"Supernatural" October 22 episode called "Live Free or Twi-hard" will take a jab at fellow CW series "The Vampire Diaries" and popular vampire movie "Twilight". The show finally picks up vampires as the supernatural creature that Dean and Sam would face. Unfortunately, one of them gets beaten and turns into one.

After a group of young girls go missing, Sam and Dean realize that a group of vampires have taken up residence in the small town. After a fight with two of the blood-suckers, Dean is bitten and turns into a vampire. Samuel tells Dean he can change him back but he'd have to get the blood of the vampire who turned him. Dean infiltrates the nest and runs into the Alpha.

Executive producer Sera Gamble assured fans of "Diaries" that the episode will not give a direct jab. "I don't think there's currently a [Vampire Diaries] mention in the episode," Gamble told EW. "But part of the thing is finding a balance between, say, [showing] a poster from the actual show and having Sam and Dean really speak their minds. We don't want to offend."

On why they pick vampires, Gamble explained, "There's never been a better time to be vampire because victims just fling themselves at you, because they're like 'Twilight' fans." One thing which would be different from the "Twilight" version is the fact that the fanged creatures don't glow in the light.

"Vampires are very vicious and kind of ugly and brutal on our show," Gamble told Zap2It. "So they're taking advantage of the fact that girls kind of want Edward Cullen or the brothers on 'The Vampire Diaries'."
