Captain America: Civil War revealed many dark secrets surrounding some of the film's prominent characters. While the biggest reveal was that the Winter Soldier (Sebastian Stan) killed Tony Stark's (Robert Downey Jr.) parents, there were many other revelations littered throughout the film. For instance, Peggy Carter's (Hayley Atwell) death showcased its own reveals in both the theatrical cut and its deleted scenes.

During Peggy's funeral, Sharon Carter (Emily VanCamp) revealed she was the niece of Steve Rogers' (Chris Evans) old flame, but this wasn't the only family secret that the hero was made aware of. As he spent time in the church by himself, processing Peggy's death, Natasha Romanoff (Scarlett Johansson) walked in to make sure her friend wasn't alone. While the theatrical cut was a brief conversation that tied into who had and hadn't signed the Sokovia Accords, a deleted scene contained a major piece of the Black Widow's past.

In the scene, Steve talked about how he was surprised that Peggy was still alive after he came out of the ice. Natasha reminded him of how important it was to Peggy as well that the two were able to reconnect while there was still time. Nat also explained how her decision to disappear and find a new identity following the events of Captain America: The Winter Soldier tied into how Steve was feeling.

After S.H.I.E.L.D.'s collapse, Natasha decided to go and discover more about her family. The deleted scene, "Extended Peggy's Funeral," delved more into the truth regarding her parents' fate. As she explained, Nat's search led her to two gravestones by a chain-link fence. In a form of closure, Nat pulled some weeds and left flowers at the gravesite. She concluded her story by reminding Steve that "we have what we have when we have it."

Nat's character was built on loss and perseverance. She lost one family in The Winter Soldier when S.H.I.E.L.D. was dismantled, but she leaned on the Avengers as another home that she could stake a claim to. She reminded Steve that the important thing was the time he had with the people he loved, which Nat never got with her parents. With the Sokovia Accords, her family was threatened again and inevitably split down the middle. Ultimately, her death in Avengers: Endgame was something that helped bring them back together.

Captain America: Civil War showed that the Black Widow's true allegiances lay with her family. Her decision to switch sides in the third act served as a great example of that. However, the deleted scene where she discussed her deceased parents helped add another layer to her focus on family while also foreshadowing her flip later in the film. Unfortunately, the Marvel Cinematic Universe's deleted scenes aren't considered canon, so it is unclear if this information will carry over into the main continuity.
