EPISODE RECAP
Sheriff Holston Becker is sent out to clean the Silo's sensors in a traditional ceremony, but instead of completing his task, he removes his helmet and dies in the toxic outside world after crawling to his deceased wife's body, while the Silo's population watches in shock. Meanwhile, Deputy Marnes discovers that Holston left a letter suggesting Juliette, a young engineer, as his successor, and Mayor Jahns becomes concerned that sending out a Sheriff to clean may have triggered a previous rebellion. Juliette confides to Martha Walker that she suspects her boyfriend George Wilkins was murdered rather than a suicide, and after investigating with Holston, she discovers that George had found evidence related to the Silo's origins hidden in deep tunnels, leading her to descend into unexplored depths of the facility after Holston vanishes.
