sam goes "dark side").

As the second season of Supernatural races towards the half-way mark, we can see all the pieces being moved into position - but still no idea how the game will unfold... and that's what makes this programme so involving and exciting.
