The fourth chapter in the Avengers franchise will indeed wrap the narrative that the Russo brothers started when they helmed Captain America: The Winter Soldier.

That movie dissolved S.H.I.E.L.D., put Captain America (Chris Evans) on a rebellious path to saving the soul of Bucky Barnes (Sebastian Stan), and in doing so, it paved the way for Civil War by fracturing the Avengers, leaving them all vulnerable for Thanos' invasion as he aims to reshape the galaxy.

“For us, this was the challenge of telling the story but also completing the personal journey that we started as storytellers in Winter Soldier," Joe Russo told Spin 1038 on the press circuit in London. "So the story that began in Winter Soldier and that ends in Avengers 4 is a, there’s a very personal arc there for us. I think you’ll understand our point of view as filmmakers and who we are as people when you watch all four of those movies together.”

The title of Avengers 4 has been kept secret as it may spoil the end of Infinity War, so no one knows just how the Russos' main players such as Cap, Bucky, Black Widow and the Falcon (or the entire resistance for that matter) will fare. They were seen fighting with the Wakandan contingent against Thanos' Outriders, indicating that Bucky's redemption will come full-circle with these "Secret Avengers." As for the popularity of Bucky (now known as the White Wolf), Anthony admitted that it was a surprise but one that worked out in their favor.

“Yes, that was a revelation for us, to be honest with you, because we didn’t know going into Winter Soldier. We knew why we wanted to make the movie. We knew what we loved about the character. We knew where we wanted to take it and what we wanted to do with that movie. But we didn’t know how anybody else in the world would respond. So, having the movie received like that was a validation for Joe and me that we should just stick with our instincts and our passion for the material and run with that. And hopefully, that’s what’s going to translate to audiences.”
