MCU Theory: Captain America Watched the Avengers from the Sidelines as Agent Carter’s Secret Husband the Whole Time

In Avengers: Endgame Steve Rogers, aka Captain America travels to the past to return the Infinity Stones to their original timelines. But he ends up staying in there to reconnect with his true love Peggy Carter

He then returns to the team as an old man, suggesting he lived out a full life. Some fans believe Steve was Peggy’s secret husband, and that he was watching the Avengers and another version of himself from the sidelines the whole time.

Agent Peggy Carter’s husband was never seen

In Captain America: The Winter Soldier, Agent Peggy Carter (Hayley Atwell) reveals that she has a husband who Captain America saved during World War II. And she also confirms that she has two children with him. 

Peggy’s husband is never seen on-screen, and she never tells Steve his name. As far as the Marvel Cinematic Universe is concerned, the identity of Peggy’s husband still remains unconfirmed. 

Was Captain America Peggy’s husband this whole time?

Steve returned to the Avengers timeline at the end of Avengers: Endgame, which suggests he’s been living with Peggy in that timeline for years. As one MCU fan theorized on twitter, Steve was “always in the prime timeline,” living out his days with Peggy.

“Steve Rogers has always been Peggy’s mysterious husband that was ‘saved by Captain America in the war,’ and has been watching the MCU from the sidelines,” the fan wrote in a series of tweets. “It can be surmised that when Steve decided to travel to 1948 after returning the stones, and for him to appear on the bench at the end, the branch timeline Steve created by returning to Peggy *IS* the Prime Timeline!”

“All the events of the MCU, from Iron Man to Endgame, have been in the timeline Steve created by staying with Peggy,” the fan continued. “It’s corny but, it was always destined to happen. He comes up with some BS that he was a soldier Cap saved to keep his identity secret, and boom.”

The ‘Avengers: Endgame’ screenwriters confirmed it

This primary timeline theory was thwarted by directors Joe and Anthony Russo, who suggested Steve created a branch reality when he traveled back. But Avengers: Endgame screenwriters, Stephen McFeely and Christopher Markus, confirmed it was actually true. They wrote the story with Steve as Peggy’s secret husband this whole time. 

“It was always our intention that he was the father of those two children,”  co-writer Stephen McFeely told the Hollywood Reporter. “It does introduce the idea that there are two children who have somewhat super soldier DNA.”  

In another interview with Canada.com, the screenwriters went into more detail. And they suggested that while they feel Steve’s been a part of this primary timeline, Marvel may not be on board with the idea.

“Chris and I are partial to the idea that Steve is part of a strange, unique time-loop where he has always been there,” said McFeely. “The husband that you very purposefully did not see at Peggy’s bedside in Winter Soldier is Chris’ Steve. We have always thought that he was her husband. The movies you have been watching follow a line where he always goes back. To be fair, not everyone agrees with us. I don’t even know if Marvel agrees with us. But that’s what we think.”
