In this Severance 2×10 review, we follow the intense developments that close out the second season. The episode picks up exactly where the last one left off: Helly is confronted by her father, Jame Eagan, in the severed floor, in a scene filled with tension. Meanwhile, Mark travels to the maternal severance cabin alongside Devon and Harmony Cobel, who now appears to have turned against Lumon. There, Mark meets his innie self, triggering a profound existential confrontation.
As the story unfolds, we discover critical truths behind the Cold Harbor project, witness Gemma’s emotional breakdown, and watch Mark face a defining choice between her and Helly. The narrative escalates with surreal corporate rituals, twisted celebrations, and the constant presence of Lumon’s control—even as the system itself begins to collapse.
The reunion with Jame Eagan
The final episode of Severance Season 2, titled Cold Harbor, brings one of the most intense moments of the entire series. In this Severance 2×10 review, we explore how the story picks up exactly where the previous episode left off, capitalizing on the two strongest cliffhangers. Helly’s reunion with her father, Jame Eagan, on the Severed floor is one of the most impactful moments. As she’s trying to memorize a note left by Irving, he suddenly appears. The tension is immediate, and Jame’s line, “You deceived me, my Helly,” finally gets a response in this episode, deepening her emotional conflict.
Mark at the cabin: an internal journey
The episode surprises by not opening with the direct confrontation between Innie Mark and Harmony Cobel, despite that being the natural expectation after the previous finale left them face to face. Instead, the series chooses to initially focus on the conflict between Mark’s two versions. Upon entering the cabin, he activates his Innie self; upon leaving, he returns to the Outie. The tension escalates when the outer Mark tries to convince the inner one to help rescue Gemma. However, Innie Mark raises a crucial question: what happens to him if Lumon ceases to exist? His very existence is tied to the company, and cooperating might mean his own extinction. This initial resistance highlights the show’s central dilemma, clearly exposing the abyss that separates both halves of the same man.
The Conversation Between the Marks: Dilemma and Frustration
Mark’s existential dilemma
The series makes an interesting choice by avoiding a direct confrontation between Mark and Harmony Cobel. Instead, it focuses on a quiet and introspective exchange between both versions of Mark. Upon entering the cabin, Mark switches to his innie; when he exits, he becomes his outie again. The conflict begins when outie Mark tries to convince innie Mark to help him rescue Gemma. However, the innie raises a crucial question: what happens to him if Lumon ceases to exist? His life depends on the company, and helping could mean his own extinction. This leads to initial resistance and underscores the series’ core dilemma.

Emotional conflict and miscommunication
The conversation between the Marks goes beyond a simple dialogue. Outie Mark makes small but significant mistakes that widen the emotional gap. When he tries to connect by mentioning the relationship with Helly, he even stumbles over her name—a mistake the innie doesn’t let slide. He reacts with frustration, claiming that the outie doesn’t truly know him and would know the name of the woman he loves if he actually cared. This moment of discomfort reveals the growing divide between both Marks, with neither truly able to connect with the other.
The Secret Behind the Cold Harbor Project
A shocking revelation from Harmony Cobel
Just as the confrontation reaches its peak, Harmony Cobel intervenes with a crucial revelation. She explains that the Cold Harbor project, which Mark had been unknowingly working on, involves creating 25 different personalities to be implanted in Gemma. Each task Mark completed on the computer represented an emotional variation. In the end, both he and Gemma were to be discarded. This bombshell adds a new layer of complexity to the conflict, making it clear that Mark’s choices come with an even higher cost than he realized. In this Severance 2×10 review, we highlight how this revelation transforms character dynamics and completely alters Mark’s perception of his role in the project.
Tension and Strange Rituals
The symbolic painting and preparation for the end
Back on the Severed floor, innie Mark notices a new painting on the wall. The image, with Mark at the center at his desk and the main innies arranged around him in a circle, symbolizes his importance on that day and Lumon’s high expectations for him. The composition resembles a Renaissance artwork but carries the artificial tone of Lumon’s world. This scene sets the stage for the episode’s climax, signaling that the severance journey is about to reach its conclusion.
A transformed Severed floor
The episode picks up pace from this point. The severance floor, once a cold and controlled space, now takes on a darker atmosphere. The lights are off, creating a sense of suspense and tension, but the monitors remain on — suggesting that control is still present, albeit in a distorted form. Mark and Helly resume communication while working, with the episode cutting quickly between moments, hinting at a longer conversation while leaving much of their dialogue between the lines. The question remains: will Mark go all the way with the plan, or will he be convinced to act before it’s too late?
In the emotional conversation between Mark and Helly at the macrodata table, Helly tries to convince him to save Gemma, go through reintegration, and try to keep living as a complete person. But a visibly moved Mark says:
— But I want to live with you.
To which Helly responds:
— But I am her, Mark. I am her.
