Another theme is the anticipation of the future. The fanfic might explore how Scully envisions raising the child, what kind of world she wants to create for it, and how her past experiences influence her hopes for the future.
There could also be themes related to the mystery of her pregnancy. Given the sci - fi nature of The X - Files, some fanfics might explore if there are any unusual or otherworldly elements to her pregnancy. Maybe her baby has some special powers or there are forces trying to target her unborn child.
Another theme could be the relationship with Mulder during her pregnancy. It might explore how Mulder supports her, or how their dynamic changes as they are about to become parents in the fanfiction world. Also, there could be themes related to the mystery or danger from the X - Files universe affecting her pregnancy, like some sort of alien or conspiracy - related threat.
One common theme is the development of their relationship. With Scully being pregnant, it often deepens their bond, like Mulder becoming more protective. Another theme is the fear and anticipation. Scully might be worried about the health of the baby due to her past medical history, and Mulder shares in those concerns. Also, there's the theme of how their work on the X - Files is impacted. Maybe they have to take a break from investigations, or they find new mysteries related to Scully's pregnancy itself.
One common theme is the exploration of their relationship. Whether it's deepening their romantic connection or strengthening their friendship as partners. Another theme is solving mysteries, just like in the show.
The theme of Scully's relationship with her family also comes up. Her mother's reaction, or how her pregnancy might change her family dynamics. Some fanfictions might also explore how Scully's pregnancy affects her relationship with other colleagues at the FBI. It could be that they are more protective of her, or there could be some jealousy or resentment from other female agents who see her getting special treatment because of her pregnancy.
One common theme is trust. In many of these fanfics, Mulder and Scully have to trust each other in different situations, especially with Mulder being in a more dominant role. Another theme is the exploration of their unspoken feelings. Since they have a complex relationship, fanfic writers often dig into those hidden emotions.
The theme of isolation also comes up. Sometimes Scully is hurt in a way that makes her feel alone, either because she doesn't want to burden Mulder or because the nature of her injury separates her from the normal world. This can lead to some really emotional and introspective moments in the fanfiction.
Themes like mutual understanding are quite common. Skinner and Scully understand each other on a level that others in the X - Files universe don't. They can communicate without words sometimes. Additionally, there is the theme of protection. Skinner might protect Scully from the more bureaucratic elements of the FBI, while Scully might protect Skinner from the unknown threats that come with the X - Files cases.
One possible theme is the idea of new beginnings. Their relationship has been through so much, and now a baby represents a fresh start. Another theme could be protection. Mulder will surely want to protect Scully and the baby from any harm. And there might also be a theme of family, as they are now about to become a family unit, which is a big change for them.
One interesting plot could be Scully dealing with the challenges of her pregnancy while still being involved in her work. Maybe she has to hide it from some colleagues at first. Another could be how the father of the baby (depending on who it is in the fanfic) reacts and supports her. It could also explore how Scully's pregnancy affects her relationships with her friends and family in the fanfic universe.
