'Agent Carter' returns for Season 2 and fans can expect to see a villain's major comeback. Dottie will be returning to ruin Peggy's life and the SSR. Other than that, Peggy finally moves on and finds a newfound romance. However, things will not be easy for Peggy now that Dottie is around.

As reported by Design & Trend, Dottie Underwood (Bridget Regan) will be returning in the show to cause more trouble in Peggy Carter's life (Hayley Atwell) and the Strategic Science Reserve (SSR).

Furthermore Atwell shared details that the Season 1 villain will be returning. Atwel stated that "Peggy has male baddies that she fights, but to have someone who is physically her equal-- Dottie is a Black Widow, incredibly capable and smart-- I think that shows some balance for Peggy, like a flip side of the same coin." The actress added that Dottie will have more appearances in 'Agent Carter' Season 2.

According to Franchise Herald, Dottie is a part of the Red Room Academy, which makes her a trained Soviet Assassin. She is also an alumnus of the Black Widow Program.

On the other hand Peggy will not only be facing with villains like Dottie in Season 2, she will also be facing some challenges when it comes to her newfound love. Especially now that she's done mourning over Steve Rogers (Chris Evans) as mentioned on Realty Today.

Just in time when Peggy Carter moves on over the death of Steve Rogers, Dottie Underwood enters the scene once again. This time, the 'Agent Carter' villain will make Peggy and the SSR lives difficult than ever.

The TV series' production has finally begun for the upcoming season. 'Agent Carter' Season 2 is set to premiere anytime soon on ABC this coming December. Hayley Atwell's character is set to return in the show on January 2016.
