So obviously Peggy got married and had children, but if you’ll notice in Winter Soldier, we only see pictures of her and her kids next to her bed. There is no picture of her husband. For some reason, this sparked an idea. I came up with a headcanon/story for this at like 3 am one night when I couldn’t sleep. (Sorry, this will probably be long.)
Peggy and Angie get together at some point and fall madly in love, but Angie finally gets her big break on Broadway and Peggy is very busy with work. So they start to drift apart, and eventually (even though they don’t want to), they break up. Sousa is still crushing on Peggy, so he pressures her to go on a date with him. She reluctantly agrees, but they have a good time, and they eventually get married. They have three children. Peggy starts to resent Sousa because she feels like he pushed her into married life and away from her job. They have all sorts of problems, and their marriage is going down the drain. Then Peggy runs into Angie for the first time in years. Instantly, all their feelings for each other come rushing back, and they decide to go out for coffee. They talk for hours to catch up, and Peggy tells her she’s not happy in her marriage. Angie urges her to leave because she hates to see her so miserable. Peggy decides that Angie is right and divorces Sousa. Peggy and Angie finally get together again, but Peggy’s children resent Angie because they think she tore their parents’ marriage apart. They are also mad at Peggy because not only are they bitter about the divorce, but they are not supportive of same-sex relationships. When they are old enough to move out, they tell Peggy they don’t want to see her or talk to her again. Peggy tries to keep tabs on them as much as possible and make sure they are okay, but she gives them her space. She can’t give up on Angie. She’s already lost Steve. She won’t lose Angie, too. So they spend the rest of their lives together. Angie passes away a few years before we see Peggy again in Winter Soldier. Obviously, Peggy gets Alzheimer’s. Her children come back and decide to put her in a home. She wants to bring pictures of the kids and pictures of Angie to put by her bed. The kids refuse to put pictures of Angie in her room, but put the others in there. On her deathbed, she apologizes to her children for not being a better mother. They tell her not to apologize. THEY are sorry for for not respecting her relationship with Angie. And then one of her children pulls out a picture of Angie and places it next to Peggy’s bed. Peggy then passes away peacefully that night.
