A Desperate Mom Faces an Unthinkable Dilemma on 'Silo'

Three episodes into Season 3, Silo is no longer just about what you aren’t allowed to know. It’s about what a bunch of weirdos can decide you’re no longer allowed to remember.

Here are the big takeaways from an episode of Silo that turned memory loss into a weapon.

Remind Me Again: What, Exactly, Is a Safeguard?

That Algorithm keeps mentioning “Safeguard,” and it’s so casual and passive about it that it might be easy to forget what, exactly, a Safeguard is. Recall that Season 2 finale: Lukas Kyle plunges to the bottom of Silo 18, finds the secret tunnel, and encounters the Algorithm, the AI voice that runs this hellhole. The Algorithm warns him: keep your mouth shut about what you saw, or we hit the Safeguard button.

The Safeguard is the fail-safe. It’s a pipe on Level 14 designed to gas an entire silo’s population the moment things get out of hand. Remember in Season 2 when Juliette strolled into Silo 17 and tripped over thousands of rotting corpses? That’s what happens when you don’t keep your mouth shut. And in Episode 3, we learn that contact between two silos — digging horizontally to breach another silo — won’t result in an easy passageway for neighbors to share recipes. It merits Silo extinction.

Now, when Camille recalls that Lukas knows there are other silos out there, she puts two-and-two together and does the Home Alone face: If he’s digging sideways, he ain’t just breaking the Pact. He’s about to accidentally murder everyone in Silo 18. Uh oh.

She doesn’t want that, so she floods the mines with poison gas under the guise of “rat extermination,” giving zero warning to the miners inside and nearly suffocating Juliette. To prevent a full-blown Safeguard, Camille casually commits a light, localized massacre. (Though worth noting: Lukas briefly surfaces to rescue Juliette before vanishing again, so her horizontal-digging theory is still unconfirmed. Maybe he’s just whittling wood into Pez dispensers.)

What’s on the Mystery Cassette?

Meanwhile in the flashbacks, we learn a little bit more about the mission that broke Charlotte Keene.

At a pilot’s memorial, Congressman Daniel Keene learns that the aircraft on that doomed flight had their encrypted comms swapped out for unencrypted gear. In other words, someone wanted those transmissions intercepted, which means a tape probably exists. A-ha! Daniel and Helen Drew head into the dark web to meet a shadowy fella named Steve (but not Steve Zahn, because we still haven’t seen him this season). Steve is reluctant to help until Daniel admits Charlotte was his sister, at which point he hands over a 20-second analog cassette but warns Daniel and Helen not to listen.

They listened.

Of course, we never hear the audio because this show is mean. The camera just stays locked on their horrified faces. Whatever is on that tape is bad enough that Daniel immediately insists the public needs to hear it.

And then, because this is Silo, the show shakes its head and scoffs at us. When they return to Steve’s hideout, the place is tossed, Steve is gone, and the tape is missing. DAMNIT. The proof evaporates, leaving our D.C. crew in the exact same situation as the folks in the silo: They know they’re being lied to, but there is no proof.

Anthony Illustrates What’s at Stake

It’s easy to get lost in the show’s sci-fi lore, so the show, via Anthony, reminds us of what’s actually at stake here.

Camille Sims is probably the most compelling character this season. She’s not a villain. She’s just a desperate mom. The Algorithm is pressuring her to pump Vitamin D+ — the memory-suppressing drug Juliette has been secretly spitting out — into the silo’s entire water supply, which would wipe the entire population’s memories, including that of her and Robert’s son.

Then comes the fight with her husband, Robert. Robert wants to pull their son, Anthony, out of school for a family day. He wants the boy to have real memories of them together because Robert was affected by Juliette’s cautionary tale about losing the memory of her father. Camille, however, is like, “No memory is bad. No life is worse.”

In other words: if Camille dumps the memory-eraser into the water, what happens to Anthony? Unless the Sims family has a secret stash of Dasani, their kid forgets them. Hell, they forget each other. The drug means their child won’t even recognize their faces.

Which brings us to the episode’s devastating gut-punch: To save her son’s life from the Safeguard, Camille has to erase his memory of her. That’s a hell of a dilemma. Does Anthony keep his soul or his lungs, because he can’t have both.

Good luck with Episode 4, everyone.
