Following Earth's Mightiest Heroes' victory over Thanos in Avengers: Endgame, Steve Rogers/Captain America went back in time to live with Peggy Carter and, as an old man, handed over his vibranium shield to Sam Wilson/Falcon. Directors Joe and Anthony Russo and writers Christopher Markus and Stephen McFeely have offered differing opinions on whether Steve created an alternate timeline by going back to live with Peggy, with the former saying he did and the latter saying he didn't.
Marvel Studios President Kevin Feige weighed in on the debate with a rather confusing Star Wars quote.
When Empire asked Feige how a much older Rogers appeared at the end of the film, he replied, "That's a good question, for another time... Who says that? Maz Kanata in The Force Awakens in regard to, how did Luke Skywalker's lightsaber get in your castle. Ever since I heard that line I said, I'm gonna use that – a lot!"
The quotation, which is from 2015's Star Wars: The Force Awakens, comes in response to Maz Kanata being questioned about how she got Luke Skywalker's original blue lightsaber, which was seemingly lost in Cloud City during his iconic duel with Darth Vader in Star Wars: The Empire Strikes Back.
Markus recently endorsed a long-running theory both older and younger Rogers were present at Carter's Captain America: Civil War funeral. He and McFeely have also said they believe Steve is the mysterious husband of Carter and the father of her children.
