If you’re still scratching your head over whether the Old Steve Rogers that Sam encounters at the end of Avengers: Endgame is from an alternate timeline or not then thankfully both directors from the film stepped forward and gave a definitive answer in an interview with Fox 5 DC.
Throughout this, I’ll be breaking down the original confusion and discussing how Steve came to be at the end of the movie.
This is full spoilers ahead so if you’re someone who was snapped out of existence at the end of Infinity War and haven’t had a chance to watch Endgame yet then I highly recommend that you turn off now.
With that out the way, I just wanna give a huge thank you for clicking this video, I hope you enjoy it, now sit back, relax and let’s get into the full breakdown of the theory.
Old Steve Rogers Theory
Avengers: Endgame ends with Steve Rogers traveling back in time to return the infinity stones and Moljnir to their rightful places but rather than returning to the present, Steve goes back to live out the life that he should’ve had with Peggy Carter.
After going through time the old fashioned way, Steve finally sits on the bench, seemingly moments after he traveled back so that he can present his Shield to Sam and announce that he is the new Captain America.
Most of the main confusion came over whether this was actually the original Steve Rogers or if it was one from another reality. Going by the rules of the film, Cap should’ve gone back in time and created a new, alternative reality, however, the writers of the movie came forward and said that Steve was actually Peggy’s husband the entire time.
So which one is it, well the following interview with the Russo brothers finally clears it all up.
From this we can take that Captain America did, in fact, create a branched reality and at some point, he traveled back to prime reality in order to return the Shield using a Pym Particle. So, the Cap that we see at the end is from the original timeline and the one that we have followed since the past decade or so, however, the timeline that he lived in is not the same that we have been watching and Peggy did indeed have a different husband to Steve Rogers in the main reality.
It’s sort of a bittersweet explanation as I’m kind of the mindset that Peggy and Steve were always together which is why we never really heard much about her husband, however it does also mean that he never kissed his Neice which yeah….I’m glad that’s not the case either.
