'Marvel's Agent Carter' Spoilers: Will Hayley Atwell's Peggy Carter Discover Black Widow's Origin? [WATCH]

The countdown has begun as Marvel's Agent Carter has only 3 episodes left on ABC. As the manhunt for Howard Stark (Dominic Cooper) escalates, will Peggy Carter (Hayley Atwell) discover how the Black Widow Program came about and spawned the deadly assassin, Natasha Romanoff (Scarlett Johansson)?

In our first recap, Peggy (Atwell) was seen as a hero as she fought bravely in World War II, but her co-workers at the Strategic Scientific Reserve think she's a complete joke. Framed for crimes he didn't commit, Howard Stark (Dominic Cooper) needs Peggy to clear his name after his inventions, which he calls "bad babies," have been stolen.

In our recent recap, Stark came back to the states after being on the run. Unfortunately, the mission changed for Peggy when she discovered she was actually stealing a vial of Steve Rogers (Chris Evans)' blood. With their friendship in ruins, Stark needs his butler Edwin Jarvis (James D'Arcy) to get her back.

The episode also revealed Dottie (Bridget Regan)'s true identity. While pretending to be Peggy's roommate, Dottie ambushed Mr. Mink and snapped his neck. If you noticed how Dottie fought, she used the exact same moves we saw from Romanoff (Johansson) in Iron Man 2.

According to Screenrant, The Iron Ceiling not only features a reunion from the Howling Commandoes, including Dum-Dum Dugan (Neal McDonough), but also takes viewers inside the Black Widow Training grounds.

The official synopsis states, "Peggy is finally trusted with a mission and calls upon her trusted Howling Commandos squad for backup. But her cover could be at risk when SSR Chief Dooley also sends Agent Thompson with her."

Check out this clip from tonight's The Iron Ceiling here:

If you notice in the footage, we see Dum-Dum and Peggy chasing after a little girl, who has just stabbed someone. Could that little girl possibly be Romanaoff?

We have 5 reasons why you should be watching Agent Carter.

Marvel's Agent Carter continues Tuesdays at 9pm on ABC.
