Rachel Marsh plays Claudia in Prime Video’s Fallout. This guide focuses on the performance, the character’s story, and the episodes in which the role appears, with spoilers clearly separated from the introductory material.
Who Rachel Marsh plays in Fallout
Claudia is one of the junior Vault-Tec employees preserved in Vault 31. Unlike the pre-war executives viewers meet through flashbacks, she is forced to discover the consequences of Vault-Tec’s plan in real time.
The character page for Claudia follows the story itself, while this page stays centered on Rachel Marsh and how the role is presented on screen. Keeping the two pages separate makes it easier to explore the series without forcing an actor biography and a spoiler-heavy character history into the same article.
The performance
Claudia begins as one of the thawed Vault-Tec employees, but her continued presence gives Norm someone specific to react to as the group moves from corporate conditioning into the actual wasteland. Marsh plays that uncertainty with a useful mix of fear and adaptability.
Claudia helps keep Norm’s Season 2 storyline from becoming a faceless crowd narrative. By the finale, her survival places her in a position to matter beyond the original Vault 31 reveal.
Claudia across the series
Season 1
Claudia is introduced in Season 2 when Norm wakes the frozen group and persuades them that leaving the vault is part of a management test.
Season 2
Her journey with Norm reaches Vault-Tec headquarters, where the group collapses under pressure and internal conflict. Claudia’s survival through the finale leaves her as one of the few people who has seen both the management experiment and the ruined world it was supposed to inherit.

Career beyond Fallout
Public information about Marsh is less extensive than it is for the series leads, so this profile concentrates on Claudia’s credited Season 2 storyline rather than inventing a broad biography.
This section is intentionally concise. Vault-Tec.com’s coverage is designed around the television series, so the strongest internal links point to the role, the episodes and the broader cast guide rather than stretching a series-focused page into an unrelated filmography database.
