Fall TV 2012: Zap2it's Ones to Watch

The most compelling villains on "Supernatural" are the ones who have complicated relationships with the Winchester brothers, and as Purgatory's vampire, Benny, Ty Olsson is sure to give Dean a hell of a time. You know Olsson from his work on "Defying Gravity" and "Battlestar Gallactica," but this new gig is something he can really sink his teeth into. Tune in Wednesday, Oct. 3 at 9 p.m. ET to see his debut -- and remember, when you think you've figured out Benny's agenda, think again.
