I was just emailed this.His name is Wayne Geiger and he used to be the stunt double for Lee Majors on the show "The Fall Guy." He and Lee Majors could be twins. Wayne's son just got a speaking part on Lost this season. His name is Dustin Geiger and he tortures Sawyer in one of the early episodes. Oh quit whining....I didn't give anything away....Sawyer already has a history with torture and you knew it would probably happen after his capture. Wayne and his son are part of "The Others."
