Shell

Zoe Shannon meets a gruesome death in the treatment pod. After Chloe smashes through her glass cage and kills Randolph Chan, Brand, and Zoe's bodyguard, Zoe panics and locks herself inside the treatment machine. The pod's heat and pressure activate automatically, frying her instantly and leaving only a bag of charred tissue. This ironic death occurs because Zoe, who pushed the dangerous youth procedure on others, ultimately becomes a victim of her own technology.

Chloe's ultimate fate remains ambiguous. After breaking out of her glass cage and killing Randolph, Brand, and the guard, she encounters Samantha on the floor. The monstrous creature pauses briefly at Samantha's feet, suggesting a fragment of her former humanity remains, before fleeing the clinic. The film does not show what happens to Chloe afterward, leaving her survival and whereabouts unknown.

Chloe spares Samantha likely because of their personal connection. Samantha was Chloe's former babysitter, and despite the horrific transformation caused by Shell's treatment, some fragment of Chloe's humanity appears to remain. When the creature pauses over Samantha and does not attack, it suggests that deep memories of their relationship persisted even after the physical metamorphosis, allowing Samantha to survive while everyone else in the room was killed.

Earlier references to Samantha having babysat Chloe establish their emotional connection.

The film implies Shell continues operating despite the exposure. In the final scene, Samantha publishes her memoir and exposes the company's dark practices, but the closing moments suggest the corporation remains powerful, likely with tighter NDAs and more covert control. The epilogue hints that Samantha herself may still be tempted by the very treatment she once denounced, suggesting Shell's influence persists beyond the scandal.

Samantha rejects Shell's offer because she refuses to become a complicit silent partner in their crimes. When Randolph Chan and Dr. Brand offer her lifetime free treatment and a share of the company in exchange for her silence, Samantha sees it as an attempt to make her a mute spokesperson for an operation that turned people into monsters. Her rejection represents a moral stand against participating in the exploitation that nearly killed her and transformed Chloe.

The detectives reference Shell's "protection" program when they warn Samantha that her NDA could land her in legal trouble if she speaks out. They suggest she comply with Shell's program rather than cooperate with law enforcement. This appears to be a euphemistic term for the company's coercive system of keeping victims silent through legal threats and potentially offering limited treatment in exchange for their cooperation, essentially a control mechanism to prevent whistleblowing.

Dr. Hubert reveals he knew Chloe Benson personally, they fell in love while trying to help her after her transformation began. As Shell's employee, Hubert attempted to reverse the dangerous side effects of the youth-preserving injection, but his efforts only turned Chloe into the monstrous creature Samantha later discovers. Their relationship adds emotional stakes to the plot and explains why Hubert risks everything to help Samantha escape.

The transformation is a severe side effect of Shell's "youth-preserving" injection. After receiving the treatment at Zoe Shannon's clinic, clients begin sprouting black, oozing lesions that spread across their skin. In extreme cases like Chloe's and eventually Samantha's, the reaction escalates into full metamorphosis, turning victims into gigantic, shell-covered creatures. Dr. Brand casually dismisses these outcomes risks for a as acceptable procedure that promises eternal youth, revealing the company's ruthless priorities.

After escaping the clinic, Samantha publishes a memoir that chronicles her entire ordeal and exposes Shell's dark practices. This act of whistleblowing brings her professional success and closure, but the ending remains bittersweet, while she survives and achieves a form of justice, the corporation's continued existence and her own lingering temptation by the treatment suggest her battle is not fully over.

When Chloe smashes through her glass cage, she kills three people: Shell's lawyer Randolph Chan, the company's founder Dr. Thaddeus Brand, and Zoe's personal bodyguard. Only Zoe and Samantha survive the initial attack, Zoe by locking herself in the treatment pod (where she then dies), and Samantha because Chloe spares her. This violent climax represents the collapse of Shell's leadership.
