Robert Knepper discusses the return of his role in 'Prison Break'

For four years on 'Prison Break’, Robert Knepper played the most despicable inmate on the show, Theodore Bagwell - better known as ‘T-Bag’. The show is back - so is T-Bag, and in tonight’s premiere, T-Bag shares a piece of mail that makes him wonder whether someone who was thought dead is really alive. ‘Prison Break’ airs Tuesday night at 9:00pm - right here on FOX.
