Season 4 Prison Break Cast -

The supporting ensemble, however, is where Season 4 both shines and stumbles. Robert Knepper’s Theodore “T-Bag” Bagwell, a masterclass in charismatic evil, is given his most complex arc. Stripped of his usual power and forced into servitude under the sadistic Company operative Gretchen (Jodi Lyn O’Keefe), Knepper delivers a performance that is almost tragic, showing flashes of vulnerability beneath the reptilian cunning. Conversely, William Fichtner’s Agent Alexander Mahone, once Michael’s brilliant nemesis, is reduced to a brooding sidekick.
