Severance follows Mark and a team of office workers whose memories are surgically divided between work and personal life. When a mysterious colleague appears outside work, Mark begins searching for the truth about the job. Here’s who plays the principal characters, grouped by where they fit in the story. Spoilers are clearly marked.
Mark and the workplace team
Apple’s official cast listing uses short character labels for several roles. The fuller spellings noted below come from the Television Academy’s 2025 nominations list.

| Performer | Character | Place in the story |
|---|---|---|
| Adam Scott | Mark | Leads the office team at the center of the series. |
| Britt Lower | Helly | A member of the workplace ensemble. The Television Academy lists Lower’s role as Helly Riggs / Helena. |
| Zach Cherry | Dylan | A member of Mark’s office team. The Television Academy lists the character as Dylan George. |
| John Turturro | Irving | A member of the workplace ensemble. The Television Academy spells the credited name “Irving Baliff.” |
| Dichen Lachman | Ms. Casey | A character in the workplace story. |
| Christopher Walken | Burt | A character connected to the workplace ensemble. |
The Academy’s formal award-document spellings are more specific than Apple’s shorter labels; they are useful for identifying the credited roles, but do not by themselves explain the characters’ full stories.
Lumon management and staff
| Performer | Character | Place in the story |
|---|---|---|
| Patricia Arquette | Harmony Cobel | A Lumon figure whose full character name appears in Apple’s cast listing. |
| Tramell Tillman | Milchick | A Lumon figure; the Television Academy’s 2025 nominations list gives the fuller name Seth Milchick. |
| Sarah Bock | Miss Huang | Listed among the principal cast by Apple. The official listing does not add a fuller character description. |
Mark’s connections outside work
| Performer | Character | What the official synopsis establishes |
|---|---|---|
| Jen Tullock | Devon | Part of the cast around Mark’s personal-life story. |
| Michael Chernus | Ricken | Part of the cast around Mark’s personal-life story. |
Apple’s synopsis distinguishes Mark’s work life from his personal life and says a mysterious colleague appears outside work. It does not provide a complete relationship map or character chronology, so this guide keeps those connections spoiler-light.

Spoilers: fuller character credits
Spoilers are limited to character-name information. The Television Academy’s official 2025 nominations list credits Britt Lower as Helly Riggs / Helena, Tramell Tillman as Seth Milchick, Zach Cherry as Dylan George, and John Turturro as Irving Baliff. Apple’s cast page uses the shorter labels Helly, Milchick, Dylan, and Irving. These fuller credits identify names associated with the roles; they are not a substitute for a season-by-season explanation of the revelations.
