When Peggy Carter heads out west, she won’t be alone.

EW has learned exclusively that James D’Arcy and Enver Gjokaj—who play Edwin Jarvis and Agent Daniel Sousa, respectively—have signed on as series regulars for season 2.

While Marvel declined to comment, we hear deals for Chad Michael Murray (Agent Jack Thompson), Bridget Regan (Dottie Underwood) and Lyndsy Fonseca (Angie Martinelli) are forthcoming. Hayley Atwell, naturally, is already slated to return.

Here’s the description of the new season: “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.”

Agent Carter is slated to return midseason on ABC.
