“Bitten” is the rare episode where the focus is actually directed away from the Winchester brothers. Instead, the episode is made up mostly of “found footage,” featuring guest stars Leigh Parker, Brandon W. Jones, and Britni Sheridan as students investigating inexplicable animal attacks in their college town. Obviously, they aren’t just animal attacks.
“You’re living in this found footage, the boys bracketed on either side, in the opening and at the very end,” executive producer Bob Singer told Zap2it . “But for 95 percent of the show, you’re living in this found footage. [The Winchesters] are in it unknowingly, so it’s crazy. It’s a really good episode, very compelling, and has great guest stars. It deals with college kids.”
