Sarita Choudhury plays Lee Moldaver / Kate Williams 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 Sarita Choudhury plays in Fallout
Moldaver is introduced as the leader of the raiders who attack Vault 33, but that first impression is deliberately incomplete. The pre-war Kate Williams was a scientist opposed to Vault-Tec’s acquisition of cold-fusion research.
The character page for Lee Moldaver / Kate Williams follows the story itself, while this page stays centered on Sarita Choudhury 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
Moldaver is first presented through other people’s fear and suspicion, then recontextualized as the story reveals Kate Williams and her opposition to Vault-Tec. Choudhury plays those layers without losing the character’s severity.
Moldaver is one of the show’s most important perspective shifts. Learning who she was changes the moral framing of several events that initially looked much simpler.
Lee Moldaver / Kate Williams across the series
Season 1
Season 1 reframes Moldaver as an NCR-aligned leader attempting to restore power to the region. Her confrontation with Hank and the revelation of Rose’s fate force Lucy to reconsider nearly everything she believed about the raid and her father.
Season 2
Although Moldaver dies at the end of Season 1, Season 2 flashbacks continue her story as Kate Williams and show how early her conflict with Vault-Tec, Cooper and the cold-fusion technology began.

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.
