Another angle for the fanfiction could be the reactions of their colleagues. Tony might be a bit jealous at first that Gibbs and Ziva have this special connection. Abby would be over the moon and start knitting baby clothes right away. And Ducky could offer his medical expertise and also some fatherly advice to Gibbs, who never really expected to be in this situation.
In this fanfiction, perhaps there could be a storyline where their pregnancy is a secret at first within the NCIS team. Gibbs and Ziva try to keep their normal routine while dealing with the physical and emotional changes that come with pregnancy. There could be some comical moments, like when Ziva has cravings during a case and Gibbs has to quickly find what she wants.
In some NCIS fanfiction, Ziva could be pregnant. Fanfiction often explores different scenarios for beloved characters. Writers might create a story where Ziva's pregnancy brings new challenges and developments to her relationship with Tony. It could be a plot device to explore deeper emotions and create more complex storylines within the NCIS universe.
A plot idea could be that Ziva discovers she's pregnant during a dangerous mission. She has to keep it a secret not only from the bad guys but also from most of the team at first for fear of being taken off the case. Gibbs starts to notice her odd behavior and figures it out. They then have to work together to finish the mission while also protecting their unborn child.
One possible plot could be that Gibbs and Ziva are in a secret relationship. When Ziva discovers she's pregnant, she's initially terrified. Gibbs, on the other hand, is surprisingly calm and determined to support her. They face many challenges, like hiding the pregnancy from their colleagues at first. Gibbs starts to make small changes in their work environment to ensure Ziva's safety and comfort.
Perhaps in the fanfiction, Ziva is kidnapped because she has some crucial information that a rogue agent wants. The NCIS team initially has no leads, but Tony, using his intuition, starts to piece together some small details that lead them in the right direction. They find out that Ziva is being held in a remote location, guarded by heavily armed men. The team has to plan a stealthy rescue operation, and in the end, they succeed in getting Ziva back safely, and she helps them take down the rogue agent.
There are several good ones out there. You could look for fanfics on platforms like Archive of Our Own. Some focus on the relationship between Ziva and Tony during her pregnancy, showing how they support each other and face the new challenges together.
One great fanfiction could be 'Gibbs and Ziva's New Beginning'. In this story, it beautifully depicts their wedding day with all the team members around. The author does an amazing job of showing how their relationship has evolved over time. It's filled with emotional moments, like when Gibbs looks at Ziva walking down the aisle, his eyes full of love and pride.
One possibility could be that it would completely change their dynamic at work. They might become more protective of each other and start to think about their future outside of NCIS. For example, Tony might become more serious and start thinking about settling down in a more permanent way. Ziva, on the other hand, might struggle with how being pregnant would affect her role as an agent.
If Ziva is pregnant in fanfiction, their relationship could become more intimate. They would have to rely on each other more. Tony might become more protective of Ziva.
They could face difficulties with their respective families. Ziva's family might have strong opinions about the pregnancy, and Gibbs' family (if we consider his past family life) could also be a factor. They would need to navigate through these family issues while also dealing with their own feelings about becoming parents.
In this fanfiction scenario, Ziva's pregnancy could also be a way to explore her character further. She has always been tough and independent, but now she has to deal with the physical and emotional changes of pregnancy. It could show a more vulnerable side of her. And Tony would be there to support her, which could lead to some really heartfelt moments between them. Also, the other NCIS team members would have to adjust to this new situation, and that could create some interesting storylines too.
