As you're now no doubt well aware,
Avengers: Endgame ends with Steve Rogers travelling back in time to finally live out his life alongside Peggy Carter. On the surface, him growing old in the Marvel Cinematic Universe until he's able to pass on the shield to The Falcon is a pretty perfect ending, but this world's rules of time-travel definitely confuse matters.
Travelling back in time would have created a new reality, so in order to meet up with Sam, Steve would have had to use those Pym Particles to return to the original timeline where nothing would have changed. Since day one,
Avengers: Endgame's writers have been singing from a different hymn sheet to Joe and Anthony Russo, and they've once again muddied the waters.
"It was always our intention that he was the father of those two children," Stephen McFeely reveals, explaining that Steve Rogers was always meant to be the man in those photos by Peggy Carter's bedside in
Captain America: The Winter Soldier.
"But again, there are time travel loopholes for that."
"It does introduce the idea that there are two children who have somewhat super soldier DNA," Markus added, hinting that there's still more to this story than meets the eye.
At this stage, it's hard to escape the feeling we're being worked and Marvel Studios is planning on explaining what Steve Rogers was up to for all those years (thereby providing an official explanation of what impact his return to the past had on the timeline in the process). Whether that comes in the form of a movie or a Disney+ TV show remains to be seen.
