Silo officially returns on Apple TV in 2026 with season 3, which seems to mark the end of an era for Rebecca Ferguson's Juliette. Although the final release date for Silo season 3 is yet to be announced, Rebecca Ferguson has confirmed that it will premiere sometime in the summer of this year. Her character, Juliette, too, is set to return in the show's upcoming installment, but her story will seemingly not be the same.
