In short, she chose Sousa!
file that seems to implicate Peggy in a massacre.
Whats really going on?
EW turned to Atwell to get the scoop.
(Read our full postmortem with executive producers Tara Butters and Michele Fazekashere.)
ENTERTAINMENT WEEKLY: How do you feel about Peggy and Sousa finally making a go of it?
HAYLEY ATWELL:Im so happy!
In the workplace, her gender is considered a disability.
Sousa has a disability from the war, and therefore has to deal with that limitation.
I think its inevitable that they end up together.
Hes not intimidated by her.
I think thats a bloody hard thing for men in the 1940s to not be intimidated by.
Hes pretty special in that regard.
Do you think Sousa could bethe husbandthat Peggy was talking about inCaptain America: Winter Soldier?
I dont know, because she says that Captain America saved her husband.
Thats a possibility, too.
I like to think that this is the start to a beautiful relationship.
How do you think Peggy will handle Thompsons potential death, especially since its happened because of that file?
She has an interesting relationship with Thompson.
I think she deals with him with a bemused tolerance.
Shes not a dismissive person.
Shes quite tolerant of people.
Shes quite patient and wants to appeal to the good in him.
Planting that seed in him is her hope that he will continue to be a good man.
So to lose him, I think she would grieve, but its not the same.
I dont think she would regard him as a friend.
Hes not someone that can be trusted.
She suspects that hes capable of making really bad decisions, but not malicious ones.
How much do you actually know about this file that discusses Peggys exploits with the S.O.E.
Peggy seemed to dismiss it before, but do you know whats really going on there?
James DArcy is so nosy, so he went sniffing around the writers room trying to figure it out.
I do know what that secret is.
Its really exciting, and it changes a lot.
It basically gives us our core for season 3 if we were to go to a season 3.
Or it might get picked up in a couple years.
Im sworn to secrecy on it, but its really clever.
When you found out what it was, did it change the character in your mind?
It changes what Peggys about to experience.
Things are not what they seem.
Its really terrifying and scary.
It will change her view of the world.
Expect news on whetherMarvels Agent Carterwill return sometime in May.
