The Marvel Cinematic Universe Phase 4 is starting another Civil War with Captain America: Civil War. The Phase 3 film introduced the Sokovia Accords and split the Avengers apart, only for them to regroup a few years later.
Sam and Bucky are no longer fugitives when The Falcon and The Winter Soldier begins but their actions might be leading to another superhero rift. Captain America's former sidekicks teamed up again in episode 2 and quickly found themselves fighting with Steve's replacement. John Walker's Captain America and his sidekick Battlestar help Sam and Bucky at first, but it doesn't take long for Falcon and Winter Soldier to reject their help. By continuing to push Captain America and Battlestar away, The Falcon and The Winter Soldier is setting up a battle between two different types of heroes.
The end of The Falcon and The Winter Soldier episode 2 saw Walker help get Bucky out of an arrest and try once more to convince Bucky and Sam to team up with him. However, they reject his offer, with Sam noting that they are "free agents" in the superhero game who don't answer to anyone. This doesn't sit well with Walker who then threatens them to stay out of his way. The obvious friction between Sam and Bucky and Captain America and Battlestar appears to set up The Falcon and The Winter Soldier making Civil War 2 about regulated vs unregulated heroes.
Regulated heroes vs unregulated heroes can be how Phase 4 tackles the same idea of Captain America: Civil War but in a slightly new way. The Phase 3 movie focused on the difference between heroes who ed with the Sokovia Accords and those who didn't. This created a great divide in the Avengers, but there wasn't much exploration of the consequences of these decisions. With Sam and Bucky now seemingly following in Steve's footsteps to avoid oversight by anyone with their own agenda, The Falcon and The Winter Soldier can revisit this topic if its lead characters' actions are not sanctioned by the government. This could even lead to Sam and Bucky no longer being able to get help from Joaquín Torres and the Air Force.
If The Falcon and The Winter Soldier is the start of a Captain Marvel 2, being a loose Civil War II adaptation.
