In Silo season 3, who is Robert Sims' wife?

In Silo season 3, Robert Sims’ wife is Camille Sims.

Camille is Robert’s spouse and the mother of their son. She is played by Alexandria Riley, while Common portrays Robert Sims, the senior Judicial official whose career places him close to the Silo’s most powerful institutions.

Camille was not part of the original plan for the series. Graham Yost explained that the character emerged when the writers needed a place for Juliette to hide and began developing Sims’ home life. That decision expanded Robert from a political enforcer into a husband and father with competing loyalties.

A common mix-up is confusing Camille with other Silo spouses, such as Kathleen Billings or Carla McLain. Camille is especially important because her relationship with Robert becomes tied to the Silo’s succession and security decisions.
