When "Agent Carter" returns to ABC for its second season, the show will undergo some pretty major changes as Peggy (Hayley Atwell) heads out west from New York City to get a new start in Los Angeles. One thing that won't change, however, is Peggy's supporting cast.

Entertainment Weekly reports that the roles of Peggy's begrudging sidekick, Edwin Jarvis, and her coworker, Daniel Sousa, will be reprised by James D'Arcy and Enver Gjokaj respectively. Both D'Arcy and Gjokaj have signed on a series regulars. However, no word on the context or circumstances that will allow for them both to appear on the show.

Though Marvel declined to comment, reports claim that Chad Michael Murray (Agent Jack Thompson), Bridget Regan (Dottie Underwood) and Lyndsy Fonseca (Angie Martinelli) will also return for season two.

According to the second season's official description,

Dedicated to the fight against new atomic age threats in the wake of World War II, Peggy must now journey from New York City to Los Angeles for her most dangerous assignment yet. But even as she discovers new friends, a new home - and perhaps even a new love - she's about to find out that the bright lights of the post-war Hollywood mask a more sinister threat to everyone she is sworn to protect.

Starring Hayley Atwell, "Agent Carter" is scheduled to return to ABC at an as-of-yet undetermined date this fall.
