Last week, we showed you a clip from this week's Marvel's Agent Carter which showcased the return of The Howling Commandos from Captain America: The First Avenger. As it turns out, Tuesday night's episode "The Iron Ceiling" also features another Marvel Cinematic Universe connection, the Black Widow training program. Long before Nathasha Romanoff (Scarlett Johansson) became the Black Widow, Russia had been training young assassins, who we get to see in this new episode. If you didn't watch last week's episode, "The Blitzkrieg Button", there will be a few spoilers below.

"The Blitzkrieg Button" revealed that Peggy's new neighbor Dottie (Bridget Regan) killed the dangerous Mr. Mink with a very familiar fighting style. Showrunners Tara Butters and Michele Fazekas confirmed in an interview with IGN that Dottie is in fact part of the Black Widow program. Tara Butters revealed that they won't actually be calling her Black Widow on the show, but fans will learn more about the program in episode 105, "The Iron Ceiling".

"She's Dottie for now. And the fact is, the great and exciting thing for us is we're showing the precursor to the Black Widow Program, as you will see in the upcoming episode, 105."

In addition, we also have a new clip from "The Iron Ceiling", where Dottie asks Peggy about what sights she should see in New York, although it's clear by the end of this scene that she has a much more sinister mission. Are you excited to learn more about the Black Widow program in "The Iron Ceiling"?
