New reference postulates that the Avenger will appear as an ally of the protagonist, given that the events occur before Avengers: Endgame.
Black Widow is one of the most anticipated movies for MCU fans. Not only will it mark the beginning of Phase 4 of the cinematic universe, but it will also convey Scarlett Johansson’s farewell from the franchise.
The story is set before the events of Avengers Endgame. In this film, Steve Rogers retires as Captain America to have a quiet life until he grows old, but that does not prevent him from reappearing as an ally of the protagonist
According to ScreenRant, Captain America will appear in the movie and not just referenced. The character is directly involved in the narrative if they tell the story of how Natasha Romanoff joins him in hiding as we saw in Captain America: Civil War.
Specifically, the scene will not show how she contacts the avenger to join his cause. Also, the superhero would make a small cameo to meet the Russian spy. Without a doubt, a storyline connection that fans would appreciate seeing in the movie.
