4. What Happened To Peggy Carter After Captain America?
One of the more devastating plot threads left hanging in the MCU, and a far more engaging romance than Thor and Jane, is that of Peggy Carter and Captain America in his first movie, though due to him being revived 70 years in the future at the movie's end, that of course made a future with Peggy absolutely impossible, given her accelerated age by 2012. Still, it was widely expected that The Avengers might have featured Cap visiting an elderly Peggy, and though Hayley Atwell at first refused to confirm that she would be returning for The Winter Soldier, she has since been spotted on set in old lady makeup, so hopefully the movie will give her character a tender reunion with Cap, which could make for one of the most emotionally resonant moments in the entire MCU. The upcoming Marvel One-Shot: Agent Carter should shed some light on her post-Cap activities, though it will be The Winter Soldier that should provide some closure to her story.
