Silo season 3 premieres next week on Apple TV (watch here), with three major changes coming that have been highlighted in the season’s marketing. Spoilers ahead, but only those Apple has already revealed.

#1: Split-timeline plot will explore the world pre-silos

Silo is based on a trilogy of novels by Hugh Howey. Seasons 1 and 2 both covered only the first book. But rather than moving directly to book 2 in season 3, Silo’s next two seasons will interweave events from books 2 and 3.

That’s because book 2 takes place primarily in the past, exploring the origins of the silos. Whereas book 3 focuses on Juliette and the rest of the characters we already know.

So unlike Silo’s first two seasons, season 3 won’t be stuck in the drab, dark environment of the silos. Instead, much of it will take place out in the world before the silos even existed.

#2: Major new cast additions

Because the “before times” storyline will be a significant focus of Silo season 3, there are a variety of major cast additions joining the show.

Two key new roles will be filled by Jessica Henwick and Ashley Zukerman, whose characters we got a glimpse at in season 2’s finale. Per Apple’s season summary:

Meanwhile, in the “Before Times,” journalist Helen Drew (Jessica Henwick) and Congressman Daniel Keene (Ashley Zukerman) uncover a conspiracy that pulls them into a chain of events with catastrophic, irreversible consequences.

Additional new cast members include Laura Innes, Jessica Brown Findlay, Morven Christie, Reed Birney, Matt Craven, and Colin Hanks.

#3: Juliette’s new role

Juliette takes on a new mantle in season 3, as revealed by Apple through an exclusive Rotten Tomatoes teaser clip last month.

In season 3, the silo has a new mayor: Juliette Nichols.

Season 2 ended with Juliette and the current mayor, Bernard, struggling in the silo’s airlock as flames threaten their lives. I guess we know who survived.


You can watch Silo seasons 1-2 here on Apple TV.

Apple TV is available for $12.99 per month, or you can get it discounted through the Apple One bundle.
