In original continuity, Sharon was said to be the younger sister of Captain America's wartime love interest, Peggy Carter, but due to the unaging nature of comic book characters, she was later retconned as Peggy's niece. She grew up with the stories of her aunt, Margaret "Peggy" Carter, who was a freedom fighter with the French Resistance during World War II. During this time, Peggy worked alongside Steve Rogers, the patriotic hero known as Captain America, on several occasions. The two fell in love despite Rogers never finding out her name, but were separated in the closing weeks of the war. They did not find each other again before Rogers was thought dead, lost in the freezing waters of the North Atlantic.
"Captain America" adaptation, adding to the four we learned about last week (read about that here).
