The latest episode of Severance, titled “Sweet Vitriol,” has left fans reeling with questions about the mysterious Nine Principles of Lumon and the unexpected betrayal by Sissy Cobel.
This episode delves deep into Harmony Cobel’s past, revealing her connection to Lumon and the enigmatic world of ether. Let’s dive into the key elements that have captured viewers’ attention.
What Is Ether and Its Role in Severance?
In Severance, ether refers to diethyl ether, a chemical compound historically used as an anesthetic. It has both euphoric and dissociative effects, which resonate with the themes of escapism and addiction in the show.
Harmony Cobel’s past reveals her involvement in an ether factory at a young age, highlighting Lumon’s exploitation of child labor. Ether can be seen as an early form of severance, dissociating individuals from reality, much like the severance program itself.

Who Is Sissy Cobel and Why Did She Betray Harmony?
Sissy Cobel is introduced as Harmony’s aunt, though some interpretations suggest she might be Harmony’s grandmother due to her age and the way she interacts with Harmony’s mother, Charlotte.
Sissy is deeply embedded in Lumon’s ideology and is revealed to be a pariah in the town of Salt’s Neck.
Her betrayal of Harmony stems from her allegiance to Lumon’s principles, particularly The Nine. Sissy’s actions suggest she believes she is protecting Harmony by turning her over to Lumon, possibly to erase her family’s ties to Lumon’s past.
What Does The Nine Mean in Lumon’s Philosophy?
In the world of Severance, The Nine are central to Lumon Industries’ philosophy, serving as guiding principles for employees and followers of Kier Eagan.
These principles are designed to unite and inspire, fostering a sense of community and industriousness among those who adhere to them.
The Nine Core Principles of Lumon are:
- Vision
- Verve
- Wit
- Cheer
- Humility
- Benevolence
- Nimbleness
- Probity
- Wiles.
These principles are comparable to the Seven Virtues of Catholic theology, with Humility being a shared virtue. They are emphasized in documents like the Compliance Handbook and are intended to intertwine and overlap, guiding employees to become better individuals and workers.

What is The Role of The Nine Principles in Lumon’s Culture?
The Nine Core Principles play a significant role in shaping Lumon’s culture. They are displayed prominently throughout the company, including in the Perpetuity Wing, a museum dedicated to the Eagan family and Lumon’s mission.
Harmony Cobel, a devoted follower of Kier Eagan, often references these principles in her actions and decisions, demonstrating their influence on her life.

Impact on Employees
These principles are meant to create a sense of belonging and purpose among employees, encouraging them to view their work as central to their lives.
By embracing The Nine, employees are expected to embody the values of Lumon, fostering a community that prioritizes work over personal life.
Connection to Kier Eagan’s Philosophy Explained
Kier Eagan’s philosophy, which includes The Nine Core Principles, emphasizes the importance of work in an employee’s life. Alongside The Nine, Eagan’s philosophy also includes the Four Tempers (Woe, Frolic, Dread, and Malice), which are believed to define an individual’s character.
This comprehensive approach to employee development aims to create an industrious workforce loyal to Lumon’s mission.
In summary, The Nine Core Principles are foundational to Lumon’s philosophy, serving as a moral compass for employees and reinforcing the company’s unique culture and values.
What’s Next for Harmony Cobel?
After her betrayal by Sissy and her realization of Lumon’s true nature, Harmony Cobel is on a path to confront her past and possibly take down Lumon. She agrees to meet Mark, indicating her willingness to help dismantle the company she once served loyally.
This shift marks a significant turning point for Harmony as she transitions from being a devoted employee to a potential adversary of Lumon. With her newfound understanding of Lumon’s exploitation, Harmony’s future actions will likely be pivotal in the unfolding narrative of Severance.
As the series progresses, fans are eagerly awaiting more revelations about Lumon’s origins, the significance of ether, and the role of The Nine in controlling the lives of those involved with the company.
The betrayal by Sissy Cobel and Harmony’s evolving stance against Lumon set the stage for a thrilling conclusion to Season 2.
