Last week, Silo Season 3 delivered its most shocking episode so far. But now, with the finale, Graham Yost's adaptation of Hugh Howey's book series may have outdone itself.A lot happens in the closing episode of Season 3, which knits our post-apocalyptic silos of the present day with the flashback storyline that's followed congressman Daniel Keene (Ashley Zukerman) and journalist Helen Drew (Jessica Henwick). The main thing we're left with? Questions. Many, many questions.From the ominous goings-on in Silo 1 to terminology like "The Project" and "The Directive," we've done our best to unpack everything below.

What happens in Silo Season 3's finale?First, a recap. After Season 3, episode 9 showed us the start of the apocalypse — a nuclear explosion on the launch day of the silo project masterminded by Per Stensen (Colin Hanks) and Senator Thurman (Laura Innes) — that sends Daniel and Helen running towards Silo 1 and Silo 18, respectively. We know that event took place hundreds of years before the present-day silos, but the finale opens with another shock: Daniel is still alive. Like other key members of Silo 1, he's been cryogenically frozen, woken only to deal with major security incidents around the silo complex. Now a specialist known as Troy, he seems like a different person, listening to a briefing from (also still-alive) psychologist Victor (Matt Craven) before ordering the killing of Silo 17's rebels with disturbing detachment.His sister Charles (Jessica Brown Findlay) is alive too. She's now known as Susan, and she is a senior drone commander who Daniel/Troy appears not to recognise. Clearly, his memory has been wiped, but he still has flashes of Helen, even though he no longer knows who she is. Before he goes back into cryogenic sleep, he asks Victor about her. The doctor promises to look into it and give Daniel/Troy an answer when he next wakes up. But when he puts the note in Troy's file, we see many other notes just like it.Back in Silo 18, Juliette (Rebecca Ferguson) and her allies do their best to clamp the pipe that's used to deliver the "safeguard" (i.e. poisonous gas) to the silo, while Camille (Alexandria Riley) attempts to negotiate with the algorithm to stop their silo from being poisoned. Here, we finally learn that the algorithm's voice is actually that of Victor back in Silo 1, which answers a question that's been hanging over the show since the end of Season 2.Thankfully, Silo 1's attempt to safeguard Silo 18 doesn't work. Camille deceives the algorithm/Victor and switches sides, giving Knox (Shane McRae) and Shirley (Remmie Milner) time to clamp the pipe. Victor orders Daniel/Troy to be woken back up and then dies by suicide, leaving him a video recording to tell him that the name of the woman he's been glimpsing when he wakes from cryogenic sleep is Helen Drew.Finally, back in Silo 18, Juliette visits the pipe at the very bottom of the silo and speaks with the algorithm, now voiced by Daniel/Troy. He tells her that if they make no attempt to contact other silos, Silo 1 will stop trying to kill them. She agrees.What will happen next in Season 4?We have many questions, but what comes next feels like the most pressing one. Something that seems pretty certain, though, is that Season 4 will focus on the people of Silo 18 going up against Silo 1.
