The Intriguing Connection Between Silo’s Heat Tape and Juliette’s Fateful Season 1 Destiny Unveiled!

Warning: This article contains spoilers for Silo, season 1 of Apple TV+. The finale of Silo season 1 heavily focuses on the heat tape, which has been subtly important to Juliette's storyline since the early episodes. In episode 10, Juliette tries to avoid being caught by law enforcement by sneaking through the laundry hatch. Unfortunately, Bernard discovers her plan and seizes her hard drive, destroying any evidence of George Wilkins' video. In an attempt to justify his actions, Bernard takes Juliette to the Judicial's CCTV room and shows her how George Wilkins sacrificed his life for the greater good.

In the final moments of Silo season 1, as Juliette prepares to leave the Silo, she receives a note from Martha that reads: "You wanted the truth. The truth is I love you. Have no fear. They're good in Supply." Initially confused by Martha's message, everything becomes clear to Juliette as she steps out of the Silo and survives. Looking at the heat tape around her wrists, she realizes that her fate within the Silo had been predetermined for a long time.

Silo Finally Explains Why Cleaners Die When Going Outside

In the finale of Silo season 1, Martha visits her old friend Carla, who works in the Supply department. Martha is aware that the Silo's IT department uses low-quality heat tape to seal the cleaners' suits. Wanting to ensure Juliette's survival, Martha convinces Carla to use a higher-quality heat tape on Juliette's suit. This change in tape is the reason why Juliette is able to survive outside the Silo and avoids the fate of other cleaners who perished within minutes.

This revelation also highlights that the previous cleaners who ventured outside the Silo only survived for a few minutes due to the low-grade heat tape on their suits. The tape quickly deteriorates, allowing toxic gases from the outside environment to seep in. The intentional use of low-grade tape by the Silo's IT department is aimed at granting the cleaners enough time to clean the Silo's screens while preventing them from further exploration. The significance of the heat tape is unveiled in the finale of Silo season 1, although it had been subtly hinted at in earlier episodes of the show.

The Importance Of Heat Tape In Silo's Ending Was Foreshadowed All Season

In the initial episodes of Silo, Juliette became the new Sheriff following Holston's death. During this time, Bernard continuously accused her of stealing a specific tape from the IT department. Juliette later expressed her dissatisfaction with the tape, stating that its quality was poor as it quickly deteriorated and rendered it useless in the Silo's Mechanical area. These early mentions of the tape establish that Juliette had indeed taken the same tape used by IT to seal the cleaners' suits.

Bernard was upset with Juliette for taking the tape because he believed it could provide her with insight into IT's unethical practices of killing those who attempt to leave the Silo. Although Juliette failed to make the connection and understand how something seemingly insignificant could be deadly for the cleaners, Martha looked out for her. Martha ensured that the Supply team, who assist Juliette in preparing her suit before she ventures outside, did not use IT's heat tape. Instead, they sealed Juliette's suit with a more durable tape. As a result, Juliette managed to survive in the conclusion of Silo season 1.
