A new Avengers 4 fan theory seems to have a good line on how Captain America’s story could come to a close.
We won’t know until next year how Captain America will make his exit from the MCU, but this fan theory from Digital Spy is fun to think about while we wait for Avengers 4 to hit theaters.
With all of that being said, the new Avengers 4 theory predicts that we will see the surviving members of the Avengers travel back in time to certain events from past MCU movies, which leads us to Bucky Barnes as well as Peggy Carter from the first Captain America film.
If Atwell returns, this could be how Captain America ends his run in the MCU.
