There are a total of 17 series regular cast members throughout the four seasons of Prison Break, and regardless of their roles, only two were never jailed, Veronica Donovan and Sofia Lugo, though the pair weren't given easy times throughout the series. Both of the women were held hostage at least once, with Veronica being killed off after discovering Terrence Steadman's crucial secret, while Sofia is captured by Gretchen in Season 3, though she survived the entire series, and came out of the ordeal relatively unscathed compared to the other regulars.
