Well, it could be about all the preparations for their wedding. Maybe they argue over the guest list, like Tony wants to invite all his old buddies from the agency and Ziva has her own list of Mossad contacts. Then there could be a really sweet moment when they choose their wedding rings, with Tony picking out a simple but elegant one for Ziva, and Ziva finding a cool ring that has some meaning related to their adventures together.
One possible plot could be centered around their families. Ziva's family from Israel might have different traditions compared to Tony's. So they have to find a way to incorporate both into the wedding. It could be a story of cultural exchange and compromise, with Ziva's family teaching Tony's family some Israeli wedding customs, and vice versa, all while they're getting ready for the big day.
The plot might involve some sort of drama. For example, an old enemy resurfaces and tries to disrupt the wedding. But Tony and Ziva, being the tough agents they are, work together to stop the threat. And in the end, they have an even more beautiful and meaningful wedding because they overcame this obstacle together.
In this fanfiction, it might start with Tony proposing to Ziva in a very unexpected way. She says yes, and they start planning their wedding. The story could focus on how they blend their different cultures into the wedding. For example, they include some Israeli traditions that Ziva holds dear and some American traditions that Tony loves. Their friends and colleagues also play important roles, like Gibbs giving Tony some fatherly advice before the big day.
Obviously, Tony and Ziva are the most important. But there could also be their friends from work. Like McGee, who might be helping Tony with his vows or something. And Abby could be in charge of the music or the decorations. Then there could be some characters from Ziva's past in Mossad, perhaps an old mentor who comes to give her away at the wedding.
Obviously, Tony and Ziva are the most important characters as it's their wedding. They are the central focus of the story.
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.
Their wedding could be a small and intimate affair. Maybe on a beach, with just their closest friends and family. Ziva would look stunning in a simple white dress, and Tony would be beaming with joy. The ceremony could be a blend of their different cultures, with some Jewish traditions incorporated.
Another plot idea could be that the child starts to suspect that there is more to Tony and Ziva's past work at NCIS than they've been told. So the child begins to investigate on their own, getting into all sorts of trouble. Tony and Ziva then have to deal with not only protecting their child from external threats but also from the child's own curiosity which could put them in danger.
The plot could revolve around how their NCIS colleagues react to the new baby. Some might be excited and offer help, like Gibbs giving some fatherly advice. Others could be a bit jealous or feel left out. In the fanfiction, there could also be a threat to the baby which forces Tony and Ziva to use their NCIS skills to protect their little one.
It could develop slowly. They might start as friends again, carefully testing the waters. Tony could be hesitant because of past hurts, and Ziva might be guarded as well. But as they spend more time together, they gradually become closer.
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.
