Savannah shares updates on their appeal, including new details following her efforts as a prison reform advocate. The 26yearold also opens up about being a 'bonus parent' to her brother, 17yearold Grayson, and sister, 10yearold Chloe, whom she hoped to inspire by taking part in the physically grueling competition series. Season 2 of 'Special Forces: World's Toughest Test' premieres Sept. 25 on Fox. New episodes of Savannah's 'Unlocked' podcast drop every Tuesday on all major platforms.
