One common theme is loyalty. Natasha is often depicted as being torn between her loyalty to different sides during the Civil War. Another theme is sacrifice. She may have to sacrifice personal relationships or her own safety for the greater good. And there's also the theme of redemption, as she tries to make up for past actions in the context of the Civil War.
The theme of sacrifice also often appears. Given that they are in the middle of a war, there are times when they have to make difficult choices. They might sacrifice their own safety or even their own identities to achieve a greater goal for the war effort. Their 'ghost - like' existence sometimes means they are willing to disappear completely if it means victory.
In many fanfictions, Natasha's redemption in the context of Civil War often involves her trying to make amends for her actions that led to the divide among the Avengers. She might start by secretly working to bring both sides together, using her skills as a spy. For example, she could be gathering information on both Captain America and Iron Man's plans and trying to find common ground.
Conflict of ideals is also a major theme. Natasha and Tony have different views on things like superhero registration. In fanfictions, this often leads to intense arguments and moments of self - reflection as they both try to justify their stances and understand the other's point of view.
There's also a story where they are like phantoms in the war, titled 'Ghostly Allies'. In this fic, their skills are enhanced to an almost supernatural level, making them seem like ghosts as they move through the battlefields, taking out enemies one by one. They rely on each other's instincts and develop a deep connection that goes beyond the normal comradeship.
The relationship can develop through their shared anticipation of the baby. Steve can become more in tune with Natasha's emotions, and they can have deeper conversations about their future as a family. For example, they might talk about how they'll raise the child, whether they want a traditional or more unconventional upbringing.