This line carries multiple layers. On one hand, Helly seems to be affirming something profound: that she might not be separate from Helena Eagan — but rather a true and essential part of the whole person. On the other hand, her words also suggest something equally emotional: that, for the innie Mark, she is the person he has come to love and want to protect — just as the outie Mark still fights to save Gemma. The scene reveals not only the emotional conflict within Mark’s divided self, but also a possible shift in Helena’s awareness — perhaps, after the confrontation with her father, she has begun to question the boundary between who she is and who her outie is.
A dissonant corporate celebration
When the project percentage reaches 100%, expectations are shattered. Lumon’s top brass mobilizes to celebrate the project’s completion, and Milchick enters the Severed floor in a bizarrely upbeat corporate spectacle. With dancers, drums, and applause, he’s accompanied by a robot representing Kier. The scene blends humor, tension, and surrealism—like an out-of-place commercial break in the middle of a psychological thriller. It’s an awkwardly cheerful moment that disrupts the emotional gravity of the situation, highlighting the company’s distorted sense of celebration.
The Reunion with Gemma and the Final Severance
Cold Harbor: the peak of the experiment
Before Mark finds Gemma, the episode reveals that Cold Harbor is the final and most intense stage of Lumon’s experiment. In this space, the inners are exposed to their most significant trauma, carefully reconstructed through sensory triggers — such as images, sounds, and objects — but without conscious access to the associated memories.
In Gemma’s case, this room recreates the loss of her baby, making it the most critical of the 25 severances she underwent. The goal is to test how far it’s possible to separate pain from memory, creating a person capable of enduring trauma without being emotionally affected by it — a solution the company hopes to offer to the world.
Mark and Gemma’s reunion
It’s within this highly sensitive setting that Mark finally finds Gemma. Mauer, who is monitoring the scene, tries to stop any interference. He warns her that Mark is there to hurt her and tells her not to touch him.
However, Gemma disobeys — she takes Mark’s hand. This seemingly simple gesture is filled with meaning and breaks through the emotional control the experiment was meant to enforce.
As a direct consequence, Jame Eagan reacts in shock, realizing that something unexpected has occurred: Cold Harbor is compromised.
Memory returns and the experiment collapses
Shortly after leaving the room, the severance protocol is undone, and Gemma finally remembers who Mark is. Apparently, the trust Gemma showed by following Mark while still severed put the Cold Harbor experiment in jeopardy.
So, is the series suggesting that the human essence goes beyond memory?
The elevator dilemma
As Gemma remembers Mark, there is a moment of relief. They embrace and reconnect. However, as they move through the elevator, the severance takes place again. Mark transforms into his innie, and Gemma becomes Ms. Casey. The kiss they share in the elevator symbolizes a reunion that, while deeply emotional, also reflects the instability of Lumon’s system. The separation remains, and the transformation is inevitable.
The Final Choice and Separation
Mark chooses Helly
As Mark and Gemma reach the exit, the severance occurs once more, forcing Mark to make a choice. He decides to go with Helly, leaving Gemma behind. The separation is both symbolic and painful. Mark’s decision to follow Helly instead of Gemma represents a definitive break from his previous life and the beginning of a new chapter.
A symbolic season finale
The season ends with a frozen image of Mark and Helly holding hands, running down a Lumon hallway. The scene is symbolic, marking the irreversibility of Mark’s choice. Meanwhile, Gemma—now fully restored to her identity—continues to scream, but Mark no longer looks back. The series concludes with this decision, making it clear that for Mark, the severance is not only physical but emotional. His choice to stay with Helly instead of Gemma marks the end of his journey through identity and love.
What to Expect from Season 3?
The final episode of Severance brought some answers, but it also left so many questions in the air that the anticipation for season three has never been higher. The Severance 2×10 review showed us that Mark made his choice by following Helly, leaving Gemma behind — but what does that really mean for his future?
Among the questions that remain open are:
- Will Mark be able to reconcile his two versions, or will Lumon’s dilemma continue to haunt him?
- Now that the truth about the Cold Harbor project has been revealed, what will happen to Gemma’s 25 personalities?
- How will Lumon, as an institution, react to the consequences of these severances, now triggered by the inners themselves, who refused to submit to the control of the Eagan family’s company?
- In the end, Mark and Helly’s innies decide to stay on the Severance floor, but what do they plan to do now? How will they escape Lumon’s retaliation, considering they’re confined to a single floor?
With so many unresolved threads, it’s hard to predict where the show is headed, but one thing is certain: Season 3 will be full of new twists and even deeper dilemmas. In this Severance 2×10 review, we explored how the characters’ choices have set a new path for the narrative—but the biggest answers are still ahead. Fans are eager, speculating on where the plot will go next, while knowing that many answers will only come in future episodes. What lies ahead for Mark, Helly, and the others whose identities have been reshaped by Lumon? Will the show dive deeper into psychological complexity or explore new forms of control and severance?
Expectations are sky-high—and one thing’s for sure: Severance’s future will keep challenging the limits of identity and control.
