Sharon Carter, as played by Emily VanCamp, didn’t really have much to do in Captain America: The Winter Soldier. She’s ostensibly the love interest in the film, but she’s not the woman that Cap actually kisses in the movie (that would be Black Widow). The movie ends and Captain America still doesn’t know that she’s the niece of Peggy Carter. Luckily, despite the massive roster of superheroes in Captain America: Civil War, Sharon has much more to do. Despite her distinct lack of superpowers, she heads into battle, and even shares a moment of romance with Steve, which may disappoint Stucky fans who have imagined a world where Steve and Bucky are the ones in love.
Ms. VanCamp had never heard of the world of internet slash fiction and the fictional gay adventures of Captain America and The Winter Soldier, so we introduced her to that world and talked about the future of Sharon Carter in the Marvel Cinematic Universe. Minor spoilers for Captain America: Civil War ahead.
