With only one episode remaining, the penultimate chapter of Silo season three is effectively split into two halves, each taking place centuries apart but ending in much the same way: with an enormous explosion.<\/p>\n
The first stays largely inside Silo 18, where Bernard Holland (Tim Robbins) makes the ultimate sacrifice as Juliette Nichols (Rebecca Ferguson) and her allies attempt to stop The Safeguard, the mechanism capable of wiping out Silo 18’s entire population. The second returns to the Before Times<\/a>, where the underground project<\/a> is nearing completion and an increasingly uneasy Daniel Keene (Ashley Zukerman) and Helen Drew (Jessica Henwick) discover just how quickly their world can change.<\/p>\n Together, they make episode nine one of the season’s most consequential \u2013 and unsettling \u2013 instalments yet.<\/p>\n Inside Silo 18, Bernard comes face to face with The Algorithm<\/a> and Camille Sims (Alexandria Riley), apparently hoping to negotiate a deal to crack down a growing unrest.<\/p>\n His efforts fail, but it soon becomes apparent that Bernard only wanted to provoke The Algorithm in an attempt to test its responses, leading him towards a startling theory: the mysterious intelligence controlling so much of life inside the silos may actually have a human voice behind it.<\/p>\n Knowing the operation needs a distraction, Bernard volunteers to go outside and clean, one of Silo’s most important rituals in which almost everyone ultimately succumbs to the toxic environment outside.<\/p>\n Camille and Robert Sims (Common), meanwhile, finally confront the division between them<\/a>. Despite finding themselves on opposing sides, both insist their decisions are motivated by a desire to protect their son. Robert refuses to allow his son’s memories to be erased, while Camille believes forgetting may be essential if he is to survive inside the silo.<\/p>\n But Bernard’s sacrifice has served another purpose.<\/p>\n As Silo 18 watches him take his final steps outside, enormous explosions suddenly reverberate through the bunker. Camille realises Juliette’s allies have used the distraction exactly as intended, continuing their mission against The Safeguard while everyone’s attention was fixed on Bernard.<\/p>\n
