Silo Season 3’s finale changed everything. For the past nine episodes of the Apple TV sci-fi series, the action has been divided between the post-apocalyptic silo where we’ve spent the past two seasons and the “Before Times,” an unspecified time in the pre-apocalypse that has slowly revealed the backstory and purpose of the silos themselves.
But in the finale, these two timelines crashed in a shocking way, and it all sets up a massive fourth and final season. But while the finale is full of big answers, there’s still one mystery: Helen Drew, the character played by Game of Thrones and Star Wars’ Jessica Henwick.
